20 Antibacterial and Antiviral Herbs and How to Use Them
Antibacterial Herbs
Calendula (Calendula officinalis)
Calendula can be used in first-aid to heal wounds, prevent infection and treat pink eye. Calendula can be prepared a few different ways, including infusions, tinctures, lotions and ointments. No known precautions.
Cinnamon (Cinnamomum zeylanicum)
Cinnamon warms the body, aids in digestion and is used for its antibacterial properties. Cinnamon can be taken as a tea, added to food or the essential oil can be used. When using cinnamon essential oil, remember to use a carrier oil to prevent skin irritation.
Clove (Syzygium aromaticum)
Though clove is typically used as a topical analgesic, clove-infused oil or clove essential oil can also be used to kill bad intestinal bacteria. For internal use, use in cooking or make a cup of clove tea. If using topically, always dilute in a carrier oil.
Garlic (Allium sativum)
As an antibacterial herb, garlic is more effective against several types of bacteria than penicillin. Garlic is also friendlier to the body than antibiotics because it attacks the offending bacteria without wiping out the body's normal flora. Garlic can be used as a tincture, capsule, infused in oil or simply added to your diet. (If cooking with garlic, avoid heating past 130 degrees as that will decrease its potency.)
Echinacea (Echinacea angustifolia)
Taken at the onset of an infection, echinacea can speed the healing process. Echinacea is most effective when taken as a tincture over a long period of time. Do not use echinacea if you have an auto-immune disease.
Oregon Grape Root (Mahonia aquifolium)
Oregon grape root is a potent antibacterial herb, especially when combined with echinacea. Do not take if pregnant, breastfeeding or if you have a history of diabetes, stroke, hypertension or glaucoma. Take as a tincture, but not for long-term treatment as it can decrease Vitamin B absorption.
Marshmallow Root (Althaea officinalis L.)
In addition to pain-easing properties, marshmallow root soothes, lubricates, softens and heals. Marshmallow root also contains tannins found effective against bacteria found in urinary tract infections. Marshmallow root can be taken internally as a tea.
Usnea (Usnea barbata)
This common lichen is antibacterial and antifungal. A powerful antibiotic, usnea is used to treat urinary tract infections, strep and staph infections, respiratory and sinus infections as well as fungal infections like yeast and vaginosis. Usnea is best used as a tincture. No known precautions, but consult an herbalist before using in pregnancy.
Uva Ursi (Arctostaphylos uva-ursi)
Uva Ursi is often used as a tincture or capsule for treating urinary tract infections as it contains compounds effective at killing pathogens typically associated with UTIs. Because of its strength, it should not be used continually for longer than 2 weeks. Not for use by children, pregnant or nursing women or those with kidney disease.
Yarrow (Achillea millefolium)
Tiny yarrow flowers have a number of different uses. As a powder, they stop bleeding quickly. Infused in water, it speeds the healing of canker sores. As a tea, yarrow is used to fight urinary tract infections. Because it can cause uterine contractions, avoid during pregnancy.
Antiviral Herbs
Astragalus Root (Astragalus membranaceus)
Astragalus is one of the antiviral herbs that works by boosting the immune system. Taken internally, either as a capsule, tincture or buy adding it to soup, astragalus root is known to increase your body's defense against viruses. Astragalus root is best used as prevention, so take it during flu season or before going places with large crowds of people. Avoid if you already have a fever.
Cat's Claw (Uncaria tomentosa)
In addition to being an antibacterial, antifungal and antiviral herb, cat's claw is also known for boosting the immune system, increasing your body's protection against illness. Cat's claw can be taken as a tea, tincture or capsule. Do not take during pregnancy.
Cranberry (Vaccinium macrocarpon)
Cranberry is a potent defense against urinary tract infections due to its ability to make the bladder lining too "slippery" to adhere to. Full of antioxidants, cranberry also has antiviral properties and prevents plaque formation on teeth. Cranberry can be taken in a capsule or as juice (make sure it is unsweetened).
Elderberry (Sambucus nigra)
Elderberry is used as a remedy for viral infections like the flu and common cold. Elder stimulates the circulation, causing sweating, effectively cleansing the body. Elderberry syrup is the common delivery method and 1-3 tablespoons can be taken per day during infection. Leaves, roots, seeds, and berries of the raw plant contain cyanide-producing compounds and should not be consumed without cooking properly.
Ginger (Zingiber officinale)
Ginger is another herb known for its antiviral and antibacterial properties. It is used to prevent and decrease duration of the common cold. Ginger can be taken as a tea, in capsule form or added to meals.
Lemon Balm (Melissa officinalis)
An important volatile oil found in lemon balm contains antiviral properties. Lemon balm leaf makes a tasty tea that can also relieve upset stomach and promote calm. May be unsafe to consume during pregnancy.
Licorice Root (Glycyrrhiza glabra)
Licorice is antiviral and antibacterial. It is commonly used for gastric ulcers as it kills H. pylori that causes ulcers without upsetting the stomach. Steep these antiviral herbs as a tea and drink by itself or blended with other herbal teas. Avoid during pregnancy.
Mullein (Verbascum thapsus)
Mullein-infused oil is a great remedy for ear problems, including ear infection, especially when combined with garlic. Use the mullein flowers to create an infused oil.
Olive Leaf (Olea europaea)
As antiviral herbs, olive leaf is used to treat the flu, common cold and herpes. Olive leaf can be taken as a tincture, capsule or tea mixed with mint. Avoid during pregnancy.
Oregano (Origanum vulgare)
In addition to adding great flavor to food, oregano also fights viruses and bacteria as one of the best antiviral herbs available. During an infection, oregano essential oil (high quality only) can be taken in a capsule to speed healing. If using oregano essential oil topically, use a carrier oil to prevent skin irritation.
How to Use Antibacterial and Antiviral Herbs
Tea
Herbal teas are simple to make and require only a cup, hot water and a way to steep your tea. To make an herbal tea, steep 1 tbsp of antibacterial or antiviral herbs in 1 cup hot water for 5-10 minutes. For children, use 1 tsp herbs in the same amount of water.
Infusion
Herbal infusions are simply antibacterial or antiviral herbs prepared in water. They differ from teas in that they use larger quantities of herbs, making a more concentrated preparation. They are steeped in water for several hours in a tightly sealed jar. Using a quart-size canning jar is best because they can hold up well to boiling water.
Once prepared you can drink them iced or heated, add them to baths for soaking wounds or sore muscles or used to make compresses or poultices.
Put a handful of dried herbs in your canning jar. Fill the jar to the fill line with boiling water. Secure the lid tightly and let it steep until the water has completely cooled. Strain out the antibacterial or antiviral herbs and enjoy.
Infused oil
Creating your own infused oil is easy! You can do it with just a few minutes of prep time (the rest is done in the oven).
You'll need:
An oven-proof dish
Fine mesh strainer or cheesecloth
1 cup jojoba or coconut oil
1/2 cup antibacterial or antiviral herbs (one herb or a combination)
Clean, dry jar(s) to store your oil in
Labels
Heat your oven to 200 degrees, then turn it off. To your oven-proof dish, add the oil and herbs, then stir them together. (If the coconut oil is solid, let it melt first in the oven, add the herbs and stir). Put the dish in the oven. After 3 hours take out the herbs and strain the oil into your clean jar(s). Label and store in a cool, dark place.
(Infused oils are different from essential oils. Learn more about essential oils here.)

Clove www.drugs.com/npp/clove.html
Scientific Name(s): Eugenia caryophyllata
Common Name(s): Clove , caryophyllus
www.plantguide.org/_images/clove.jpg
Uses of Clove
Clove has been used for its antiseptic and analgesic effects and has been studied for use as an anticoagulant and anti-inflammatory effects. However, research reveals little or no clinical data on the use of clove for any indication.
Botany
The clove plant grows in warm climates and is cultivated commercially in Tanzania, Sumatra, the Maluku (Molucca) Islands, and South America. The tall evergreen plant grows up to 20 m and has leathery leaves. The clove spice is the dried flower bud. Essential oils are obtained from the buds, stems, and leaves. The buds or cloves are strongly aromatic
History
Clove has a long history of culinary and medicinal use. The oil was used as an expectorant and antiemetic with inconsistent clinical results. Clove tea was used to relieve nausea. Use of the oil in dentistry as an analgesic and local antiseptic continues today. It also has been used topically as a counterirritant.
Chemistry
Clove buds yield approximately 15% to 20% of a volatile oil that is responsible for the characteristic smell and flavor. The bud also contains a tannin complex, a gum and resin, and a number of glucosides of sterols. The principal constituent of distilled clove bud oil (60% to 90%) is eugenol (4-allyl-2-methoxyphenol). The oil also contains about 10% acetyleugenol and small quantities of gallic acid, sesquiterpenes, furfural, vanillin, and methyl-n-amyl ketone. Other constituents include flavonoids, carbohydrates, lipids, oleanolic acid, rhamnetin, and vitamins.
Clove oil is applied for the symptomatic treatment of toothaches and is used for the treatment of dry socket (postextraction alveolitis).
Clove oil is reported to have antihistaminic and antispasmotic properties, most likely due to the presence of eugenyl acetate. Cloves are also said to have a positive effect on healing stomach ulcers. A 15% tincture of cloves is effective in treating topical fungal, ringworm infections. As with many other volatile oils, clove oil inhibits gram-positive and gram-negative bacteria. Clove oil also has anthelminthic properties.
Cinnamon www.drugs.com/npp/cinnamon.html
Scientific Name(s): Cinnamomum verum, C. cassia, C. zeylanicum, C. loureirii.
Common Name(s): Cinnamon, cinnamomon, ceylon cinnamon, Chinese cinnamon, Chinese cassia, Saigon cinnamon
unitproj1.library.ucla.edu/biomed/spice/images/historical_CINNAMON.jpg
Uses of Cinnamon
Cinnamon is used as a spice and an aromatic. The bark or oil has been used to combat microorganisms, diarrhea and other GI disorders, and dysmenorrhea. Research interest has focused on cinnamon's potential as an insulin-like analog, an anti-inflammatory agent, an antioxidant, and an antimicrobial substance.
Botany
Cinnamon spice is derived from the brown bark of the tree by grinding the bark into a fine powder. The plant is native to Sri Lanka, southeastern India, Indonesia, South America, and the West Indies.
Chemistry
The essential oil is primarily composed of 65% to 80% cinnamaldehyde and lesser amounts of other phenols and terpenes, including eugenol, trans-cinnamic acid, hydroxycinnamaldehyde, o-methoxycinnamaldehyde, cinnamyl alcohol and its acetate, limonene, α-terpineol, tannins, mucilage, oligomeric procyanidins, and trace amounts of coumarin. Differing material origins and extraction techniques are reported to alter the chemical composition of the extracts, and hence may impact the intended medicinal (and experimental) effects.
Antimicrobial activity
Conflicting evidence exists for the action of cinnamon on Helicobacter pylori . Cinnamon extracts have been shown to exert in vitro activity against some common human pathogens and fungicidal activity against plant pathogens. In vitro inhibition of bacterial endotoxin has been demonstrated by an unidentified component in cinnamon bark. The essential oils of cinnamon were shown to halt mycelial growth and aflatoxin synthesis in Aspergillus parasiticus at a concentration of only 0.1%.
Nutmeg www.drugs.com/npp/nutmeg.html
Scientific Name(s): Myristica fragrans
Common Name(s): Nutmeg, mace, magic, muscdier, nux moschata, myristica oil, muskatbaum
www.herbdatanz.com/Nutmeg.gif
Uses of Nutmeg
Nutmeg and mace, widely accepted as flavoring agents, are used in higher doses for their aphrodisiac and psychoactive properties.
Botany
Mace and nutmeg are 2 slightly different flavored spices, both originating from the fruit of the nutmeg tree, Myristica fragrans . This slow-growing evergreen grows to more than 20 m and is cultivated in India, Ceylon, Malaysia, and Granada. The fruit, which is called a drupe or a nutmeg apple, is similar in appearance to a peach or an apricot. When the mature fruit splits open, the nutmeg (stony endocarp or seed surrounded by a red, slightly fleshy network or aril) is exposed. The dried aril alone is called mace. The nut is removed and dried to produce nutmeg.
History
Nutmeg is a widely used food spice that has received attention as an alternative hallucinogen. Nutmeg and mace have been used in Indian cooking and folk medicine. The folk uses of nutmeg have included the treatment of gastric disorders and rheumatism, and it has been used as a hypnotic and an aphrodisiac. During the 6th century AD, nutmeg and mace were imported by Arab traders. By the 12th century, these spices were well known in Europe. At the turn of the 19th century, interest developed in the use of nutmeg as an abortifacient and a stimulant for menses. These properties have been largely discounted but remain a persistent cause of nutmeg intoxication in women.
Chemistry
Nutmeg seeds contain 20% to 40% of a fixed oil, commonly called nutmeg butter. This oil contains myristic acid, trymiristin, and glycerides of lauric, tridecanoic, stearic, and palmitic acids.
Nutmeg also yields 8% to 15% of an essential oil that is believed to be partially responsible for the effects associated with nutmeg intoxication. The essential oil contains myristicin, elemicin, eugenol, and safrole. The essential oils of nutmeg and mace are very similar in chemical composition and aroma, with wide color differences (brilliant orange to pale yellow). Mace oil appears to have a higher myristicin content than nutmeg oil.
Also present in the oil are sabinene, cymene alpha-thujene, gamma-terpinene, and monoterpene alcohols in smaller amounts. Phenolic compounds found in nutmeg are reported to have antioxidant properties. Other isolated compounds include the resorcinols malabaricone B and malabaricone C, as well as lignans and neolignans.
Antimicrobial effects
The oils of mace and nutmeg and their individual components have been assessed for their antimicrobial activity in vitro. Activity has been shown against some oral microorganisms, including S. mutans, Porphyromonas gingivalis , and others. Activity against other bacteria includes some strains of Escherichia coli, some strains of Salmonella typhi, Bacillus subtilis, Staphylococcus aureus, and Listeria monocytogenes. Anti-viral effect has also been reported against human rotavirus.
Reports of activity against fungi is conflicting, with no activity against Aspergillus but activity against some dermatophytes has been found.
===============================================
The spices cloves, nutmeg, cinnamon, bay leaves contain eugenol, a clear to pale yellow oily liquid with a pleasant, spicy, clove-like odor, that can be extracted from the essential oils from these plants.
Eugenol
Eugenol is used in perfumeries, flavorings, essential oils and in medicine as a local antiseptic and anaesthetic. Combining zinc oxide and eugenol forms zinc oxide eugenol which can be used as a filling or cement material used in dentistry. It is classified as an intermediate restorative material and has anaesthetic and antibacterial properties. It is sometimes used in the management of dental caries as a "temporary filling".

Oregano www.drugs.com/npp/oregano.html
Scientific Name(s): Origanum vulgare
Common Name(s): Mediterranean oregano, mountain mint, wild marjoram, winter marjoram, wintersweet
www.yankeegardener.com/seeds/herb-oregano-lg.jpg
Uses of Oregano
Aside from its culinary application, oregano exhibits antimicrobial and antioxidant actions and has possible activity as an antispasmodic and in diabetes. However, there is no clinical evidence to support the use of oregano in any indication.
Botany
Common or wild oregano is a perennial plant native to the Mediterranean region and Asia and cultivated in the United States. Its creeping rootstock produces a square, downy, purplish stem with opposite ovate leaves. Stems can grow up to 76 cm tall and are dotted with small depressions. Purple, 2-lipped flowers grow in terminal clusters from July to October.
History
Oregano has been a common ingredient in Spanish, Mexican, and Italian dishes as a spice and flavoring agent for hundreds of years. Its initial purpose was as a warming digestive and circulatory stimulant. It has been used in perfumery for its volatile oil contents, especially in scenting soaps.
The antiseptic qualities of aromatic and medicinal plants and their extracts have been recognized since antiquity. It has been suggested that an infusion of the fresh herb is beneficial in treating an upset stomach and indigestion, headache, colic, and nervous complaints, as well as for coughs and other respiratory ailments. An infusion of the flowers has been used to prevent seasickness. The oil has been used externally in liniments and lotions and to ease toothache. It has also been used as an ant repellent.
Chemistry
Oregano contains oleanolic and ursolic acids, flavonoids and hydroquinones, caffeic, rosemarinic, and lithospermic acid, tannins, and phenolic glycosides. Phenolic compounds represent 71% of the total oil. The polar phenols thymol and carvacrol are responsible for many of the properties of the essential oil, as well as p-cymene and terpinene.
Antimicrobial activity
Studies have compared the effects of oregano essential oil, thymol, and carvacrol on fungi. All 3 completely inhibited fungal growth of Aspergillus and Penicillium species. Oregano oil also appears to have some activity against Candida species, possibly because of its carvacrol content.
The volatile oils of oregano have demonstrated in vitro antibacterial activity against a wide range of gram-positive and gram-negative microorganisms including Listeria, Pseudomonas, Proteus, Salmonella, and Clostridium species, as well as some methicillin-resistant Staphylococci. Low to moderate activity against Helicobacter pylori has been reported. Oregano oil appears to inhibit organisms at relatively low concentrations, and its activity could be due to the phenolic components thymol and carvacrol.
There are also various reports describing antiparasitic activity of oregano.
The oil of Origanum vulgare has been shown to eradicate common parasites in chickens and pheasants. In vitro experiments have shown activity against Trypanosoma cruzi.
========================================
The spices oregano and thyme contain Thymol (and a closely related substance called carvacrol), which have been shown to possess bacteriocidal, fungicidal, molluscicidal and insecticidal properties.
C10H14O Thymol
The main therapeutic application for thymol is in dental preparations to kill odor-producing bacteria. It is also employed as a preservative on the strength of its antimicrobial and antioxidant properties. In the mollusc Lymnaea acuminata, lethal doses of thymol affected the activity of key nervous tissue enzymes, and this was postulated to be the cause of toxicity As yet, no mechanism of action has been identified for thymol lethality, or that of related monoterpenoids, towards insects.
Recently, thymol was shown to have a direct agonist effect on heterologously expressed human GABAA receptors resembling that of the anaesthetic propofol.
The active ingredients of Listerine include essential oils (thymol, eucalyptol, menthol, methyl salicylate) with anti-fungal activity. This early ad for Listerine recommends its use for treating dandruff.

Onion www.drugs.com/npp/onion.html
Scientific Name(s): Allium cepa
Common Name(s): Onion
aggie-horticulture.tamu.edu/extension/vegetable/cropguides/pictures/onion.jpg
Uses of Onion
Onion is used as an antimicrobial, cardiovascular-supportive, hypoglycemic, antioxidant/anticancer, and asthma-protective agent. However, few clinical trials are available to support the use of onion for any indication. In folk medicine, onion has been used for asthma, bronchitis, whooping cough, and similar ailments. Other uses include the treatment of stingray wounds, warts, acne, appetite loss, urinary tract disorders, and indigestion. Onion skin dye has been used as an egg and cloth coloring.
Botany
The onion plant is a perennial herb growing to about 1.2 m, with 4 to 6 hollow, cylindrical leaves. On top of the long stalk, greenish-white flowers are present in the form of solitary umbels growing up to 2.5 cm wide. The seeds of the plant are black and angular. The underground bulb, which is used medicinally, is comprised of fleshy leaf sheaths forming a thin-skinned capsule. The onion is one of the leading vegetable crops in the world.
History
The onion is believed to have been domesticated in central Asia. Onions were used as early as 5,000 years ago in Egypt, as depicted on ancient monuments; ancient Greek and Roman records also refer to the onion. During the Middle Ages, onions were consumed throughout Europe. They later were thought to guard against evil spirits and the plague, probably because of their strong odor. Onion skin dye has been used for egg and cloth coloring for many years in the Middle East and Europe. Columbus was said to have brought the onion to America. Folk healers used the onion to prevent infection. The combination of onions and garlic cooked in milk is a European folk remedy used to clear congestion. Onions also are used in homeopathic medicine.
Chemistry
Onions contain 89% water, 1.5% protein, and vitamins, including B1 , B2 , and C, along with potassium. Polysaccharides such as fructosans, saccharose, and others are also present, as are peptides, flavonoids, and essential oil. Onion contains alliin and similar sulfur compounds, including allylalliin and methyl and propyl compounds of cysteine sulfoxide. Sulfur and other compounds of A. cepa have been analyzed. Prostaglandins also have been identified in onion.
Antimicrobial effects
Onion has reported antibacterial, antiparasitic, and antifungal actions. Growth of oral pathogenic bacteria, including Streptococcus mutans, Porphyromonas gingivalis, and Prevotella intermedia, organisms associated with dental caries and periodontitis, was prevented by onion extracts. Onion juice or oil also have inhibited growth of other gram-positive bacteria and gram-negative bacteria such as Klebsiella pneumoniae. Antifungal actions of onion include inhibition of yeasts and a number of molds.
The antibacterial, antiparasitic, and antifungal actions of onion is believed to be due to a number of sulfur containing compounds such as alliin, allylalliin, diallyl disulfide and the methyl and propyl compounds of cysteine sulfoxide.
Onions are also noted for their ability to make you cry. This effect is due to one of these propyl sulfoxides which is converted to propanethial-S-oxide which then escapes from the onion in vapor form and hydrolyzes to sulfuric acid when it reacts with moisture, causing the familiar eye irritation and lacrimation.
www.chm.bris.ac.uk/motm/pso/psoc.htm
The health promoting reputation of onions is legendary and may be due to other compounds found in the bulb. For instance, prostaglandins, which have profound physiological effects in animals, also have been reported to exist in onion. (Al-Nagdy S, Abdel Rahman MO, Heiba HI. Comp Biochem Physiol C . 1986;85:163-166).
Garlic www.drugs.com/npp/garlic.html
Scientific Name(s): Allium sativum
Common Name(s): Garlic, allium, stinking rose, rustic treacle, nectar of the gods, camphor of the poor, poor man's treacle
www.designmom.com/uploaded_images/cj4.garlic1-742608.jpg
Uses of Garlic
Evidence suggests that garlic may beneficially affect cholesterol and lipids. Among its traditional uses, it has been employed for its antiseptic and antibacterial properties. Other potential areas of use include GI disorders and oncology.
Botany
A perennial bulb with a tall, erect flowering stem that grows to 2 to 3 feet. The plant produces pink to purple flowers that bloom from July to September. The bulb is odiferous.
History
The name Allium comes from the Celtic word all meaning burning or smarting. Garlic was valued as an exchange medium in ancient Egypt; its virtues were described in inscriptions on the Great Pyramid of Cheops. The folk uses of garlic have ranged from the treatment of leprosy in humans to managing clotting disorders in horses. Physicians prescribed the herb during the Middle Ages to cure deafness and the American Indians used garlic as a remedy for earaches, flatulence, and scurvy.
Chemistry
Fresh garlic is a source of numerous vitamins, minerals, and trace elements, although most are only found in minute quantities. Garlic contains the highest sulfur content of any member of the genus Allium. Two trace elements, germanium and selenium, are found in detectable quantities and have been postulated to play a role in the herb's antitumor effect.
Garlic contains about 0.5% of a volatile oil composed of sulfur-containing compounds (diallyldisulfide, diallyltrisulfide, methylallyltrisulfide). The bulbs contain an odorless, colorless, sulfur-containing amino acid called alliin (S-allyl-L-cysteine sulfoxide), which has no known pharmacologic activity. When the bulb is ground, the enzyme allinase is released, resulting in the conversion of alliin to 2-propenesulfenic acid, which dimerizes to form allicin. Allicin gives the pungent characteristic odor to crushed garlic and is believed to be responsible for some of the pharmacologic activity of the plant.
Uses of Garlic
Evidence suggests that garlic may beneficially affect cholesterol and lipids. Among its traditional uses, it has been employed for its antiseptic and antibacterial properties. Other potential areas of use include GI disorders and oncology.
Antiseptic/Antibacterial properties
The antiseptic and antibacterial properties of garlic have been known for centuries. As recently as World War II, garlic extracts were used to disinfect wounds. During the 1800s, physicians routinely prescribed garlic inhalation for the treatment of tuberculosis.
Garlic extracts inhibit the growth of numerous strains of Mycobacterium, but at concentrations that may be difficult to achieve in human tissues. Preparations containing garlic extracts are used widely in Russia and Japan. Both gram-positive and gram-negative organisms are inhibited in vitro by garlic extracts. The potency of garlic is such that 1 mg is equivalent to 15 Oxford units of penicillin, making garlic about 1% as active as penicillin.
Garlic extracts have shown antifungal activity when tested in vitro and their use has been suggested in the treatment of oral and vaginal candidiasis. In an attempt to quantitate the in vivo activity of garlic extracts, one research group administered 25 mL of fresh garlic extract orally to volunteers. Serum and urine samples were tested for antifungal activity against 15 species of fungal pathogens. While serum exhibited anticandidal and anticryptococcal activity within 30 minutes after ingestion, no biological activity was found in urine. The findings suggest that while garlic extracts may exhibit some antifungal activity in vivo, they are probably of limited use in the treatment of systemic infections.
Anise www.drugs.com/npp/anise.html
Scientific Name(s): Pimpinella anisum
Common Name(s): Anise, aniseed, sweet cumin
unitproj1.library.ucla.edu/biomed/spice/images/historical_ANISE.jpg
Uses of Anise
Anise is used as a flavoring in alcohols, liqueurs, dairy products, gelatins, puddings, meats, and candies, and as a scent in perfumes, soaps, and sachets. The oil has also been used to treat lice, scabies, and psoriasis. Anise frequently is used as a carminative and expectorant. Anise also is used to decrease bloating and settle the digestive tract in children. In high doses, it is used as an antispasmodic and an antiseptic and for the treatment of cough, asthma, and bronchitis. However, research reveals no clinical data regarding the use of anise for any of these applications.
History
Anise has a history of use as a spice and a fragrance. It has been cultivated in Egypt for at least 4,000 years. Records of its use as a diuretic and treatment of digestive problems and toothache are seen in medical texts from this era. In ancient Greek history, writings explain how anise helps breathing, relieves pain, stimulates urination, and eases thirst. The essential oil has been used commercially since the 1800s. The fragrance is used in food, soap, creams, and perfumes. Anise often is added to licorice candy or used as a �licorice� flavor substitute; it is also a fragrant component of anisette liqueur.
Chemistry
Anise oil (1% to 4%) is obtained by steam distillation of the dried fruits of the herb. The highest quality oils result from anise seeds of ripe umbels in the center of the plant. A major component of the oil is trans-anethole (75% to 90%), responsible for the characteristic taste and smell, as well as for its medicinal properties.
The volatile oil also has related compounds that include estragole (methyl chavicol, 1% to 2%), anise ketone (p-methoxyphenylacetone), and beta caryophyllene. In smaller amounts are anisaldehyde, anisic acid, limonene, alpha-pinene, acetaldehyde, p-cresol, cresol, and myristicin (the psychomimetic compound previously isolated from nutmeg).
Constituents of the whole seed include coumarins, such as umbelliferone, umbelliprenine, bergapten, and scopoletin. Lipids (16%) include fatty acids, beta-amyrin, stigmasterol, and its salts. Flavonoids in aniseed include rutin, isoorientin, and isovitexin. Protein (18%) and carbohydrate (50%) are also present. Terpene hydrocarbons in the plant also have been described.
Antimicrobial
Anise has been evaluated for its antimicrobial action against gram-negative and gram-positive bacteria and also a few fungi. Anise is used in dentifrices as an antiseptic and in lozenges and cough preparations for its weak antibacterial effects.
Sassafras www.drugs.com/npp/sassafras.html
Scientific Name(s): Sassafras albidum
Common Name(s): Sassafras, saxifras, ague tree, cinnamon wood, saloop
pictopia.com/perl/get_image?provider_id=262&size=550x550_mb&ptp_photo_id=1796302
Uses of Sassafras
Sassafras has been used historically for a variety of illnesses, and is now banned in the US, even for use as a flavoring or fragrance.
Botany
Sassafras is the name applied to three species of trees, two native to eastern Asia and one native to eastern North America. Fossils show that sassafras was once widespread in Europe, North America and Greenland. The trees grow up to 100 feet in height and 6 feet in diameter, though they are usually smaller. Sassafras bears leaves 10 to 15 cm long that are oval on older branches but mitten-shaped or three-lobed on younger shoots and twigs. All parts of the tree are strongly aromatic. The drug is from the peeled root of the plant (root bark).
History
Native Americans have used sassafras for centuries and told early settlers that it would cure a variety of ills. The settlers then exported it to Europe, where it was found to be ineffective.
Over the years the oil obtained from the roots and wood has been used as a scent in perfumes and soaps. The leaves and pith, when dried and powdered, have been used as a thickener in soups. The roots are often dried and steeped for tea, and sassafras was formerly used as a flavoring in root beer. Its use as a drug or food product has been banned by the US Food and Drug Administration (FDA) as carcinogenic; however, its use and sale persist throughout the United States. Medicinally, sassafras has been applied to insect bites and stings to relieve symptoms.
Chemistry
The main constituent of sassafras oil is safrole, which chemically is p-allyl-methylenedioxybenzene, which comprises up to 80% of the oil. Volatile oil also contains anethole, pinene apiole, camphor, eugenol and myristicin.
The plant contains less than 0.2% total alkaloids (primarily boldine and its derivatives and reticuline) along with tannins, resins, mucilage and wax. Six alkaloids, aporphine and benzylsoquinoline derivatives, have been found in root bark. Two antimicrobial neolignans, magnolol and its related isomer (isomagnolol), from related species S. randaiensis have been isolated.
Sassafras Uses and Pharmacology
Sassafras has been used as a sudorific agent, a flavoring agent for dentifrices, root beers and tobaccos, and for treatment of eye inflammation. Extracts of the roots and bark have been found to mimic insect juvenile hormone in Oncopeltus fasciatus. The oil has been applied externally for relief of insect bites and stings and for lice. Other external uses include treatment of rheumatism, gout, sprains, swelling and cutaneous eruptions. A recent report compares safrole (the main constituent from sassafras oil), to indomethacin for anti-inflammatory activity and pain treatment in mice.
The plant has been reported to have antineoplastic activity and to induce cytochrome P-488 and P-450 enzymes. Sassafras is said to be antagonistic to certain alcohol effects. Alcohol extracts of the related S. randaiense exhibit antimicrobial and antifungal activity in vitro, and this activity appears to be due to the presence of magnolol and isomagnolol.
Noni www.drugs.com/npp/noni.html
Scientific Name(s): Morinda citrifolia
Common Name(s): Morinda, noni, hog apple, Indian mulberry, mengkoedoe, mora de la India, pain killer, ruibarbo caribe, wild pine
www.nannisnoni.com/High%20Res%20Noni.jpg
Uses of Noni
Morinda has been used for heart remedies, arthritis, headache, digestive and liver ailments.
Botany
The morinda plant, native to Asia, Australia and Polynesia, is a 3 to 8 m high tree or shrub. Its evergreen leaves are oblong and 10 to 45 cm in length. The plant's white flowers are tubular, with conelike heads. The fruit is yellow-white in color, oval in shape, about the size of a potato and has a �bumpy� surface. The ripened fruit has a characteristic cheese-like, offensive odor. Each fruit contains 4 seeds, 3 mm in length.
History
It is believed that Polynesian healers have used morinda fruits for thousands of years to help treat a variety of health problems such as diabetes, high blood pressure, arthritis and aging. Ancient healing manuscripts cite the fruit as a primary ingredient in natural healing formulations. Today, fruit preparations are sold as juice, in dried �fruit-leather� form and as a dry extract in capsules.
Chemistry
Morinda citrifolia fruits contain essential oils with hexoic and octoic acids, paraffin and esters of ethyl and methyl alcohols. Ripe fruit contains n-caproic acid, presumably responsible for its distinctive odor, known to attract insects such as Drosophilia sechellia. Fresh plants contain anthraquinones, morindone and alizarin. A new anthraquinone glycoside from morinda heartwood has recently been described. Hawaiian researcher Ralph Heinicke discovered a small plant alkaloid he termed �xeronine.� Damnacanthal, morindone and alizarin are present in cell suspension cultures.
Noni Uses
Morinda citrifolia has been used medicinally for heart remedies, arthritis (by wrapping the leaves around affected joints), headache (local application of leaves on forehead), GI and liver ailments.
Alcoholic extracts of M. citrifolia leaves displayed good anthelmintic activity in vitro against the human parasite Ascaris lumbricoides . Lyophilized aqueous root extracts of the plant showed central analgesic activity, among other effects, suggesting sedative properties of the plant as well.
Wintergreen www.drugs.com/npp/wintergreen.html
Scientific Name(s): Gaultheria procumbens
Common Name(s): Wintergreen, teaberry, checkerberry, gaultheria oil, boxberry, deerberry, mountain tea, Canada tea, partridgeberry
members.tripod.com/~Elspeth_Stormdancer/Herbs/Herblist/herbpix/wintergreen.gif
Uses of Wintergreen
In addition to being used as a flavoring, wintergreen and its oil have been used in topical analgesic and rubefacient preparations for the treatment of muscular and rheumatic pain. However, research reveals no clinical data regarding the use of wintergreen for any condition.
Botany
Wintergreen is a perennial evergreen shrub with thin, creeping stems from which leathery leaves with toothed, bristly margins arise. It is a low-growing plant native to eastern North America and usually is found in woodland and exposed mountainous areas. Its small, waxy, white or pale pink flowers bloom in late summer, developing a scarlet fruit. The aromatic leaves and fruits are edible.
History
American Indians reportedly used wintergreen for treating back pain, rheumatism, fever, headaches, and sore throats. The plant and its oil have been used in traditional medicine as an anodyne, analgesic, carminative, astringent, and topical rubefacient.
Wintergreen oil is obtained by steam distillation of the warmed, water-macerated leaves. It is used interchangeably with sweet birch oil or methyl salicylate for flavoring foods and candies. The highest amount of methyl salicylate typically used in candy flavoring is 0.04%.
Wintergreen berries have been used to make pies. A tea made from the leaves was used as a substitute for black tea, Camellia sinensis, during the Revolutionary War. Wintergreen tea has been used to relieve cold symptoms and muscle aches.
Chemistry
Wintergreen oil contains approximately 98% to 100.5% of the methyl ester, methyl salicylate. The plant has little odor or flavor until the methyl salicylate is freed. During steam distillation, the gaultherin (also described as primeveroside or monotropitoside) present in the leaves is enzymatically hydrolyzed to methyl salicylate. The purified methyl salicylate is subsequently obtained through distillation. In addition, the sugars D-glucose and D-xylose are obtained. The yield of oil from the leaves is in the range of 0.5% to 0.8%.

Ginger www.drugs.com/npp/ginger.html
Scientific Name(s): Zingiber officinale Roscoe; occasionally Z. capitatum
Common Name(s): Ginger, ginger root, black ginger, zingiberis rhizoma
www.botanical.com/botanical/mgmh/g/ginger13-l.jpg
Uses of Ginger
Ginger and its constituents have antiemetic, cardiotonic, antithrombotic, antibacterial, antioxidant, antitussive, antihepatotoxic, anti-inflammatory, antimutagenic, stimulant, diaphoretic, diuretic, spasmolytic, immunostimulant, carminative, and cholagogue actions. Ginger is used to promote gastric secretions, increase intestinal peristalsis, lower cholesterol levels, raise blood glucose, and stimulate peripheral circulation. Traditionally used to stimulate digestion, its modern uses include prophylaxis for nausea and vomiting (associated with motion sickness, hypermesis gravidarum, and anesthesia), dyspepsia, lack of appetite, anorexia, colic, bronchitis, and rheumatic complaints. Ginger can be used as a flavoring or spice as well as a fungicide and pesticide.
Botany
A native of tropical Asia, this perennial is cultivated in tropical climates such as Australia, Brazil, China, India, Jamaica, West Africa, and parts of the US. The rhizome is used medicinally and as a culinary spice. The rhizome is harvested between 6 and 20 months; taste and pungency increase with maturity. The plant carries a green-purple flower in terminal spikes; the flowers are similar to orchids.
History
Medicinal use of ginger dates back to ancient China and India; references to its use are found in Chinese pharmacopoeias, the Sesruta scriptures of Ayurvedic medicine as well as Sanskrit writings. Once its culinary properties were discovered in the 13th century, use of this herb became widespread throughout Europe. In the Middle Ages, it held a firm place in apothecaries for travel sickness, nausea, hangovers, and flatulence.
Ginger and its constituents are stated to have antiemetic, cardiotonic, antithrombotic, antibacterial, antioxidant, antitussive, antihepatotoxic, anti-inflammatory, antimutagenic, stimulant, diaphoretic, diuretic, spasmolytic, immunostimulant, carminative, and cholagogue actions as well as to promote gastric secretions, increase intestinal peristalsis, lower cholesterol levels, raise blood glucose, and stimulate peripheral circulation. Traditionally, ginger is used as an acrid bitter to strengthen and stimulate digestion. Modern uses include prophylaxis for nausea and vomiting (associated with motion sickness, hyperemesis gravidarum and surgical anesthesia), dyspepsia, lack of appetite, anorexia, colic, bronchitis, and rheumatic complaints. The food industry uses ginger oil as a spice and ginger extract in the manufacturing of ginger ale. In China, ginger root and stem are used as pesticides against aphids and fungal spores.
Ginger is in the official pharmacopoeias of Austria, China, Egypt, Great Britain, India, Japan, the Netherlands, and Switzerland. It is approved as a nonprescription drug in Germany and as a dietary supplement in the US.
Chemistry
It had long been believed that the �pungent principles� of ginger were also responsible for its pharmacologic activity, and this has been found to be accurate. The characteristic aroma of ginger is due mainly to the presence of zingiberol in the volatile oil.
The major constituents in ginger rhizomes are carbohydrates (50 to 70%), which are present as starch. The concentration of lipids is 3 to 8% and includes free fatty acids (eg, palmitic, oleic, linoleic, linolenic, capric, lauric, myristic), triglycerides, and lecithins. Oleoresin provides 4 to 7.5% of pungent substances as gingerol homologues, shogaol homologues, zingerone, and volatile oils. Volatile oils are present in 1 to 3% concentrations and consist mainly of the sesquiterpenes beta-besabolene and zingiberene; other sesquiterpenes include zingiberol and zingiberenol; numerous monoterpenes are also found. Amino acids, raw fiber, ash, protein, phytosterols, vitamins (ie, nicotinic acid and vitamin A), and minerals are among the other constituents.
Analyses of the oleoresins have resulted in the identification of a class of structurally related cardiotonic compounds called gingerols, which upon dehydration, form shogaols and degrade further to zingerone. [6]-gingerol and [6]-shogaol are the main components however, the pharmacologically active compounds [6]- and [10]-dehydrogingerdione, and [6]- and [10]-gingerdione have also been identified.
Ginger Uses
Human clinical trials have examined ginger's antiemetic effects related to kinetosis (motion sickness), perioperative anesthesia, and hyperemesis gravidarum. However, little is still known regarding its human pharmacology in these settings. Animal studies have described enhanced GI transport as well as anti-5-hydroxytryptamine (5HT 3 ) and possible CNS antiemetic effects.
Ginger has been reported to have weak fungicidal, strong antibacterial, and anthelmintic properties. Active constituents have been shown to inhibit reproduction of Escherichia coli, Proteus species, Staphylococci, Streptococci, and Salmonella but to stimulate the growth of Lactobacilli. In vitro anthelmintic activity has been documented for the volatile oil of Z. purpureum and activity has also been reported against parasites, such as Schistosoma and Anisakis.
The cytotoxic compound zerumbone and its epoxide have been isolated from the rhizomes of Z. zerumbet . This plant, also a member of the family Zingiberaceae, has been used traditionally in China as an antineoplastic.
Antibacterial Activity of Selected Australian Native Plant Extracts: plant herbs au_1.pdf (71.95 KB)
Antibacterial Herbs
Calendula (Calendula officinalis)
Calendula can be used in first-aid to heal wounds, prevent infection and treat pink eye. Calendula can be prepared a few different ways, including infusions, tinctures, lotions and ointments. No known precautions.
Cinnamon (Cinnamomum zeylanicum)
Cinnamon warms the body, aids in digestion and is used for its antibacterial properties. Cinnamon can be taken as a tea, added to food or the essential oil can be used. When using cinnamon essential oil, remember to use a carrier oil to prevent skin irritation.
Clove (Syzygium aromaticum)
Though clove is typically used as a topical analgesic, clove-infused oil or clove essential oil can also be used to kill bad intestinal bacteria. For internal use, use in cooking or make a cup of clove tea. If using topically, always dilute in a carrier oil.
Garlic (Allium sativum)
As an antibacterial herb, garlic is more effective against several types of bacteria than penicillin. Garlic is also friendlier to the body than antibiotics because it attacks the offending bacteria without wiping out the body's normal flora. Garlic can be used as a tincture, capsule, infused in oil or simply added to your diet. (If cooking with garlic, avoid heating past 130 degrees as that will decrease its potency.)
Echinacea (Echinacea angustifolia)
Taken at the onset of an infection, echinacea can speed the healing process. Echinacea is most effective when taken as a tincture over a long period of time. Do not use echinacea if you have an auto-immune disease.
Oregon Grape Root (Mahonia aquifolium)
Oregon grape root is a potent antibacterial herb, especially when combined with echinacea. Do not take if pregnant, breastfeeding or if you have a history of diabetes, stroke, hypertension or glaucoma. Take as a tincture, but not for long-term treatment as it can decrease Vitamin B absorption.
Marshmallow Root (Althaea officinalis L.)
In addition to pain-easing properties, marshmallow root soothes, lubricates, softens and heals. Marshmallow root also contains tannins found effective against bacteria found in urinary tract infections. Marshmallow root can be taken internally as a tea.
Usnea (Usnea barbata)
This common lichen is antibacterial and antifungal. A powerful antibiotic, usnea is used to treat urinary tract infections, strep and staph infections, respiratory and sinus infections as well as fungal infections like yeast and vaginosis. Usnea is best used as a tincture. No known precautions, but consult an herbalist before using in pregnancy.
Uva Ursi (Arctostaphylos uva-ursi)
Uva Ursi is often used as a tincture or capsule for treating urinary tract infections as it contains compounds effective at killing pathogens typically associated with UTIs. Because of its strength, it should not be used continually for longer than 2 weeks. Not for use by children, pregnant or nursing women or those with kidney disease.
Yarrow (Achillea millefolium)
Tiny yarrow flowers have a number of different uses. As a powder, they stop bleeding quickly. Infused in water, it speeds the healing of canker sores. As a tea, yarrow is used to fight urinary tract infections. Because it can cause uterine contractions, avoid during pregnancy.
Antiviral Herbs
Astragalus Root (Astragalus membranaceus)
Astragalus is one of the antiviral herbs that works by boosting the immune system. Taken internally, either as a capsule, tincture or buy adding it to soup, astragalus root is known to increase your body's defense against viruses. Astragalus root is best used as prevention, so take it during flu season or before going places with large crowds of people. Avoid if you already have a fever.
Cat's Claw (Uncaria tomentosa)
In addition to being an antibacterial, antifungal and antiviral herb, cat's claw is also known for boosting the immune system, increasing your body's protection against illness. Cat's claw can be taken as a tea, tincture or capsule. Do not take during pregnancy.
Cranberry (Vaccinium macrocarpon)
Cranberry is a potent defense against urinary tract infections due to its ability to make the bladder lining too "slippery" to adhere to. Full of antioxidants, cranberry also has antiviral properties and prevents plaque formation on teeth. Cranberry can be taken in a capsule or as juice (make sure it is unsweetened).
Elderberry (Sambucus nigra)
Elderberry is used as a remedy for viral infections like the flu and common cold. Elder stimulates the circulation, causing sweating, effectively cleansing the body. Elderberry syrup is the common delivery method and 1-3 tablespoons can be taken per day during infection. Leaves, roots, seeds, and berries of the raw plant contain cyanide-producing compounds and should not be consumed without cooking properly.
Ginger (Zingiber officinale)
Ginger is another herb known for its antiviral and antibacterial properties. It is used to prevent and decrease duration of the common cold. Ginger can be taken as a tea, in capsule form or added to meals.
Lemon Balm (Melissa officinalis)
An important volatile oil found in lemon balm contains antiviral properties. Lemon balm leaf makes a tasty tea that can also relieve upset stomach and promote calm. May be unsafe to consume during pregnancy.
Licorice Root (Glycyrrhiza glabra)
Licorice is antiviral and antibacterial. It is commonly used for gastric ulcers as it kills H. pylori that causes ulcers without upsetting the stomach. Steep these antiviral herbs as a tea and drink by itself or blended with other herbal teas. Avoid during pregnancy.
Mullein (Verbascum thapsus)
Mullein-infused oil is a great remedy for ear problems, including ear infection, especially when combined with garlic. Use the mullein flowers to create an infused oil.
Olive Leaf (Olea europaea)
As antiviral herbs, olive leaf is used to treat the flu, common cold and herpes. Olive leaf can be taken as a tincture, capsule or tea mixed with mint. Avoid during pregnancy.
Oregano (Origanum vulgare)
In addition to adding great flavor to food, oregano also fights viruses and bacteria as one of the best antiviral herbs available. During an infection, oregano essential oil (high quality only) can be taken in a capsule to speed healing. If using oregano essential oil topically, use a carrier oil to prevent skin irritation.
How to Use Antibacterial and Antiviral Herbs
Tea
Herbal teas are simple to make and require only a cup, hot water and a way to steep your tea. To make an herbal tea, steep 1 tbsp of antibacterial or antiviral herbs in 1 cup hot water for 5-10 minutes. For children, use 1 tsp herbs in the same amount of water.
Infusion
Herbal infusions are simply antibacterial or antiviral herbs prepared in water. They differ from teas in that they use larger quantities of herbs, making a more concentrated preparation. They are steeped in water for several hours in a tightly sealed jar. Using a quart-size canning jar is best because they can hold up well to boiling water.
Once prepared you can drink them iced or heated, add them to baths for soaking wounds or sore muscles or used to make compresses or poultices.
Put a handful of dried herbs in your canning jar. Fill the jar to the fill line with boiling water. Secure the lid tightly and let it steep until the water has completely cooled. Strain out the antibacterial or antiviral herbs and enjoy.
Infused oil
Creating your own infused oil is easy! You can do it with just a few minutes of prep time (the rest is done in the oven).
You'll need:
An oven-proof dish
Fine mesh strainer or cheesecloth
1 cup jojoba or coconut oil
1/2 cup antibacterial or antiviral herbs (one herb or a combination)
Clean, dry jar(s) to store your oil in
Labels
Heat your oven to 200 degrees, then turn it off. To your oven-proof dish, add the oil and herbs, then stir them together. (If the coconut oil is solid, let it melt first in the oven, add the herbs and stir). Put the dish in the oven. After 3 hours take out the herbs and strain the oil into your clean jar(s). Label and store in a cool, dark place.
(Infused oils are different from essential oils. Learn more about essential oils here.)

Clove www.drugs.com/npp/clove.html
Scientific Name(s): Eugenia caryophyllata
Common Name(s): Clove , caryophyllus
www.plantguide.org/_images/clove.jpg
Uses of Clove
Clove has been used for its antiseptic and analgesic effects and has been studied for use as an anticoagulant and anti-inflammatory effects. However, research reveals little or no clinical data on the use of clove for any indication.
Botany
The clove plant grows in warm climates and is cultivated commercially in Tanzania, Sumatra, the Maluku (Molucca) Islands, and South America. The tall evergreen plant grows up to 20 m and has leathery leaves. The clove spice is the dried flower bud. Essential oils are obtained from the buds, stems, and leaves. The buds or cloves are strongly aromatic
History
Clove has a long history of culinary and medicinal use. The oil was used as an expectorant and antiemetic with inconsistent clinical results. Clove tea was used to relieve nausea. Use of the oil in dentistry as an analgesic and local antiseptic continues today. It also has been used topically as a counterirritant.
Chemistry
Clove buds yield approximately 15% to 20% of a volatile oil that is responsible for the characteristic smell and flavor. The bud also contains a tannin complex, a gum and resin, and a number of glucosides of sterols. The principal constituent of distilled clove bud oil (60% to 90%) is eugenol (4-allyl-2-methoxyphenol). The oil also contains about 10% acetyleugenol and small quantities of gallic acid, sesquiterpenes, furfural, vanillin, and methyl-n-amyl ketone. Other constituents include flavonoids, carbohydrates, lipids, oleanolic acid, rhamnetin, and vitamins.
Clove oil is applied for the symptomatic treatment of toothaches and is used for the treatment of dry socket (postextraction alveolitis).
Clove oil is reported to have antihistaminic and antispasmotic properties, most likely due to the presence of eugenyl acetate. Cloves are also said to have a positive effect on healing stomach ulcers. A 15% tincture of cloves is effective in treating topical fungal, ringworm infections. As with many other volatile oils, clove oil inhibits gram-positive and gram-negative bacteria. Clove oil also has anthelminthic properties.
Cinnamon www.drugs.com/npp/cinnamon.html
Scientific Name(s): Cinnamomum verum, C. cassia, C. zeylanicum, C. loureirii.
Common Name(s): Cinnamon, cinnamomon, ceylon cinnamon, Chinese cinnamon, Chinese cassia, Saigon cinnamon
unitproj1.library.ucla.edu/biomed/spice/images/historical_CINNAMON.jpg
Uses of Cinnamon
Cinnamon is used as a spice and an aromatic. The bark or oil has been used to combat microorganisms, diarrhea and other GI disorders, and dysmenorrhea. Research interest has focused on cinnamon's potential as an insulin-like analog, an anti-inflammatory agent, an antioxidant, and an antimicrobial substance.
Botany
Cinnamon spice is derived from the brown bark of the tree by grinding the bark into a fine powder. The plant is native to Sri Lanka, southeastern India, Indonesia, South America, and the West Indies.
Chemistry
The essential oil is primarily composed of 65% to 80% cinnamaldehyde and lesser amounts of other phenols and terpenes, including eugenol, trans-cinnamic acid, hydroxycinnamaldehyde, o-methoxycinnamaldehyde, cinnamyl alcohol and its acetate, limonene, α-terpineol, tannins, mucilage, oligomeric procyanidins, and trace amounts of coumarin. Differing material origins and extraction techniques are reported to alter the chemical composition of the extracts, and hence may impact the intended medicinal (and experimental) effects.
Antimicrobial activity
Conflicting evidence exists for the action of cinnamon on Helicobacter pylori . Cinnamon extracts have been shown to exert in vitro activity against some common human pathogens and fungicidal activity against plant pathogens. In vitro inhibition of bacterial endotoxin has been demonstrated by an unidentified component in cinnamon bark. The essential oils of cinnamon were shown to halt mycelial growth and aflatoxin synthesis in Aspergillus parasiticus at a concentration of only 0.1%.
Nutmeg www.drugs.com/npp/nutmeg.html
Scientific Name(s): Myristica fragrans
Common Name(s): Nutmeg, mace, magic, muscdier, nux moschata, myristica oil, muskatbaum
www.herbdatanz.com/Nutmeg.gif
Uses of Nutmeg
Nutmeg and mace, widely accepted as flavoring agents, are used in higher doses for their aphrodisiac and psychoactive properties.
Botany
Mace and nutmeg are 2 slightly different flavored spices, both originating from the fruit of the nutmeg tree, Myristica fragrans . This slow-growing evergreen grows to more than 20 m and is cultivated in India, Ceylon, Malaysia, and Granada. The fruit, which is called a drupe or a nutmeg apple, is similar in appearance to a peach or an apricot. When the mature fruit splits open, the nutmeg (stony endocarp or seed surrounded by a red, slightly fleshy network or aril) is exposed. The dried aril alone is called mace. The nut is removed and dried to produce nutmeg.
History
Nutmeg is a widely used food spice that has received attention as an alternative hallucinogen. Nutmeg and mace have been used in Indian cooking and folk medicine. The folk uses of nutmeg have included the treatment of gastric disorders and rheumatism, and it has been used as a hypnotic and an aphrodisiac. During the 6th century AD, nutmeg and mace were imported by Arab traders. By the 12th century, these spices were well known in Europe. At the turn of the 19th century, interest developed in the use of nutmeg as an abortifacient and a stimulant for menses. These properties have been largely discounted but remain a persistent cause of nutmeg intoxication in women.
Chemistry
Nutmeg seeds contain 20% to 40% of a fixed oil, commonly called nutmeg butter. This oil contains myristic acid, trymiristin, and glycerides of lauric, tridecanoic, stearic, and palmitic acids.
Nutmeg also yields 8% to 15% of an essential oil that is believed to be partially responsible for the effects associated with nutmeg intoxication. The essential oil contains myristicin, elemicin, eugenol, and safrole. The essential oils of nutmeg and mace are very similar in chemical composition and aroma, with wide color differences (brilliant orange to pale yellow). Mace oil appears to have a higher myristicin content than nutmeg oil.
Also present in the oil are sabinene, cymene alpha-thujene, gamma-terpinene, and monoterpene alcohols in smaller amounts. Phenolic compounds found in nutmeg are reported to have antioxidant properties. Other isolated compounds include the resorcinols malabaricone B and malabaricone C, as well as lignans and neolignans.
Antimicrobial effects
The oils of mace and nutmeg and their individual components have been assessed for their antimicrobial activity in vitro. Activity has been shown against some oral microorganisms, including S. mutans, Porphyromonas gingivalis , and others. Activity against other bacteria includes some strains of Escherichia coli, some strains of Salmonella typhi, Bacillus subtilis, Staphylococcus aureus, and Listeria monocytogenes. Anti-viral effect has also been reported against human rotavirus.
Reports of activity against fungi is conflicting, with no activity against Aspergillus but activity against some dermatophytes has been found.
===============================================
The spices cloves, nutmeg, cinnamon, bay leaves contain eugenol, a clear to pale yellow oily liquid with a pleasant, spicy, clove-like odor, that can be extracted from the essential oils from these plants.
Eugenol
Eugenol is used in perfumeries, flavorings, essential oils and in medicine as a local antiseptic and anaesthetic. Combining zinc oxide and eugenol forms zinc oxide eugenol which can be used as a filling or cement material used in dentistry. It is classified as an intermediate restorative material and has anaesthetic and antibacterial properties. It is sometimes used in the management of dental caries as a "temporary filling".

Oregano www.drugs.com/npp/oregano.html
Scientific Name(s): Origanum vulgare
Common Name(s): Mediterranean oregano, mountain mint, wild marjoram, winter marjoram, wintersweet
www.yankeegardener.com/seeds/herb-oregano-lg.jpg
Uses of Oregano
Aside from its culinary application, oregano exhibits antimicrobial and antioxidant actions and has possible activity as an antispasmodic and in diabetes. However, there is no clinical evidence to support the use of oregano in any indication.
Botany
Common or wild oregano is a perennial plant native to the Mediterranean region and Asia and cultivated in the United States. Its creeping rootstock produces a square, downy, purplish stem with opposite ovate leaves. Stems can grow up to 76 cm tall and are dotted with small depressions. Purple, 2-lipped flowers grow in terminal clusters from July to October.
History
Oregano has been a common ingredient in Spanish, Mexican, and Italian dishes as a spice and flavoring agent for hundreds of years. Its initial purpose was as a warming digestive and circulatory stimulant. It has been used in perfumery for its volatile oil contents, especially in scenting soaps.
The antiseptic qualities of aromatic and medicinal plants and their extracts have been recognized since antiquity. It has been suggested that an infusion of the fresh herb is beneficial in treating an upset stomach and indigestion, headache, colic, and nervous complaints, as well as for coughs and other respiratory ailments. An infusion of the flowers has been used to prevent seasickness. The oil has been used externally in liniments and lotions and to ease toothache. It has also been used as an ant repellent.
Chemistry
Oregano contains oleanolic and ursolic acids, flavonoids and hydroquinones, caffeic, rosemarinic, and lithospermic acid, tannins, and phenolic glycosides. Phenolic compounds represent 71% of the total oil. The polar phenols thymol and carvacrol are responsible for many of the properties of the essential oil, as well as p-cymene and terpinene.
Antimicrobial activity
Studies have compared the effects of oregano essential oil, thymol, and carvacrol on fungi. All 3 completely inhibited fungal growth of Aspergillus and Penicillium species. Oregano oil also appears to have some activity against Candida species, possibly because of its carvacrol content.
The volatile oils of oregano have demonstrated in vitro antibacterial activity against a wide range of gram-positive and gram-negative microorganisms including Listeria, Pseudomonas, Proteus, Salmonella, and Clostridium species, as well as some methicillin-resistant Staphylococci. Low to moderate activity against Helicobacter pylori has been reported. Oregano oil appears to inhibit organisms at relatively low concentrations, and its activity could be due to the phenolic components thymol and carvacrol.
There are also various reports describing antiparasitic activity of oregano.
The oil of Origanum vulgare has been shown to eradicate common parasites in chickens and pheasants. In vitro experiments have shown activity against Trypanosoma cruzi.
========================================
The spices oregano and thyme contain Thymol (and a closely related substance called carvacrol), which have been shown to possess bacteriocidal, fungicidal, molluscicidal and insecticidal properties.
C10H14O Thymol
The main therapeutic application for thymol is in dental preparations to kill odor-producing bacteria. It is also employed as a preservative on the strength of its antimicrobial and antioxidant properties. In the mollusc Lymnaea acuminata, lethal doses of thymol affected the activity of key nervous tissue enzymes, and this was postulated to be the cause of toxicity As yet, no mechanism of action has been identified for thymol lethality, or that of related monoterpenoids, towards insects.
Recently, thymol was shown to have a direct agonist effect on heterologously expressed human GABAA receptors resembling that of the anaesthetic propofol.
The active ingredients of Listerine include essential oils (thymol, eucalyptol, menthol, methyl salicylate) with anti-fungal activity. This early ad for Listerine recommends its use for treating dandruff.

Onion www.drugs.com/npp/onion.html
Scientific Name(s): Allium cepa
Common Name(s): Onion
aggie-horticulture.tamu.edu/extension/vegetable/cropguides/pictures/onion.jpg
Uses of Onion
Onion is used as an antimicrobial, cardiovascular-supportive, hypoglycemic, antioxidant/anticancer, and asthma-protective agent. However, few clinical trials are available to support the use of onion for any indication. In folk medicine, onion has been used for asthma, bronchitis, whooping cough, and similar ailments. Other uses include the treatment of stingray wounds, warts, acne, appetite loss, urinary tract disorders, and indigestion. Onion skin dye has been used as an egg and cloth coloring.
Botany
The onion plant is a perennial herb growing to about 1.2 m, with 4 to 6 hollow, cylindrical leaves. On top of the long stalk, greenish-white flowers are present in the form of solitary umbels growing up to 2.5 cm wide. The seeds of the plant are black and angular. The underground bulb, which is used medicinally, is comprised of fleshy leaf sheaths forming a thin-skinned capsule. The onion is one of the leading vegetable crops in the world.
History
The onion is believed to have been domesticated in central Asia. Onions were used as early as 5,000 years ago in Egypt, as depicted on ancient monuments; ancient Greek and Roman records also refer to the onion. During the Middle Ages, onions were consumed throughout Europe. They later were thought to guard against evil spirits and the plague, probably because of their strong odor. Onion skin dye has been used for egg and cloth coloring for many years in the Middle East and Europe. Columbus was said to have brought the onion to America. Folk healers used the onion to prevent infection. The combination of onions and garlic cooked in milk is a European folk remedy used to clear congestion. Onions also are used in homeopathic medicine.
Chemistry
Onions contain 89% water, 1.5% protein, and vitamins, including B1 , B2 , and C, along with potassium. Polysaccharides such as fructosans, saccharose, and others are also present, as are peptides, flavonoids, and essential oil. Onion contains alliin and similar sulfur compounds, including allylalliin and methyl and propyl compounds of cysteine sulfoxide. Sulfur and other compounds of A. cepa have been analyzed. Prostaglandins also have been identified in onion.
Antimicrobial effects
Onion has reported antibacterial, antiparasitic, and antifungal actions. Growth of oral pathogenic bacteria, including Streptococcus mutans, Porphyromonas gingivalis, and Prevotella intermedia, organisms associated with dental caries and periodontitis, was prevented by onion extracts. Onion juice or oil also have inhibited growth of other gram-positive bacteria and gram-negative bacteria such as Klebsiella pneumoniae. Antifungal actions of onion include inhibition of yeasts and a number of molds.
The antibacterial, antiparasitic, and antifungal actions of onion is believed to be due to a number of sulfur containing compounds such as alliin, allylalliin, diallyl disulfide and the methyl and propyl compounds of cysteine sulfoxide.
Onions are also noted for their ability to make you cry. This effect is due to one of these propyl sulfoxides which is converted to propanethial-S-oxide which then escapes from the onion in vapor form and hydrolyzes to sulfuric acid when it reacts with moisture, causing the familiar eye irritation and lacrimation.

The health promoting reputation of onions is legendary and may be due to other compounds found in the bulb. For instance, prostaglandins, which have profound physiological effects in animals, also have been reported to exist in onion. (Al-Nagdy S, Abdel Rahman MO, Heiba HI. Comp Biochem Physiol C . 1986;85:163-166).
Garlic www.drugs.com/npp/garlic.html
Scientific Name(s): Allium sativum
Common Name(s): Garlic, allium, stinking rose, rustic treacle, nectar of the gods, camphor of the poor, poor man's treacle
www.designmom.com/uploaded_images/cj4.garlic1-742608.jpg
Uses of Garlic
Evidence suggests that garlic may beneficially affect cholesterol and lipids. Among its traditional uses, it has been employed for its antiseptic and antibacterial properties. Other potential areas of use include GI disorders and oncology.
Botany
A perennial bulb with a tall, erect flowering stem that grows to 2 to 3 feet. The plant produces pink to purple flowers that bloom from July to September. The bulb is odiferous.
History
The name Allium comes from the Celtic word all meaning burning or smarting. Garlic was valued as an exchange medium in ancient Egypt; its virtues were described in inscriptions on the Great Pyramid of Cheops. The folk uses of garlic have ranged from the treatment of leprosy in humans to managing clotting disorders in horses. Physicians prescribed the herb during the Middle Ages to cure deafness and the American Indians used garlic as a remedy for earaches, flatulence, and scurvy.
Chemistry
Fresh garlic is a source of numerous vitamins, minerals, and trace elements, although most are only found in minute quantities. Garlic contains the highest sulfur content of any member of the genus Allium. Two trace elements, germanium and selenium, are found in detectable quantities and have been postulated to play a role in the herb's antitumor effect.
Garlic contains about 0.5% of a volatile oil composed of sulfur-containing compounds (diallyldisulfide, diallyltrisulfide, methylallyltrisulfide). The bulbs contain an odorless, colorless, sulfur-containing amino acid called alliin (S-allyl-L-cysteine sulfoxide), which has no known pharmacologic activity. When the bulb is ground, the enzyme allinase is released, resulting in the conversion of alliin to 2-propenesulfenic acid, which dimerizes to form allicin. Allicin gives the pungent characteristic odor to crushed garlic and is believed to be responsible for some of the pharmacologic activity of the plant.
Uses of Garlic
Evidence suggests that garlic may beneficially affect cholesterol and lipids. Among its traditional uses, it has been employed for its antiseptic and antibacterial properties. Other potential areas of use include GI disorders and oncology.
Antiseptic/Antibacterial properties
The antiseptic and antibacterial properties of garlic have been known for centuries. As recently as World War II, garlic extracts were used to disinfect wounds. During the 1800s, physicians routinely prescribed garlic inhalation for the treatment of tuberculosis.
Garlic extracts inhibit the growth of numerous strains of Mycobacterium, but at concentrations that may be difficult to achieve in human tissues. Preparations containing garlic extracts are used widely in Russia and Japan. Both gram-positive and gram-negative organisms are inhibited in vitro by garlic extracts. The potency of garlic is such that 1 mg is equivalent to 15 Oxford units of penicillin, making garlic about 1% as active as penicillin.
Garlic extracts have shown antifungal activity when tested in vitro and their use has been suggested in the treatment of oral and vaginal candidiasis. In an attempt to quantitate the in vivo activity of garlic extracts, one research group administered 25 mL of fresh garlic extract orally to volunteers. Serum and urine samples were tested for antifungal activity against 15 species of fungal pathogens. While serum exhibited anticandidal and anticryptococcal activity within 30 minutes after ingestion, no biological activity was found in urine. The findings suggest that while garlic extracts may exhibit some antifungal activity in vivo, they are probably of limited use in the treatment of systemic infections.
Anise www.drugs.com/npp/anise.html
Scientific Name(s): Pimpinella anisum
Common Name(s): Anise, aniseed, sweet cumin
unitproj1.library.ucla.edu/biomed/spice/images/historical_ANISE.jpg
Uses of Anise
Anise is used as a flavoring in alcohols, liqueurs, dairy products, gelatins, puddings, meats, and candies, and as a scent in perfumes, soaps, and sachets. The oil has also been used to treat lice, scabies, and psoriasis. Anise frequently is used as a carminative and expectorant. Anise also is used to decrease bloating and settle the digestive tract in children. In high doses, it is used as an antispasmodic and an antiseptic and for the treatment of cough, asthma, and bronchitis. However, research reveals no clinical data regarding the use of anise for any of these applications.
History
Anise has a history of use as a spice and a fragrance. It has been cultivated in Egypt for at least 4,000 years. Records of its use as a diuretic and treatment of digestive problems and toothache are seen in medical texts from this era. In ancient Greek history, writings explain how anise helps breathing, relieves pain, stimulates urination, and eases thirst. The essential oil has been used commercially since the 1800s. The fragrance is used in food, soap, creams, and perfumes. Anise often is added to licorice candy or used as a �licorice� flavor substitute; it is also a fragrant component of anisette liqueur.
Chemistry
Anise oil (1% to 4%) is obtained by steam distillation of the dried fruits of the herb. The highest quality oils result from anise seeds of ripe umbels in the center of the plant. A major component of the oil is trans-anethole (75% to 90%), responsible for the characteristic taste and smell, as well as for its medicinal properties.
The volatile oil also has related compounds that include estragole (methyl chavicol, 1% to 2%), anise ketone (p-methoxyphenylacetone), and beta caryophyllene. In smaller amounts are anisaldehyde, anisic acid, limonene, alpha-pinene, acetaldehyde, p-cresol, cresol, and myristicin (the psychomimetic compound previously isolated from nutmeg).
Constituents of the whole seed include coumarins, such as umbelliferone, umbelliprenine, bergapten, and scopoletin. Lipids (16%) include fatty acids, beta-amyrin, stigmasterol, and its salts. Flavonoids in aniseed include rutin, isoorientin, and isovitexin. Protein (18%) and carbohydrate (50%) are also present. Terpene hydrocarbons in the plant also have been described.
Antimicrobial
Anise has been evaluated for its antimicrobial action against gram-negative and gram-positive bacteria and also a few fungi. Anise is used in dentifrices as an antiseptic and in lozenges and cough preparations for its weak antibacterial effects.
Sassafras www.drugs.com/npp/sassafras.html
Scientific Name(s): Sassafras albidum
Common Name(s): Sassafras, saxifras, ague tree, cinnamon wood, saloop
pictopia.com/perl/get_image?provider_id=262&size=550x550_mb&ptp_photo_id=1796302
Uses of Sassafras
Sassafras has been used historically for a variety of illnesses, and is now banned in the US, even for use as a flavoring or fragrance.
Botany
Sassafras is the name applied to three species of trees, two native to eastern Asia and one native to eastern North America. Fossils show that sassafras was once widespread in Europe, North America and Greenland. The trees grow up to 100 feet in height and 6 feet in diameter, though they are usually smaller. Sassafras bears leaves 10 to 15 cm long that are oval on older branches but mitten-shaped or three-lobed on younger shoots and twigs. All parts of the tree are strongly aromatic. The drug is from the peeled root of the plant (root bark).
History
Native Americans have used sassafras for centuries and told early settlers that it would cure a variety of ills. The settlers then exported it to Europe, where it was found to be ineffective.
Over the years the oil obtained from the roots and wood has been used as a scent in perfumes and soaps. The leaves and pith, when dried and powdered, have been used as a thickener in soups. The roots are often dried and steeped for tea, and sassafras was formerly used as a flavoring in root beer. Its use as a drug or food product has been banned by the US Food and Drug Administration (FDA) as carcinogenic; however, its use and sale persist throughout the United States. Medicinally, sassafras has been applied to insect bites and stings to relieve symptoms.
Chemistry
The main constituent of sassafras oil is safrole, which chemically is p-allyl-methylenedioxybenzene, which comprises up to 80% of the oil. Volatile oil also contains anethole, pinene apiole, camphor, eugenol and myristicin.
The plant contains less than 0.2% total alkaloids (primarily boldine and its derivatives and reticuline) along with tannins, resins, mucilage and wax. Six alkaloids, aporphine and benzylsoquinoline derivatives, have been found in root bark. Two antimicrobial neolignans, magnolol and its related isomer (isomagnolol), from related species S. randaiensis have been isolated.
Sassafras Uses and Pharmacology
Sassafras has been used as a sudorific agent, a flavoring agent for dentifrices, root beers and tobaccos, and for treatment of eye inflammation. Extracts of the roots and bark have been found to mimic insect juvenile hormone in Oncopeltus fasciatus. The oil has been applied externally for relief of insect bites and stings and for lice. Other external uses include treatment of rheumatism, gout, sprains, swelling and cutaneous eruptions. A recent report compares safrole (the main constituent from sassafras oil), to indomethacin for anti-inflammatory activity and pain treatment in mice.
The plant has been reported to have antineoplastic activity and to induce cytochrome P-488 and P-450 enzymes. Sassafras is said to be antagonistic to certain alcohol effects. Alcohol extracts of the related S. randaiense exhibit antimicrobial and antifungal activity in vitro, and this activity appears to be due to the presence of magnolol and isomagnolol.
Noni www.drugs.com/npp/noni.html
Scientific Name(s): Morinda citrifolia
Common Name(s): Morinda, noni, hog apple, Indian mulberry, mengkoedoe, mora de la India, pain killer, ruibarbo caribe, wild pine
www.nannisnoni.com/High%20Res%20Noni.jpg
Uses of Noni
Morinda has been used for heart remedies, arthritis, headache, digestive and liver ailments.
Botany
The morinda plant, native to Asia, Australia and Polynesia, is a 3 to 8 m high tree or shrub. Its evergreen leaves are oblong and 10 to 45 cm in length. The plant's white flowers are tubular, with conelike heads. The fruit is yellow-white in color, oval in shape, about the size of a potato and has a �bumpy� surface. The ripened fruit has a characteristic cheese-like, offensive odor. Each fruit contains 4 seeds, 3 mm in length.
History
It is believed that Polynesian healers have used morinda fruits for thousands of years to help treat a variety of health problems such as diabetes, high blood pressure, arthritis and aging. Ancient healing manuscripts cite the fruit as a primary ingredient in natural healing formulations. Today, fruit preparations are sold as juice, in dried �fruit-leather� form and as a dry extract in capsules.
Chemistry
Morinda citrifolia fruits contain essential oils with hexoic and octoic acids, paraffin and esters of ethyl and methyl alcohols. Ripe fruit contains n-caproic acid, presumably responsible for its distinctive odor, known to attract insects such as Drosophilia sechellia. Fresh plants contain anthraquinones, morindone and alizarin. A new anthraquinone glycoside from morinda heartwood has recently been described. Hawaiian researcher Ralph Heinicke discovered a small plant alkaloid he termed �xeronine.� Damnacanthal, morindone and alizarin are present in cell suspension cultures.
Noni Uses
Morinda citrifolia has been used medicinally for heart remedies, arthritis (by wrapping the leaves around affected joints), headache (local application of leaves on forehead), GI and liver ailments.
Alcoholic extracts of M. citrifolia leaves displayed good anthelmintic activity in vitro against the human parasite Ascaris lumbricoides . Lyophilized aqueous root extracts of the plant showed central analgesic activity, among other effects, suggesting sedative properties of the plant as well.
Wintergreen www.drugs.com/npp/wintergreen.html
Scientific Name(s): Gaultheria procumbens
Common Name(s): Wintergreen, teaberry, checkerberry, gaultheria oil, boxberry, deerberry, mountain tea, Canada tea, partridgeberry
members.tripod.com/~Elspeth_Stormdancer/Herbs/Herblist/herbpix/wintergreen.gif
Uses of Wintergreen
In addition to being used as a flavoring, wintergreen and its oil have been used in topical analgesic and rubefacient preparations for the treatment of muscular and rheumatic pain. However, research reveals no clinical data regarding the use of wintergreen for any condition.
Botany
Wintergreen is a perennial evergreen shrub with thin, creeping stems from which leathery leaves with toothed, bristly margins arise. It is a low-growing plant native to eastern North America and usually is found in woodland and exposed mountainous areas. Its small, waxy, white or pale pink flowers bloom in late summer, developing a scarlet fruit. The aromatic leaves and fruits are edible.
History
American Indians reportedly used wintergreen for treating back pain, rheumatism, fever, headaches, and sore throats. The plant and its oil have been used in traditional medicine as an anodyne, analgesic, carminative, astringent, and topical rubefacient.
Wintergreen oil is obtained by steam distillation of the warmed, water-macerated leaves. It is used interchangeably with sweet birch oil or methyl salicylate for flavoring foods and candies. The highest amount of methyl salicylate typically used in candy flavoring is 0.04%.
Wintergreen berries have been used to make pies. A tea made from the leaves was used as a substitute for black tea, Camellia sinensis, during the Revolutionary War. Wintergreen tea has been used to relieve cold symptoms and muscle aches.
Chemistry
Wintergreen oil contains approximately 98% to 100.5% of the methyl ester, methyl salicylate. The plant has little odor or flavor until the methyl salicylate is freed. During steam distillation, the gaultherin (also described as primeveroside or monotropitoside) present in the leaves is enzymatically hydrolyzed to methyl salicylate. The purified methyl salicylate is subsequently obtained through distillation. In addition, the sugars D-glucose and D-xylose are obtained. The yield of oil from the leaves is in the range of 0.5% to 0.8%.

Ginger www.drugs.com/npp/ginger.html
Scientific Name(s): Zingiber officinale Roscoe; occasionally Z. capitatum
Common Name(s): Ginger, ginger root, black ginger, zingiberis rhizoma
www.botanical.com/botanical/mgmh/g/ginger13-l.jpg
Uses of Ginger
Ginger and its constituents have antiemetic, cardiotonic, antithrombotic, antibacterial, antioxidant, antitussive, antihepatotoxic, anti-inflammatory, antimutagenic, stimulant, diaphoretic, diuretic, spasmolytic, immunostimulant, carminative, and cholagogue actions. Ginger is used to promote gastric secretions, increase intestinal peristalsis, lower cholesterol levels, raise blood glucose, and stimulate peripheral circulation. Traditionally used to stimulate digestion, its modern uses include prophylaxis for nausea and vomiting (associated with motion sickness, hypermesis gravidarum, and anesthesia), dyspepsia, lack of appetite, anorexia, colic, bronchitis, and rheumatic complaints. Ginger can be used as a flavoring or spice as well as a fungicide and pesticide.
Botany
A native of tropical Asia, this perennial is cultivated in tropical climates such as Australia, Brazil, China, India, Jamaica, West Africa, and parts of the US. The rhizome is used medicinally and as a culinary spice. The rhizome is harvested between 6 and 20 months; taste and pungency increase with maturity. The plant carries a green-purple flower in terminal spikes; the flowers are similar to orchids.
History
Medicinal use of ginger dates back to ancient China and India; references to its use are found in Chinese pharmacopoeias, the Sesruta scriptures of Ayurvedic medicine as well as Sanskrit writings. Once its culinary properties were discovered in the 13th century, use of this herb became widespread throughout Europe. In the Middle Ages, it held a firm place in apothecaries for travel sickness, nausea, hangovers, and flatulence.
Ginger and its constituents are stated to have antiemetic, cardiotonic, antithrombotic, antibacterial, antioxidant, antitussive, antihepatotoxic, anti-inflammatory, antimutagenic, stimulant, diaphoretic, diuretic, spasmolytic, immunostimulant, carminative, and cholagogue actions as well as to promote gastric secretions, increase intestinal peristalsis, lower cholesterol levels, raise blood glucose, and stimulate peripheral circulation. Traditionally, ginger is used as an acrid bitter to strengthen and stimulate digestion. Modern uses include prophylaxis for nausea and vomiting (associated with motion sickness, hyperemesis gravidarum and surgical anesthesia), dyspepsia, lack of appetite, anorexia, colic, bronchitis, and rheumatic complaints. The food industry uses ginger oil as a spice and ginger extract in the manufacturing of ginger ale. In China, ginger root and stem are used as pesticides against aphids and fungal spores.
Ginger is in the official pharmacopoeias of Austria, China, Egypt, Great Britain, India, Japan, the Netherlands, and Switzerland. It is approved as a nonprescription drug in Germany and as a dietary supplement in the US.
Chemistry
It had long been believed that the �pungent principles� of ginger were also responsible for its pharmacologic activity, and this has been found to be accurate. The characteristic aroma of ginger is due mainly to the presence of zingiberol in the volatile oil.
The major constituents in ginger rhizomes are carbohydrates (50 to 70%), which are present as starch. The concentration of lipids is 3 to 8% and includes free fatty acids (eg, palmitic, oleic, linoleic, linolenic, capric, lauric, myristic), triglycerides, and lecithins. Oleoresin provides 4 to 7.5% of pungent substances as gingerol homologues, shogaol homologues, zingerone, and volatile oils. Volatile oils are present in 1 to 3% concentrations and consist mainly of the sesquiterpenes beta-besabolene and zingiberene; other sesquiterpenes include zingiberol and zingiberenol; numerous monoterpenes are also found. Amino acids, raw fiber, ash, protein, phytosterols, vitamins (ie, nicotinic acid and vitamin A), and minerals are among the other constituents.
Analyses of the oleoresins have resulted in the identification of a class of structurally related cardiotonic compounds called gingerols, which upon dehydration, form shogaols and degrade further to zingerone. [6]-gingerol and [6]-shogaol are the main components however, the pharmacologically active compounds [6]- and [10]-dehydrogingerdione, and [6]- and [10]-gingerdione have also been identified.
Ginger Uses
Human clinical trials have examined ginger's antiemetic effects related to kinetosis (motion sickness), perioperative anesthesia, and hyperemesis gravidarum. However, little is still known regarding its human pharmacology in these settings. Animal studies have described enhanced GI transport as well as anti-5-hydroxytryptamine (5HT 3 ) and possible CNS antiemetic effects.
Ginger has been reported to have weak fungicidal, strong antibacterial, and anthelmintic properties. Active constituents have been shown to inhibit reproduction of Escherichia coli, Proteus species, Staphylococci, Streptococci, and Salmonella but to stimulate the growth of Lactobacilli. In vitro anthelmintic activity has been documented for the volatile oil of Z. purpureum and activity has also been reported against parasites, such as Schistosoma and Anisakis.
The cytotoxic compound zerumbone and its epoxide have been isolated from the rhizomes of Z. zerumbet . This plant, also a member of the family Zingiberaceae, has been used traditionally in China as an antineoplastic.
