DETAILED DESACRIPTION
Ginger is the rhizome of the plant Zingiber officinale, consumed whole as a delicacy, medicine, or spice. It lends its name to its genus and family (Zingiberaceae). Other notable members of this plant family are turmeric, cardamom, and galangal.
Ginger cultivation began in South Asia and has since spread to East Africa and the Caribbean.[2] It is sometimes called root ginger to distinguish it from other things that share the name ginger.

Chemistry
The characteristic odor and flavor of ginger is caused by a mixture of zingerone, shogaols and gingerols, volatile oils that compose one to three percent of the weight of fresh ginger. In laboratory animals, the gingerrols increase the motility of the gastrointestinal tract and have analgesic, sedative, antipyretic and antibacterial properties.[3] Ginger oil has been shown to prevent skin cancer in mice[4] and a study at the University of Michigan demonstrated that gingerols can kill ovarian cancer cells.[5],[6],[7]6]-gingerol (1-[4'-hydroxy-3'-methoxyphenyl]-5-hydroxy-3-decanone) is the major pungent principle of ginger, the chemopreventive potentials of [6]-gingerol present a promising future alternative to expensive and toxic therapeutic agents [8]
Ginger contains up to three percent of a fragrant essential oil whose main constituents are sesquiterpenoids, with (-)-zingiberene as the main component. Smaller amounts of other sesquiterpenoids (β-sesquiphellandrene, bisabolene and farnesene) and a small monoterpenoid fraction (β-phelladrene, cineol, and citral) have also been identified.
The pungent taste of ginger is due to nonvolatile phenylpropanoid-derived compounds, particularly gingerols and shogaols, which form from gingerols when ginger is dried or cooked. Zingerone is also produced from gingerols during this process; this compound is less pungent and has a spicy-sweet aroma.[9] Ginger is also a minor chemical irritant, and because of this was used as a horse suppository by pre-World War I mounted regiments for feaguing.
Ginger has a sialagogue action, stimulating the production of saliva, which makes swallowing easier.
Uses
Culinary use
Young ginger rhizomes are juicy and fleshy with a very mild taste. They are often pickled in vinegar or sherry as a snack or just cooked as an ingredient in many dishes. They can also be steeped in boiling water to make ginger tea, to which honey is often added; sliced orange or lemon fruit may also be added. Ginger can also be made into candy.
Mature ginger roots are fibrous and nearly dry. The juice from old ginger roots is extremely potent,[citation needed] and is often used as a spice in Indian recipes, and is a quintessential ingredient of Chinese, Japanese and many South Asian cuisines for flavoring dishes such as seafood or goat meat and vegetarian cuisine.
Ginger acts as a useful food preservative.[10]
Fresh ginger can be substituted for ground ginger at a ratio of 6 to 1, although the flavors of fresh and dried ginger are somewhat different. Powdered dry ginger root is typically used as a flavoring for recipes such as gingerbread, cookies, crackers and cakes, ginger ale, and ginger beer.
Candied ginger is the root cooked in sugar until soft, and is a type of confectionery.
Fresh ginger may be peeled before eating. For longer-term storage, the ginger can be placed in a plastic bag and refrigerated or frozen.
Medicinal use
The medical form of ginger historically was called Jamaica ginger; it was classified as a stimulant and carminative and used frequently for dyspepsia, gastroparesis, slow motility symptoms, constipation, and colic. It was also frequently employed to disguise the taste of medicines. Ginger is on the FDA's "generally recognized as safe" list, though it does interact with some medications, including warfarin. Ginger is contraindicated in people suffering from gallstones as it promotes the production of bile.[11] Ginger may also decrease pain from arthritis, though studies have been inconsistent, and may have blood thinning and cholesterol lowering properties that may make it useful for treating heart disease.[12] An acute overdose of ginger is usually in excess of about 2,000 milligrams per kilogram[13], dependent on level of ginger tolerance, and can result in a state of central nervous system over-stimulation called ginger intoxication or colloquially the "ginger gitters".
Diarrhea
Ginger compounds are active against a form of diarrhea which is the leading cause of infant death in developing countries. Zingerone is likely to be the active constituent against enterotoxigenic Escherichia coli heat-labile enterotoxin-induced diarrhea.[16]
Nausea
Ginger has been found effective in multiple studies for treating nausea caused by seasickness, morning sickness and chemotherapy,[17] though ginger was not found superior over a placebo for pre-emptively treating post-operative nausea. Ginger is a safe remedy for nausea relief during pregnancy.[18] Ginger as a remedy for motion sickness is still a debated issue. The television program Mythbusters performed an experiment using one of their staff who suffered from severe motion sickness. The staff member was placed in a moving device which, without treatment,
Folk medicine
A variety of uses are suggested for ginger. Tea brewed from ginger is a folk remedy for colds. Three to four leaves of tulsi taken with a piece of ginger on an empty stomach is considered an effective cure for congestion, cough and cold.[citation needed] Ginger ale and ginger beer have been recommended as stomach settlers for generations in countries where the beverages are made, and ginger water was commonly used to avoid heat cramps in the United States. In China, "ginger eggs" (scrambled eggs with finely diced ginger root) is a common home remedy for coughing.[citation needed] The Chinese also make a kind of dried ginger candy that is fermented in plum juice and sugared, which is also commonly consumed to suppress coughing. Ginger has also been historically used to treat inflammation, which several scientific studies support, though one arthritis trial showed ginger to be no better than a placebo or ibuprofen for treatment of osteoarthritis.[12] Research on rats suggests that ginger may be useful for treating diabetes.[21][22]
Regional medicinal use
In the West, powdered dried ginger root is made into capsules and sold in pharmacies for medicinal use.
• In Burma, ginger and a local sweetener made from palm tree juice (htan nyat) are boiled together and taken to prevent the flu.
• In China, ginger is included in several traditional preparations. A drink made with sliced ginger cooked in water with brown sugar or a cola is used as a folk medicine for the common cold.[23]
• In Congo, ginger is crushed and mixed with mango tree sap to make tangawisi juice, which is considered a panacea.
• In India, ginger is applied as a paste to the temples to relieve headache, and consumed when suffering from the common cold. Ginger with lemon and black salt is also used for nausea.
• In Indonesia, ginger ("jahe" in Indonesian) is used as a herbal preparation to reduce fatigue, reducing "winds" in the blood, prevent and cure rheumatism and control poor dietary habits.
• In the Philippines a traditional health drink called "salabat" is made for breakfast by boiling chopped ginger and adding sugar; it is considered good for a sore throat.
• In the United States, ginger is used to prevent motion and morning sickness. It is recognized as safe by the Food and Drug Administration and is sold as an unregulated dietary supplement.
• In Peru, ginger is sliced in hot water as an infusion for stomach aches as "infusión de Kión"
