'''Ginger ''' is the common name for the [[monocotyledon]]ous [[perennial plant]] ''Zingiber officinale''. The term is also used to describe the edible part of the plant which is commonly used as a [[spice]] in [[cooking]] throughout the world. Often erroneously referred to as "ginger root", the edible section is actually the horizontal subterranean stem or [[rhizome]] of the plant. The ginger plant has a long history of cultivation known originating in China and then to have spread to [[India]], [[Southeast Asia]], [[West Africa]], and the [[Caribbean]].<ref name="origin">{{cite web | url = http://unitproj.library.ucla.edu/biomed/spice/index.cfm?displayID=15 | title = Spices: Exotic Flavours & Medicines: Ginger | accessdate = 2007-08-08 }}</ref>

[[Image:ginger-section.jpg|thumb|left|100px|Ginger section]]
Ginger contains up to 3% of an [[essential oil]] that causes the fragrance of the spice. The main constituents are [[terpene|sesquiterpenoids]] with [[zingiberene|(-)-zingiberene]] as the main component. Lesser amounts of other sesquiterpenoids ([[sesquiphellandrene|β-sesquiphellandrene]], [[bisabolene]] and [[farnesene]]) and a small monoterpenoid fraction ([[phellandrene|β-phelladrene]], [[cineol]], and [[citral]]) have also been identified.
The pungent taste of ginger is due to nonvolatile [[phenylpropanoid]]-derived compounds, particularly [[gingerol]]s and [[shogaol]]s. The latter are formed from the former when ginger is dried or cooked. Zingerone is also produced fron gingerols during this process, and it is less pungent and has a spicy-sweet aroma.<ref name="harold"> [[Harold McGee|McGee, Harold]] (2004).

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 stewed in boiling water to make ginger tea, to which [[honey]] is often added as a sweetener; sliced orange or lemon fruit may also be added. Mature ginger roots are fibrous and nearly dry. The juice from old ginger roots is extremely potent and is often used as a [[spice]] in [[Chinese cuisine]] to [[flavor]] dishes such as [[seafood]] or [[Goat#Meat|mutton]].
Ginger is also made into candy and used as a [[flavoring]] for [[cookie]]s, [[cracker (food)|crackers]] and [[cake]], and is the main flavor in [[ginger ale]]-- a [[sweet]], [[carbonated]], non-[[alcoholic]] [[beverage]], as well as the similar, but somewhat spicier beverage [[ginger beer]]. A ginger-flavored [[liqueur]] called [[Canton (liqueur)|Canton]] is produced in [[Jarnac]], [[France]]. Green [[ginger wine]] is a ginger flavoured wine produced in the [[United Kingdom]] by [[Crabbie's]] and Stone's and traditionally sold in a green glass bottle. Ginger is also used as a [[spice]] added to hot [[coffee]] and [[tea]].
In [[Arabic]], ginger is called ''Zanjabil'' and in some parts of the [[Middle East]] ginger powder is used as a spice for coffee.
In [[India]], ginger is called "Shoonti" in Kannada language[Karnataka], ''Allam '' in [[Telugu language|Telugu]], ''Inji'' in [[Tamil language|Tamil]] and [[Malayalam]], ''Alay'' in [[Marathi]] and ''Adrak'' in [[Hindi]] and [[Urdu]]. Fresh ginger is one of the main spices used for making pulse and lentil curries and other vegetable preparations. It is used fresh to spice tea especially in winter. Also, ginger powder is used in certain food preparations that are made particularly for expecting women and feeding mothers, the most popular one being ''Katlu'' which is a mixture of gum resin, [[ghee]], nuts and sugar.
In south India, ginger is used in the production of a candy called Inji-murappa ("ginger candy" from Tamil). This candy is mostly sold by vendors to bus passengers in bus stops and in small tea shops as a locally produced item. Candied ginger is also very famous around these parts. Additionally, in [[Tamil Nadu]], especially in the Tanjore belt, a variety of ginger which is less spicy is used when tender to make fresh pickle with the combination of lemon juice or vinegar, salt and tender green chillies. This kind of pickle was generally made before the invention of refrigeration and stored for a maximum of 4-5 days. The pickle gains a mature flavor when the juices cook the ginger over the first 24 hours. Ginger is also added as a flavouring in [[tea]].
In [[Japan]], ginger is pickled to make [[beni shoga]] and [[Gari (ginger)|gari]] or grated and used raw on [[tofu]] or [[noodles]].
In [[Western cuisine]], ginger is traditionally restricted to sweet foods, such as ginger ale, [[gingerbread]], [[ginger snaps]], [[Parkin (cake)|ginger cake]] and [[ginger biscuits]].
Powdered dry ginger root (ginger powder) is typically used to add spiciness to [[gingerbread]] and other recipes. Ground and fresh ginger taste quite different and ground ginger is a particularly poor substitute for fresh ginger. Fresh ginger can be successfully substituted for ground ginger and should be done at a ratio of 6 parts fresh for 1 part ground. You generally achieve better results by substituting only half the ground ginger for fresh ginger.
In [[Myanmar]], ginger is used in a salad dish called ''gyin-tho'', which consists of shredded ginger preserved in oil, and a variety of nuts and seeds.
[[Indonesia]] has a famous beverage that called Wedang Jahe, which is made from ginger and palm sugar.
In traditional [[Cuisine of Korea|Korean]] [[Kimchi]], ginger is finely minced and added to the ingredients of the spicy paste just before the fermenting process.
In [[South East Asia]], the flower of a type of ginger is used in cooking. This unopened flower is known in the [[Malay language]] as [[Bunga Kantan]], and is used in salads and also as garnish for sour-savoury soups, like [[Laksa|Assam Laksa]].
Ginger has a [[sialagogue]] action, stimulating the production of [[saliva]].

The characteristic odor and flavor of ginger root is caused by a mixture of [[zingerone]], [[shoagole]]s and [[gingerol]]s, volatile oils that compose about one to three percent of the weight of fresh ginger.

Ginger produces clusters of white and pink flower buds that bloom into yellow flowers. Because of the aesthetic appeal and the adaptivity of the plant to warm climates, ginger is often used as landscaping around [[subtropical]] homes. It is a perennial reed-like plant with annual leafy stems, three to four feet high.
Historical methods of gathering the root describes, when the stalk withers, it is immediately scalded, or washed and scraped, in order to kill it and prevent sprouting. The former method, applied generally to the older and poorer roots, produces Black Ginger; the latter, gives White Ginger. The natural color of the "white" scraped ginger is a pale buff--it is often whitened by bleaching or liming, but generally at the expense of some of its real value.
== References in popular culture ==
*To members of [[the Race (Worldwar)|the Race]], an alien species in [[Harry Turtledove]]'s best-selling [[novel]] series [[Worldwar]], ginger is a highly addictive, [[psychoactive drug]], with an effect similar to that of [[cocaine]] or [[PCP]] in humans.
*In [[Cockney rhyming slang]], ''ginger'' is a derogatory euphemism for ''[[Homosexuality|homosexual]]''. The original slang rhymed ''[[queer]]'' with ''ginger beer''.
*In the west of [[Scotland]] (particularly [[Glasgow]]), ''ginger'' is a term for any carbonated [[soft drink]].
*Before the First World War, it was common for mounted regiments to receive large vats of root ginger before public ceremonies, which were peeled and cut into suppositories for the horses. The burning sensation made the horses hold their tails up; this practice is called [[Figging]] or feaguing.
*Ginger is also a common slang term in Great Britain for red-haired individuals. This term is also used in the [[South Park]] in episode [[Ginger Kids]]. In [[Harry Potter and the Deathly Hallows]], the drunk men yelling at Hermione used the term "Ginger" to describe Ron's red hair.
==Production trends==
[[Image:2005ginger.PNG|thumb|right|Ginger output in 2005]]
In 2005, China continued to lead the world in ginger production with a global share of almost 25% followed by India, Nepal and Indonesia.
== Similar species ==
[[Myoga]] (''Zingiber mioga'' Roscoe) appears in [[Japanese cuisine]]; the flower buds are the part eaten.
Another plant in the ''Zingiberaceae'' family, [[galangal]], is used for similar purposes as ginger in [[Thai cuisine]]. Galangal is also called Thai ginger. Also referred to as galangal, fingerroot (''[[Boesenbergia rotunda]]''), or Chinese ginger or the Thai ''krachai'', is used in cooking and medicine.
A [[dicotyledon]]ous native species of eastern
[[North America]], ''[[Asarum canadense]]'', is also known as "[[wild ginger]]", and its root has similar aromatic properties, but it is not related to true ginger and should not be used as a substitute because it contains the [[carcinogen]] [[aristolochic acid]]. This plant is also a powerful [[diuretic]], or urinary stimulator. It is part of the [[Aristolochiaceae]] family.

Historical methods of gathering the root describes, when the stalk withers, it is immediately scalded, or washed and scraped, in order to kill it and prevent sprouting.

The natural color of the "white" scraped ginger is a pale buff--it is often whitened by bleaching or liming, but generally at the expense of some of its real value.
