Description

Ginger is the rhizome of the plant Zingiber officinale, consumed as a delicacy, medicine, or spice. It lends its name to its genus and family (Zingiberaceae). It is sometimes called ginger root to distinguish it from other things that share the name ginger.Ginger (Zingiber officinale Roscoe) is a flowering plant, in the family Zingiberaceae whose rhizome, ginger root or simply ginger, is widely used as a spice or a folk medicine.It is a herbaceous perennial which grows annual stems about a meter tall bearing narrow green leaves and yellow flowers. Ginger is indigenous to south China, and was spread eventually to the Spice Islands, other parts of Asia and subsequently to West Africa. Other members of the family Zingiberaceae include turmeric, cardamom, and galangal. The distantly related dicots in the genus Asarum are commonly called wild ginger because of their similar taste.
