Ginger is the dried rhizome of the tropical plant Zingiber officinale. It is used in cookery, because of its aromatic volatile oil, and as a confection, either in syrup or 'crystallized' with sugar. In medicine, it is usually employed as a carminative, usually in the form of the tincture. It is grown principally in the East Indies (its original home), the West Indies, and tropical Africa.
