Dried Split Ginger Root

It is a herbaceous perennial which grows annual stems about a meter tall bearing narrow green leaves and yellow flowers. Ginger is in the family zingiberaceae, to which also belong turmeric (curcuma longa), cardamom (elettaria cardamomum), and galangal. Ginger originated in the tropical rainforest in southern asia. Although ginger no longer grows wild, it is thought to have originated on the indian subcontinent because the ginger plants grown in india show the largest amount of genetic variation. Ginger was exported to europe via india in the first century ad as a result of the lucrative spice trade and was used extensively by the romans.
The distantly related dicots in the genus asarum are commonly called wild ginger because of their similar taste.
