Cut sections feature creamy white, yellow, or red-colored crunchy flesh depending upon the variety. The root often contains thin strands of fibrils running lengthwise through its center, especially in overmature ones.

Galangal (Alpinia galanga), also known as "blue ginger," is a closely related herb that is used extensively in East Asian regions, especially in Thailand, Malaysia, and Indonesian cuisine. Galangal has mild, subtle flavor and less pungent than ginger.
