Possibly native to Indo-China, but nowadays cultivated almost throughout tropical Asia, mainly as an ornamental but especially in South-East Asia also for medicinal purposes; regularly escaping from cultivation.
In Indonesia, rhizomes are used to treat abdominal illness; the watery little corms are considered cooling. In the Philippines, rhizomes are used internally to treat gastric complaints, and externally, mixed with oil, as a cicatrizant. They are also used in perfumery and as a means to preserve cloth from insects. Leaves and rhizomes are eaten fresh or cooked as a vegetable and used in cosmetic powder and as a food flavouring agent.
