Curcuma

Curcuma is a genus of plants in the family Zingiberaceae that contains such species as turmeric and Siam tulip. They are native to Southeast Asia, southern China, the Indian Subcontinent, New Guinea and northern Australia.[3]

Some species are reportedly naturalized in other warm parts of the world such as tropical Africa, Central America, Florida, and various islands of the Pacific, Indian and Atlantic Oceans.

Generally, most curcuma grows well in loose and sandy soil in shaded areas.[2][4]

The name is derived from the Sanskrit kuṅkuma, referring to turmeric. Turmeric has been used in India for medical purposes since ancient times [5] and is frequently used to flavour or colour curry powders, mustards, butters, and cheeses; it may also be a substitute for saffron and other yellowish pigments.[6]
