Chinese and Ayurvedic herbalism
Zedoary
Curcuma zedoaria
Also known as white turmeric, wild turmeric, kachur, Karchura, Shati (shared with Hedychium in some texts), Dravida.
Curcuma zedoaria is a stout rhizomatous herb of the ginger family with large leaves marked by a purple midrib and pale yellow flowers in a cone of pink bracts. Native to India and Indonesia, it is cultivated and half wild in the wetter parts of eastern and southern India, Bengal, Assam, Kerala and Sri Lanka. The rhizome, camphoraceous and bitter, is the Karchura of Ayurveda, an aromatic digestive and expectorant for kapha, a topical for swellings and skin, and, as a washed starch, a convalescent food. It is a cousin of turmeric and is also used in Chinese medicine to move blood.
