This is a kind of Tuber that grows on foot hills of Eastern Himalayas between the altitude of 500M to 1500M. Locally people call it Bhui Champa because its flower like Lily during monsoon. It is also called as Thunder Lily because during British period it was assumed that the lilies come out of the ground with the advent of thunder showers. The tubers remain underground throughout the year. When the lilies disappear and the leaves die out in autumn the tubers begin to synthesize starch into them. This starch contains medicinal properties and is used to treat bone fractures, muscular disorders and sprains. The starch found in this tuber is quiet sticky and its paste when applied and covered with a thin cloth on the affected part cures the problem within a week or more, depending upon the severeness of the problem.
