Trichopus zeylanicus is a small herbaceous plant, which is one of only two species of its genus, Trichopus. Formerly it was placed in its own family, Trichopodaceae, but is now included in the family Dioscoreaceae. The leaves are about 20 centimetres (7.9 in) long and grow from a rhizome. The shape of the leaves can be highly variable even within one location, but the most common shape is cordate. The herb grows on sandy soil near rivers and streams in shady places in lowland and intermediate altitude forests. It flowers year long and the fruits are thought to be dispersed by water. The unusual flowers are purplish black.

Modern Indian scientists learned the medical properties of Trichopus zeylanicus in December 1987 while on a scientific expedition to the Agasthia Hills in the Western Ghats. They noticed that their guides, belonging to the Kaani tribe, were very energetic in sharp contrast to themselves.
