Kapikacchu is a tropical climbing legume known botanically as Mucuna pruriens, a member of the Fabaceae family native to tropical Asia and Africa. It bears long pods covered with highly irritating hairs, and the seeds are the parts most often used after careful processing.
In traditional Ayurvedic herbal practice, kapikacchu has been used in powdered and tonic preparations. It is a strongly characterized plant and is not handled casually because the fresh pod hairs can cause intense itching.
The common English name velvet bean refers to the seed-bearing pods, while cowhage refers to the irritating hairs that cover the pod surface.
