Mucuna pruriens
Also known as Cowhage, Cowitch, Kapikachchu, Cowage (Seta siliquae hirsutae), kapikacchu, itching bean, Bengal bean, cì máo lí dòu, Kapikacchu, Atmagupta.
Mucuna pruriens is a vigorous annual climbing legume of the Fabaceae with purple flowers and pods covered in orange hairs that cause intense itching on contact. It grows wild in scrub and forest margins across the plains and lower hills of India and is cultivated as a fodder and green manure crop; the seeds are the medicine. Ayurveda knows it as Kapikacchu or Atmagupta, the foremost vajikarana seed, a heavy, sweet, warming tonic for the reproductive and nervous systems, and its seeds are now valued worldwide as the richest natural source of L-dopa.

Overview. Mucuna pruriens is a vigorous annual climbing legume of the Fabaceae with purple flowers and pods covered in orange hairs that cause intense itching on contact. It grows wild in scrub and forest margins across the plains and lower hills of India and is cultivated as a fodder and green manure crop; the seeds are the medicine. Ayurveda knows it as Kapikacchu or Atmagupta, the foremost vajikarana seed, a heavy, sweet, warming tonic for the reproductive and nervous systems, and its seeds are now valued worldwide as the richest natural source of L-dopa.
Clinical Notes. Seeds require processing (boiling/roasting) to reduce anti-nutritional factors and toxicity Natural L-DOPA may provide neuroprotection with fewer side effects than synthetic Ayurvedic Rasayana (rejuvenative) Use under medical supervision due to L-DOPA content Pod hairs cause severe skin irritation
Clinical Notes. The Ayurvedic practitioner gives Kapikacchu to build shukra and steady vata: the man with low sperm count or sexual weakness, the thin patient with tremor and wasting, the elder whose strength is failing.
Properties and Uses. The hairs or bristles of cowhage pods are employed as a vermifuge, and seem to act against the several species of worms, except the tape-worm. They are given in substance, and seem to act by piercing the worm, as no fluid preparation of them is of any worth as a vermifuge.
