Mucuna pruriens
Also called Velvet Bean, Cow Itch, Cowage, Itchy Bean
Cowitch is a tropical climbing legume, often grown as a fodder, green manure and food crop, with vines reaching over 15 metres. Its young foliage and seed pods cause intense itching on contact, so handle with care.
Mucuna pruriens is a tropical legume native to Africa and tropical Asia and widely naturalized and cultivated. Its English common names include monkey tamarind, velvet bean, Bengal velvet bean, Florida velvet bean, Mauritius velvet bean, Yokohama velvet bean, cowage, cowitch, lacuna bean, and Lyon bean.
The plant is notorious for the extreme itchiness it produces on contact, particularly with the young foliage and the seed pods. It also produces many medium-sized red swollen bumps on the skin with the itching. It has agricultural and horticultural value, and is used in herbalism.
In many parts of the world, M. pruriens is used as an important forage, fallow and green manure crop. Since the plant is a legume, it fixes nitrogen and fertilizes soil. In Indonesia, particularly Java, the beans are eaten and widely known as 'Benguk'. The beans can also be fermented to form a food similar to tempeh and known as Benguk tempe or 'tempe Benguk'.
