What does cowhage mean?
Cowhage is the common name for Mucuna pruriens, a vigorous tropical climbing vine in the bean family, best known for the intensely itching hairs that clothe its seed pods. The name itself alludes to this effect: livestock brushing against the plant are tormented by the irritant, giving rise to the older synonym 'cow-itch.' Despite its fierce defenses, cowhage has long been valued in traditional medicine, particularly in Ayurveda, and modern pharmacology prizes it as one of the richest natural sources of L-dopa, the compound used to treat Parkinson's disease. In contemporary usage the word appears chiefly in botanical, medical, and supplement-industry contexts — in phrases such as 'cowhage extract' or 'cowhage powder' — rather than in casual conversation. For readers, cowhage is a striking example of a plant that is both a hazard and a resource: its velvety pods promise softness but deliver one of nature's most persistent itches, while its seeds supply a compound of genuine therapeutic importance.
nounA tropical climbing legume (Mucuna pruriens) whose pod hairs cause intense itching on contact; it is cultivated as a source of L-dopa and used in herbal medicine.
- The tropical climbing plant Mucuna pruriens, whose bristly pods cause severe skin irritation.
"The farm workers harvested cowhage with gloved hands, wary of the irritating hairs that cover its pods."
"Botanists studying Mucuna pruriens noted that even a light brush against cowhage left collectors scratching for hours."
"Supplements derived from cowhage are marketed as natural sources of L-dopa."
Rarely used; cowhage is almost always treated as uncountable, whether denoting the plant generally or the medicinal substance.
"The greenhouse collection included several cowhages from different tropical regions."
Touch a cowhage pod and you'll regret it: its velvet-looking hairs are loaded with mucunain, an enzyme that triggers one of nature's fiercest itches.

Etymology of cowhage
Cowhage arose as an alteration of the older English term 'cow-itch,' which directly described the plant's effect on grazing cattle. The word entered English around the seventeenth century, as European botanists and traders encountered the plant in the tropics. The scientific name Mucuna pruriens reflects the same character: Latin pruriens means 'itching.' Related vernacular names include velvet bean, reflecting the downy texture of the pods.
