An oil found in plants of the family Anacardiaceae, causing an allergic skin rash on contact; consists of a variable mixture of several organic compounds.
Origin: From うるし
Urushiol is an oily organic allergen found in plants of the family Anacardiaceae, especially Toxicodendron spp.. In sensitive individuals, urushiol can cause an allergic skin rash on contact, known as urushiol-induced contact dermatitis. The name comes from the Japanese word for the tree Toxicodendron vernicifluum. The oxidation and polymerization of urushiol in the tree's sap in the presence of moisture allows it to form a hard lacquer, which is used to produce traditional Chinese, Korean and Japanese lacquerware.
