A plant genus of the family ANACARDIACEAE. This is the source of the familiar cashew nuts, which are heat treated to remove the irritant toxin. Cashew nut shell liquid (frequently abbreviated as CNSL) is a major source of alkenyl phenolic compounds, especially ANACARDIC ACIDS, cardol, and cardanol.
A plant genus of the family ANACARDIACEAE best known for the edible fruit.
A plant genus of the family Anacardiaceae, order Sapindales, subclass Rosidae. It is a source of gallotannin (TANNIC ACID) and of somewhat edible fruit. Do not confuse with TOXICODENDRON which used to be part of this genus.
A genus (formerly part of Rhus genus) of shrubs, vines, or trees that yields a highly allergenic oleoresin which causes a severe contact dermatitis (DERMATITIS, TOXICODENDRON). The most toxic species are Toxicodendron vernix (poison sumac), T. diversilobum (poison oak), and T. radicans (poison ivy). T. vernicifera yields a useful varnish from which certain enzymes (laccases) are obtained.
The outer layer of the woody parts of plants.
