More widely known by its popular name, poison ivy, it belongs to a distinguished family, the Anacardiaceae, which includes mangoes (Mangifera indica), pistachios (Pistacia verna) and the signature genus of the family, cashew nuts (Anacardium occidentale). Its own genus, Rhus, bears a name assigned by ancient Greek botanists, who knew a close relative as a culinary plant, the acid seed of which is still used in Syrian and Lebanese cooking as one of the ingredients – with olive oil, thyme and oregano – of Zaatar, a special fragrant bread. The genus is widely distributed throughout the temperate and sub-tropical regions of both hemispheres, and one or another member of it has been put to almost every economic use, providing, variously, cooked greens, spices, cooling beverages, tanning, dyestuffs, medicinal substances, varnishes and – in the oriental species R. verniciflua – fine Japanese lacquer.
