Toxicodendron radicans, commonly known as eastern poison ivy[3] or poison ivy, is a species of allergenic flowering plant. It has numerous subtaxons and forms both vines and shrubs. Despite its common name, it is not a true ivy, but rather a member of the cashew and pistachio family Anacardiaceae. It is different from western poison ivy, Toxicodendron rydbergii, and resembles a number of species.
The species is found in North America. Although commonly eaten by animals, with birds consuming the seeds, T. radicans is considered a noxious weed. As a poison ivy, if causes urushiol-induced contact dermatitis in most people who touch it, producing an itchy, irritating, and sometimes painful rash.
