Rhus tox is a homeopathic medicine prepared from Atlantic Poison Oak, Toxicodendron radicans (Anacardiaceae), also called Eastern Poison Ivy. It is a perennial shrub with climbing stems found mostly on the eastern side of North America. The plant contains urushiol, an irritating and oily sap, that reacts upon skin contact and creates blistering and itchy rashes in many cases.
Native Americans used Toxicodendron radicans in small doses for a variety of purposes, including to treat various skin conditions and to induce immunity to its leaves.
