Toxicodendron vernix, commonly known as poison sumac,[4] or swamp-sumach,[5] is a woody shrub or small tree growing to 9 metres (30 feet) tall.[6][7] It was previously known as Rhus vernix. This plant is also known as thunderwood, particularly where it occurs in the southern United States.
Like its toxic relatives poison ivy and poison oak, all parts of the plant contain a resin called urushiol, which causes skin and mucous membrane irritation to humans. When the plant is burned, inhalation of the smoke may cause the rash to appear on the lining of the lungs, causing extreme pain and possibly fatal respiratory difficulty.
