Poison Sumac

Poison sumac (Toxicodendron vernix or Rhus vernix) is a woody shrub or small tree growing to 9 m (30 ft) tall. All parts of the plant contain a resin called urushiol that causes skin and mucous membrane irritation to humans. When 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.

Famous quotes containing the word poison:

    There is such a thing as food and such a thing as poison. But the damage done by those who pass off poison as food is far less than that done by those who generation after generation convince people that food is poison.
    Paul Goodman (1911–1972)
