Why does Poison Ivy Cause a Rash ?

Urushiol

  • Poison Ivy rash is caused by an oily resin called urushiol, found in the leaves, stems and roots of poison ivy, poison oak and poison sumac.
  • Urushiol is very sticky, so it easily attaches to your skin, clothing, tools, equipment or pet’s fur. You can get a poison ivy reaction from direct touch, touching contaminated objects, and inhaling smoke from the burning plants.
  • A poison ivy rash itself is not contagious.
