About

Toxicodendron pubescens (syn. Rhus pubescens), commonly known as Atlantic poison oak or eastern poison oak, is an upright shrub which can cause contact dermatitis for most people.

Safety

All parts of this plant contain urushiol, which can cause severe dermatitis in sensitive individuals. The risk of exposure may be reduced by learning to recognize and avoid this species and wearing clothing that covers the legs and arms. Contaminated clothing should be laundered before subsequent handling or use.

Effects of poison oak are similar to those of its close relative poison ivy. It causes severe itching, inflammation, and blistering.

Where it grows

This species is native to the Southeastern United States from Virginia westward to Texas and Oklahoma.
