Poison oak assumes a variety of confusing disguises ranging from small shrub to snaky vine. Part of the subterfuge is leaf shape, which varies from plant to plant. The telltale sign of poison oak (or for what could be poison oak) is a cluster of three leaves. Many people develop an itchy, red rash after contact with poison oak. If you think you touched poison oak, or touched someone or something that touched poison oak (a dog, for example), wash immediately with soap and cool water. The urushiol oil from the plant can linger on clothes, gear, and pets’ fur until it is washed off. Many stores sell products that help suppress the symptoms.
