A woody vine that is mostly found in North America, poison ivy/oak/sumac produces urushiol, a skin irritant that causes an itching rash in most of the people. It affects only those who come in contact with it, either directly, by touching the plant or rubbing against the bushes, or indirectly, by touching any substance that has urushiol present in it. Poison ivy, however, is not infectious or contagious and, hence, cannot spread from one person to another. The most common symptom of poison ivy is itching on the skin surface.
