Poison ivy is a member of the Anacardiaceae (Cashew) family of plants that are mainly found in tropical regions; the poison ivy is commonly observed in North America in various forma and hence is difficult to identify. It contains the oil Urushiol which causes an allergic reaction in some people.

In most cases a poison ivy plant grows as a shrub and forms a knee high thicket. The leaves of the plant are compound; a leaflet is at the end of the stalk with two leaflets on its both sides.

Most people are able to identify poison ivy from their three leafed appearance; the leaves though are not the same in appearance in all cases though in most they are of medium size (about 8 cm) with serrated edges and of a dark green color which turns to red in fall. In open spaces and woodlands the poison ivy grows in the form of a tree that is commonly known as poison oak.

It can also grow in the form of vines on trees which have thin brown and hairy aerial roots. Poison ivy flowers are formed in small yellowish green clusters while the fruits are white and grape size and appear like miniature pumpkins.

Poison Ivy and poison oak contain urushiol which can cause allergic skin reactions. Rash begin after one or two days of exposure in the form itchy red bumps or blister and continue to spread for few days. It is not contagious. Cleaning with water and soap immediately after exposure reduces number of blisters. Oral antihistamine can work. Steroid creams can work but before appearance of blister. It is self treated after 3 weeks.  As urushiol is present in poison ivy, poison oak and poison Sumac, so rash due to all these three is of same type. For more details, visit Poison ivy, poison oak.
