Health Encyclopedia: Poison Ivy Oak Sumac

Definition

Poison ivy , oak, or sumac poisoning is an allergic reaction that results from touching the sap of these plants. The sap may be on the plant, in the ashes of burned plants, on an animal, or on other objects that came in contact with the plant, such as clothing, garden tools, and sports equipment.

Small amounts of sap can remain under a person's fingernails for several days unless it is deliberately removed with very good cleaning.
