1 Poison ivy, poison oak, and poison sumac are plants than can cause an itchy rash upon contact. 2  A substance called urushiol, found in these plants, causes the rash. 3  The rash is not contagious. 4  The rash usually disappears in one to three weeks.  The majority of cases can be treated at home.
Skin contact can cause redness, swelling, blisters, severe skin destruction, swelling of the eye (cornea), or loss of sight. To prevent poison ivy from causing skin irritation, wash exposed area with water within 5 to 10 minutes of contact. Use soap and water first, then ether or alcohol.
