Home > Health Library > Poison Ivy, Oak, and Sumac
Poison ivy, poison oak, and poison sumac are plants that have a sticky oil that can cause an itchy, red rash. The rash often shows up in lines or streaks along with blisters or large raised areas (hives). In some people, it causes serious symptoms such as swelling and widespread, large, oozing blisters.
Home treatment will often relieve mild symptoms. Prescription medicine may be needed for severe reactions.
