What is Poison Ivy, Poison Oak, and Poison Sumac?
Poison ivy, poison oak, and poison sumac are plants that are found throughout North America. They all cause the same type of skin rash. More than 50% of people are sensitive to the oil of these plants. The rash is extremely itchy and can have streaks or patches of redness and blisters on exposed body surfaces (such as the hands). The rash appears 1 or 2 days after your child has been exposed to the plant in a forest or field.
