Poison Ivy

Poison Ivy, Oak and Sumac are a family of plant found all over North America, most commonly in wooded areas. These plants all produce urushiol, a sap or resin that causes an allergic reaction or contact dermatitis when it comes in contact with skin. This results in severe itching and an often painful rash. Some individuals are more sensitive than others.
