Poison Ivy
Poison Ivy is a rash caused by a plant that releases an oily resin called urushiol. Once in contact with the skin, it causes an allergic reaction that creates redness, itching and often raised, fluid-filled, blisters. The rash itself, is not contagious, but any remaining urushiol on the skin or clothing, can continue to create problems.
​
Typically, poison ivy rashes can be treated at home but occasionally may be severe enough to require medical intervention.
