Poison ivy, poison oak, and poison sumac plants contain a compound called urushiol, which is a light, colorless oil that is found in the fruit, leaves, stem, roots, and sap of the plant. When urushiol is exposed to air, it turns brown and then black; plant leaves develop small black spots.
There are several ways that you can be exposed to urushiol:
By touching the sap or rubbing against the leaves of the toxic plant at any time of year
By touching something that has urushiol on it, such as animal fur or garden tools
By breathing in smoke when toxic plants are burned
Ginkgo fruit and the skin of mangoes also contain urushiol and can produce symptoms similar to poison ivy dermatitis
Poison ivy dermatitis is not contagious and cannot be passed from person to person. However, urushiol can be carried under fingernails and on clothes. If another person comes in contact with the urushiol, he or she can develop poison ivy dermatitis. I’ve seen multiple cases where the spouse picked up the laundry and that contact caused the poison ivy dermatitis.
Poison Ivy Signs and Symptoms
After contact with urushiol, approximately 50 percent of people develop signs and symptoms of poison ivy dermatitis. The symptoms and severity differ from person to person. These symptoms usually develop within four hours to four days after exposure to the urushiol. The symptoms are worse within 1 to 14 days after touching the plant, but they can develop up to 21 days later if one has never been exposed to urushiol before.
The most common signs and symptoms of poison ivy dermatitis:
Intense itching
Skin swelling
Skin redness
After the initial symptoms, allergic individuals develop fluid-filled blisters in a line or streak-like pattern. The blisters can occur at different times in different people; blisters can develop on the arms several days after blisters on the hands developed. This does not mean that the reaction is spreading from one area of the body to the other. The fluid that leaks from blisters does not spread the rash.
Poison ivy is usually diagnosed based upon how the skin looks. Further testing is not usually necessary.
