poison ivy oil

Poison ivy oil, called urushiol, is a type of oily sap found on the plant's leaves, stems, and roots. When contact occurs, urushiol can bind to the skin, triggering an allergic reaction that causes itching, redness, and blisters. The oil is very potent and can remain active on surfaces like clothing, tools, or pet fur for long periods, posing continued risk of exposure. Preventative measures include wearing protective clothing and washing skin promptly after contact. Allergic reactions vary among individuals, with some experiencing more severe symptoms than others.
