Poison Ivy Dermatitis

Poison ivy dermatitis is an allergic skin reaction caused by contact with the oil urushiol, found in poison ivy, poison oak, and poison sumac plants. When the skin touches these plants, urushiol can trigger an immune response, leading to redness, itching, swelling, and blisters. Symptoms typically appear within 1 to 3 days and can last for weeks. Treatment includes cleaning the affected area, using topical corticosteroids, and taking antihistamines to relieve itching. Avoiding the plants and recognizing them can help prevent future reactions.
