Toxicodendron radicans

Toxicodendron radicans, commonly known as poison ivy, is a plant found in North America that can cause skin irritation upon contact. It contains an oily resin called urushiol, which triggers allergic reactions in many people, leading to redness, itching, and blisters. The plant typically grows as a vine or shrub and is characterized by its leaves, which usually have three leaflets. It's important to recognize and avoid poison ivy when outdoors, as even touching the plant or objects it has touched can lead to a rash. Knowing how to identify it can help prevent uncomfortable reactions.
