Also known as Toxicodendron radicans, it is a plant that’s often found in North America. According to the U.S. Food & Drug Administration, this plant is found throughout the United States except the parts of the West Coast, Alaska, and Hawaii. People in contact with it would have an itchy rash and allergic reaction. Belonging to the cashew family, poison ivy can grow as a shrub or a vine and is found in various habitats such as fields, along roadsides, and forests. With smooth or toothed edges, each leaf has three glossy leaflets. 

Urushiol is an oily resin that serves as the leading cause of allergic reaction. This oily resin is often present in poison ivy’s roots, leaves, and stems. Urushiol can stick to the skin when you come into contact with the plant, even any object that touches the plant, resulting in a rash. Even urushiol in a small amount can trigger a reaction in sensitive individuals. Usually the symptoms of poison ivy rash appear within 12 to 48 hours after exposure. These symptoms can include swelling, redness, development of small blisters, and itching. A warning you need to remember from now on: Don’t scratch the blisters!
