Rhus Toxicodendron, commonly known as poison ivy, is a plant native to North America. It is recognized for its three-leaf clusters, which can cause skin irritation upon contact due to an oil called urushiol. This oil triggers allergic reactions in many people, leading to rashes, itching, and blisters. The plant typically grows as a vine or shrub and can be found in various habitats, including forests, fields, and along roadsides. Rhus Toxicodendron is an important part of its ecosystem, providing food and shelter for wildlife, despite its potential to cause discomfort in humans.
