Toxicodendron verrucosum

Toxicodendron verrucosum, also known as poison sumac, is a plant species native to the southeastern United States.

It contains urushiol, an oil that causes severe skin irritation and allergic reactions, making it highly toxic to humans.

Despite its toxicity, the plant has been used in traditional medicine for its medicinal properties, which include anti-inflammatory and antimicrobial effects.

The plant can be prepared as a tincture or infused oil to be used in herbal remedies, although caution and proper handling are essential due to its toxic nature.
