Species of flowering plant in the cashew family

Toxicodendron vernix, commonly known as poison sumac, is a species of flowering plant in the family Anacardiaceae. It is native to eastern North America and is known for its ability to cause skin irritation upon contact.

Description

Toxicodendron vernix is a deciduous shrub or small tree that can grow up to 9 meters (30 feet) tall. The leaves are pinnately compound, with 7 to 13 leaflets that are smooth-edged and pointed. The plant produces small, greenish flowers in clusters, which develop into white or grayish berries.

Habitat

Poison sumac typically grows in wet, swampy areas such as bogs and marshes. It is often found in the eastern United States, from Maine to Florida, and west to Texas and Minnesota. The plant prefers acidic, poorly drained soils.

Toxicity

The plant contains an oil called urushiol, which can cause an allergic skin reaction known as contact dermatitis. This reaction results in itching, redness, and blistering of the skin. Urushiol is present in all parts of the plant, including the leaves, stems, and berries.

Identification

Poison sumac can be distinguished from other sumacs by its smooth-edged leaflets and the presence of white berries. Unlike other sumacs, which have red berries and serrated leaflets, poison sumac's berries are white and its leaflets are smooth.

Prevention and Treatment

To prevent exposure to urushiol, it is important to recognize and avoid contact with poison sumac. If contact occurs, washing the affected area with soap and water as soon as possible can help reduce the severity of the reaction. Over-the-counter treatments such as calamine lotion and hydrocortisone cream can alleviate symptoms.
