Poison sumac rash, also known as Toxicodendron vernix dermatitis, is a skin condition caused by contact with the sap of the poison sumac plant. This plant belongs to the Anacardiaceae family and is usually found in humid areas of North America. The rash occurs when the skin comes into direct contact with the oily sap produced by the plant. The sap contains a powerful allergen called urushiol, responsible for triggering an allergic reaction in susceptible people.
Symptoms of a poison sumac rash usually appear between 12 and 72 hours after exposure. Initial signs may include severe itching, redness, and swelling of the affected area. As the reaction progresses, small blisters filled with clear liquid may appear, which may eventually burst and form scabs. The rash usually lasts 1 to 2 weeks and can be very uncomfortable for the affected person.
Important information:
- Poison sumac rash is caused by contact with the sap of the poison sumac plant.
- The rash begins with itching, redness and swelling, followed by blistering.

The leaflets are elliptical in shape and the tips are smooth and pointed.

It prefers to grow in moist soil and thrives in habitats with high humidity and standing water. This plant is found primarily in the eastern and southeastern regions of the United States, as well as parts of Canada.
Fun Fact: Poison sumac is often overlooked or confused with harmless plants due to its similar appearance to other species. It is essential to correctly identify the plant to avoid accidental contact and the subsequent allergic reaction.

The allergic reaction triggers an oily resin called Urushiol, which is present in the plant sap. This resin is a powerful irritating that can easily penetrate the skin and trigger an immune response. The resulting symptoms include redness, swelling, itching and formation of ampoules or eruptions in the area affected by the skin.

When exploring areas that can contain poisonous Zumaque, it is recommended to wear protective clothing, such as long sleeves, long pants, gloves and closed footwear. In addition, applying a barrier cream or lotion containing Bentoquatam can help provide a protective layer on the skin. In case of exposure, it is crucial to wash the affected area with soap and water as soon as possible to eliminate any trace of Urushiol.
