méregységet

Méregységet is a Hungarian term that translates to "poison ivy" in English. It refers to a genus of toxic plants in the family Anacardiaceae, most notably *Toxicodendron radicans*. These plants are native to North America and are known for causing an allergic reaction in most people upon contact with their sap. The reaction is characterized by an itchy, blistering rash.

The toxic compound responsible for the allergic reaction is called urushiol. This oily substance is present in all parts of the plant, including the leaves, stems, and roots. It can remain active on surfaces, such as clothing or tools, for extended periods.

Symptoms of exposure to méregységet typically appear 12 to 48 hours after contact and can include redness, itching, swelling, and blisters. The severity of the reaction can vary depending on individual sensitivity and the extent of exposure. While most cases are mild and resolve on their own, severe reactions can require medical attention.

Prevention is key when dealing with méregységet. Avoiding direct contact with the plant is the most effective method. Wearing protective clothing, such as long sleeves, long pants, and gloves, can help minimize exposure. If contact occurs, washing the affected skin thoroughly with soap and water as soon as possible can help reduce the severity of the rash. Special washes designed to remove urushiol are also available.
