Nettles cause irritation due to the presence of formic acid in their tiny hairs. When these hairs come into contact with the skin, they break open and release the formic acid, causing a stinging sensation and redness.

Formic acid is a naturally occurring compound found in plants and animals, including nettles. It is a strong acid that can cause irritation and discomfort when it comes into contact with the skin. Some people may experience a mild reaction, while others may have a more severe allergic response.

If you come into contact with nettles and experience irritation, it is important to wash the affected area with soap and water to remove any remaining formic acid. Applying a soothing cream or lotion can also help to alleviate the discomfort. In some cases, an antihistamine or corticosteroid cream may be necessary to reduce inflammation and itching.

It is important to note that while formic acid can cause irritation, it is not typically dangerous or harmful. However, if you experience a severe reaction or have difficulty breathing after coming into contact with nettles, seek medical attention immediately.
