\nWhen you touch a nettle plant, the stinging hairs (trichomes) inject irritating chemicals into the skin. One of the primary compounds responsible for the burning sensation and rash is methanoic acid, also known as formic acid (HCOOH). Other irritants present include histamine, acetylcholine, and serotonin, which contribute to the inflammatory response.
