Nettle is a herbaceous plant that is often found growing in the wild. Its distinctive feature is the presence of stinging hairs on its leaves, which cause painful stings when touched.

Nettle leaves contain stinging hairs that inject methanoic acid upon contact with the skin, resulting in a burning pain sensation.

Bee stings leave behind formic acid, which causes pain and irritation. Applying baking soda, a mild base, to the affected area helps neutralize the acid, providing relief from discomfort.
