Common Name Standardized: stinging nettle Other: nettle Botanical Name Urtica dioica L. ssp. dioica Plant Family: Urticaceae Overview Introduction Nettle is a common botanical, native to Africa and western Asia. It has since become naturalized across the globe and can be found wild in many parts of the world. It grows in temperate climates, preferring shady regions with moist soil. Stinging hairs cover the live plant, helping to protect it from predation. When touched, the hairs cause stinging welts due to the content of formic acid. While the stings can be painful, they dont last long and rarely cause serious harm. After being picked, the acid deteriorates quickly and the stinging hairs begin losing potency within minutes. The harvested leaves are a favorite source of medicine and have also been used for centuries for food and fabric. The healing powers of nettle are well steeped in the folklore and traditions of various cultures. In one fairytale, The Wild Swans, the heroine is tasked with weaving shirts of nettle leaf in order to cure her eleven brothers who have been turned into swans by their evil stepmother.
