History
Urtica dioica, stinging nettle, is a rhizomatous perennial native across temperate Eurasia and widely naturalized in North America. Its defensive hairs, each a miniature hypodermic syringe, inject a cocktail of histamine, serotonin, acetylcholine, and formic acid into the skin. Despite the sting, humans have used the plant for millennia: Bronze Age burials in Denmark contained cloth woven from nettle fiber, medieval Europeans ate the young shoots as a purifying spring tonic, and twentieth-century shortages revived nettle-fiber textiles during both World Wars.
The leaves are rich in iron, vitamins, and minerals, and modern herbalism uses them for allergic rhinitis and urinary complaints. The cooked plant is entirely safe; only fresh contact stings.
Native to Europe, Asia, and North Africa, and likely also indigenous to parts of North America, Stinging Nettle has been used for at least 3,000 years as food, medicine, and textile fiber. In the US it is simultaneously a dreaded backyard weed and a beloved forager's spring green, now enjoying renewed popularity in artisan food and herbal medicine.
