Nettle
Urtica dioica
Also known as: stinging nettle, Urtica dioica, common nettle
A herbaceous perennial native across temperate Eurasia and naturalized in North America, defended by hollow silica-tipped stinging hairs that inject formic acid, histamine, and serotonin on contact. Despite (or because of) the sting, one of the most multi-use plants in European, Asian, and North American foodways and folk medicine: cooked or dried as a high-protein leafy green, brewed as tea and beer, used as a long bast fiber for cloth and rope long before flax dominated, and harvested as a mineral-rich animal feed and fermented biofertilizer.
Scientific
Urtica dioica is in family Urticaceae. Herbaceous perennial 1–2 m tall with opposite serrated leaves and inconspicuous green flowers in drooping clusters. The species name dioica — “two houses” — refers to its predominantly dioecious habit (male and female flowers usually on separate plants), though some populations are monoecious. The stinging defense comes from specialized trichomes on stems and leaves: hollow silica-tipped hairs that break off on contact, injecting a cocktail of formic acid, histamine, serotonin, acetylcholine, and leukotrienes. Cooking, drying, soaking, or thoroughly crushing the leaves destroys the trichomes and neutralizes the sting completely; the cooked plant is entirely safe and exceptionally nutritious — high in protein (up to 30% dry weight), iron, calcium, and vitamins A and K.
Long bast fibers in the stem are extracted by retting much like flax, producing a fine durable cloth. Bronze and Iron Age European burials have yielded nettle textile fragments predating widespread flax cultivation.
Cultural
Nettle has been a Eurasian wild food for as long as there has been Eurasian foraging — spring nettle soup is a tradition from Ireland to the Caucasus, with regional names: nokedli in Hungary, nässelsoppa in Sweden, crupnik in Belarus, jajko z pokrzyw in Poland. Kkachidari nettle dishes appear in Korean foraging tradition. Across the Himalayas, nettle (sisnu, allo) is both a cooked green and a fiber crop — allo cloth from Nepal’s Himalayan Girardinia diversifolia nettles is a major handicraft. Nettle beer is an old English country brew. In folk medicine across the species’ range, nettle is used for joint pain (the urtication practice of deliberately stinging an arthritic limb persists in several traditions), for postpartum blood-building, and as a spring tonic.
In organic gardening, purin d’ortie (fermented nettle slurry) is a widely used liquid fertilizer and foliar feed; the plant accumulates nitrogen and minerals from deep soil and releases them as the fermented liquid is applied around other crops.
Global presence
Wild abundance across temperate Eurasia, naturalized throughout North America (where the closely related Urtica gracilis is also native), New Zealand, Australia, and parts of South America. Limited commercial cultivation for tea and supplements in Europe; Nepali allo fiber production is the largest dedicated commercial nettle harvest. Otherwise the plant is overwhelmingly wild-harvested — a true commons crop.
