Stinging nettle

Urtica dioica

Also calledBrennnessel (German) · Ortiga (Spanish) · Ortie (French) · Bichhu bootī (Hindi, Himalayan nettles) · Anjura (Unani) · Yì zhū qiánmá 异株荨麻 (Chinese)

A plant armed with thousands of tiny glass-tipped syringes that inject an irritant cocktail into the skin. It is also nutritious, a source of fine linen-like fibre, and food for some of Europe's most familiar butterflies.

Urtica dioica, often known as common nettle, burn nettle, stinging nettle, nettle leaf, or just a nettle or stinger, is a herbaceous perennial flowering plant in the family Urticaceae. Originally native to Europe, much of temperate Asia and western North Africa, it is now found worldwide. Wikipedia

§1

What it can do

  1. iStinging hairs have silica tips that snap off and inject histamine, acetylcholine, serotonin and oxalic and tartaric acids
  2. iiGrows thickly wherever soil is rich in phosphate and nitrogen, marking old settlements for centuries
  3. iiiStem fibres are long and strong enough to spin and weave into cloth
  4. ivCaterpillar food for peacock, small tortoiseshell, red admiral and comma butterflies

Eatenyoung leaves and tops (cooked or dried) · seeds

Young tops are cooked as soup, pesto or tea; heat or drying destroys the sting. Use gloves when picking. Eat young growth before flowering; older leaves become gritty with cystoliths.

§3

In the medicine cabinet

TraditionUse
European folk medicineNettle tea as a spring tonic and diuretic; 'urtication', beating aching joints with fresh nettles, for rheumatism
UnaniAnjura seeds and leaves for cough, kidney stones and as a diuretic
Indigenous AmericanNative nettles were used by many nations, including Pacific Northwest peoples, for fibre, as food, and by urtication for arthritis
Modern phytotherapyRoot extracts for urinary symptoms of benign prostatic hyperplasia; leaf for arthritis and allergic rhinitis

Weight of evidence

Moderate. Some clinical trials with promising but limited or mixed results.

Active compounds

histamine, acetylcholine, serotonin, β-sitosterol, scopoletin, lignans, caffeoylmalic acid

CautionDiuretic effects may interact with lithium, blood-pressure and diabetes drugs. Mild digestive upset. Avoid medicinal doses in pregnancy. The sting can cause severe reactions in rare cases.

Marginalia

In Hans Christian Andersen's The Wild Swans (1838), the heroine weaves nettle shirts to break a spell on her brothers. During the First World War, Germany made uniform cloth from nettle fibre when cotton was blockaded.

Curiosity

A Bronze Age burial cloth from Lusehøj in Denmark, about 2,800 years old, turned out to be nettle fibre, and its chemistry suggests the nettles grew in Austria.
