Was ist Stinging Nettle?
Nettle needs no introduction to anyone who's brushed one: hollow hairs inject formic acid and histamine on contact. Cooking, drying or crushing disarms them completely, revealing one of Europe's best wild foods — spinach-like, and denser in iron, calcium and protein than most cultivated greens. Armies have been clothed in nettle fibre and fed on nettle soup.
Medicinally the leaf is used for hay fever and as a mineral-rich tonic tea; the root, separately, has decent trial evidence for easing urinary symptoms of benign prostate enlargement (BPH). Leaf extracts also reduced arthritis pain in small studies — fittingly, since deliberately stinging arthritic joints (urtication) is one of Europe's oldest counter-irritant treatments.
Wirkung & Anwendungsgebiete
Prostate symptom relief (root)
The best-evidenced use: nettle root extract, alone or with saw palmetto, improved urinary flow and BPH symptom scores in several randomised trials. See a doctor first to confirm the diagnosis.
Hay fever folk standby (leaf)
Freeze-dried nettle leaf capsules eased allergy symptoms in a small trial; paradoxical (the sting contains histamine) but persistent in practice. Cheap and low-risk to try.
Joint comfort
Nettle leaf extract reduced pain and NSAID requirements in small osteoarthritis studies; topical urtication is ancient counter-irritation that some swear by.
Mineral-rich tonic
Cooked nettle or long-steeped nettle infusion delivers iron, calcium, magnesium and vitamin K in genuinely useful amounts — traditional postpartum and convalescence food.
Hair and skin rinse
Nettle tea as a final hair rinse is a European classic for oily scalp and shine.
So wendest du sie an
As food
Pick young tops (gloves!) in spring, before flowering. Two minutes of boiling or steaming kills the sting entirely: soup, pesto, anywhere spinach goes. Do not eat old, flowering nettles (gritty cystoliths).
Infusion
2 tsp dried leaf per cup, covered 10–15 minutes (herbalists often steep an ounce in a litre overnight for the mineral extraction); 1–3 cups daily.
Leaf capsules for allergies
Freeze-dried leaf, ~300 mg 2–3× daily at the start of symptoms, as in the trial.
Root extract for BPH
250–600 mg daily standardised root extract — after a medical diagnosis, not instead of one.
⚠️ Vorsichtshinweise
- BPH symptoms overlap with prostate cancer symptoms — get diagnosed before self-treating with root.
- Nettle's vitamin K can interfere with warfarin dose stability; the diuretic effect can add to diuretics and lithium.
- May lower blood sugar and blood pressure modestly — relevant if medicated for either.
- Avoid medicinal doses in pregnancy (traditional emmenagogue caution); food amounts are fine.
- The sting itself is harmless for most, but significant local reactions happen — dock leaf lore optional, antihistamines effective.

Häufige Fragen
Why doesn't cooked nettle sting?
Heat, drying and blending collapse the brittle hair structure and destroy the irritants. Even 30 seconds of wilting disarms them.
Leaf or root — which do I want?
They're nearly different herbs: leaf for food, allergies, minerals, joints; root specifically for prostate/urinary symptoms.
When is nettle season?
Spring for eating (young tops), again after cutting regrows fresh shoots. Once plants flower, leave them to the butterflies — five species depend on them.
