Definition
This section has been translated automatically.

Plant genus in the almost worldwide family of the stinging nettle plants (Urticaceae). Stinging nettles are mostly annual herbaceous plants that reach growth heights of 10 to 300 cm and can be found everywhere in Germany. The green parts of the plant are covered with stinging and bristle hairs. The serrated leaves are elliptical, lancet-shaped or heart-shaped.
The nettles are known and feared because of the painful wheals (swellings) that develop in the skin after touching the stinging hairs. These stinging hairs are a protective mechanism against predators. The active ingredients of the stinging liquid are serotonin, histamine, acetylcholine and sodium formate.
