The small nettle ( Urtica urens ), also called pus nettle , is a type of plant from the genus of nettles ( Urtica ). It is widespread in Eurasia and is a neophyte in some areas of the world .
description
The small nettle grows as an annual herbaceous plant and reaches heights of 10 to 60 centimeters. The simple, dark green leaf blade is usually less than 5 cm long and ovate-elliptical with a wedge-shaped to blunt blade base. The leaf margin is serrated. The end tooth is no longer than the posterior teeth.
The flowers of the small nettle are single- sexed ( monoecious ). The inflorescences are usually shorter than the petiole. The flowers are unisexual. A single-seeded nut fruit is formed.
The number of chromosomes is 2n = 24.
ecology
The small nettle is a summer annual plant . It burns more than the great nettle ( Urtica dioica ). In Central Europe it is an archaeophyte , but today it is abducted worldwide in temperate and warm temperate areas ( cultural companion ). There is wind pollination . She is a warmth germ .
Locations
The small nettle is found scattered in the weed corridors of rubble sites or in gardens, in vegetable crops, at dung sites, especially in villages. It prefers nutrient-rich, extremely nitrogen-rich soils.
According to Ellenberg , it is a half-light plant , a freshness indicator , a pronounced nitrogen indicator and a class character of the ruderal societies and related arable and garden weed societies (Chenopodietea). In Central Europe it often occurs in the Urtico-Malvetum from the Sisymbrion association. In the Allgäu Alps, it rises to an altitude of 1000 meters.
use
pharmacology
The healing indications are similar to those of the great nettle ( Urtica dioica ). The same parts of the plant are also used: the leaves, the roots and, in folk medicine, the fruits (nettle seeds), i.e. the whole plant.
It is used for hives-like diseases of the skin, gout , kidney diseases, diseases of the musculoskeletal system and allergies . In anthroposophy , it is usually used in combination with arnica for burns , insect bites and sunburn .
nutrition
The small nettle can be used in many ways in the kitchen. The young shoots (harvest: April / May) are cooked in vegetable dishes, in fresh vegetable juice, raw and finely chopped in herb butter, in salads, as a sandwich, spinach, in herb sauces, in batter and as a dry spice. The green seeds (harvest: June / July) can be used as a topping on bread or roasted and the ripe ones (September) as an additive to wine. The leaf meal can in turn be used as powder for snuff or as a dry spice.
Other use
The small nettle, like the large nettle, is suitable for producing chlorophyll and was therefore used for this purpose in the past. However, it is not suitable for fiber production such. B. the Siberian hemp nettle , the reed nettle or the great nettle.
