Nettle

The nettles (Latin Urtica ) are a kind of the family of the Urticacée S which gathers about thirty Espèce S of herbaceous plants with hairy sheets. One finds of them 7 in Europe including 4 in France.

The irritant hairs contain formic Acid , Histamine, Acétylcholine and Sérotonine which irritate the Peau with its contact. These hairs have at their end a point of Silice which makes it possible to penetrate the skin of the animals which approach too much it. The irritant hairs of the nettle are as fragile as glass. They break like the end of the bulbs of drugs and inject into the skin an irritating liquid.

The most common species are the great nettle ( Urtica dioica , 50 cm with 1 meter) and the Stinging nettle ( Urtica urens , less than 50 cm). Urtica will pilulifera (Ortie with pills, Roman Ortie) meets in midday and the west of France and Corsica Urtica atrovirens only in

General characteristics

In fact herbaceous plants, with Feuille S opposed, of elliptic form, toothed push on the rich grounds. All the plant is covered with irritant hairs. The male and female flowers are separate, either on same the foot (plants Monoïque S) or on different feet (plants Dioïque S). They are greenish flowers, joined together in Inflorescence S more or less tight according to the species: Panicle S, ears, Cluster S…

Moreover the nettle is a genuine hearth for “useful fauna”, in particular of many species of butterfly S and the Punaise S.

Components

  • the sheets are very rich in proteins (40% of the dry weight)
  • sheets and stems contain rock salt (Calcium, Potassium), Silice and vitamins has and C
  • It is the presence of histamine and acéthylcholine which gives to the nettle its irritant capacity.
  • In the roots which are not used there are Phytostérol S and Coumarine.

Uses

Food

The nettle is also cultivated at food ends.

The sheets are edible, young they can be eaten raw chopped out of salad but they are especially consumed cooked in Soupe, more rarely in Légume, in gratins, the quiches or in the Potée with the Nettles.

The sheets of nettles contain Protéine S foliar in good quantity (9g for 100g of sheets), as well as minerals like the Fer and the Zinc. The nettles contain seven times more Vitamine C that the orange S.

Medicinal properties

The nettle is diuretic, tonic and antianemic by its rock salt contribution. Apart from soups and Herb tea S, one makes scented drinks of them.

It is used for the treatment of the Scalp, the fatty hair and the pellicular .

In addition, the gardeners who want to stimulate to them Blood circulation on the level of the Jambe S can go to mow foot S naked the nettles. The punctures of nettles are traditionally regarded as being able to relieve the joint pains of rheumatisms and the pains sciatic nerves.

Textile

The fibers of nettle were used to manufacture cords and fabrics, especially in the north of Europe and are still used to manufacture the Papier on which are printed the banknotes (replacing those of the hemp).

Ötzi carried a knife whose sleeve was a weaving in nettle, and remained intact after having spent 5300 years in the ices. The Ramie is close to the nettle besides.

Gardening: liquid manure of nettle

The market-gardening gardeners and wanting to respect the principles of the Organic farming prepare with the nettles, by Fermentation, of the liquid manure of nettle which with the property to push back the Insecte S, in particular the Puceron S; it can also constitute a Engrais.

Rich person out of nitrogen, iron, potash and trace elements, the liquid manure of nettle constitutes a good strengthening for the plants and stimulates the growth and natural resistance against the enemies and the diseases. It is used in biological gardening to reinforce the immunity of the plants and to avoid the treatments and the pesticides.

Impact on the biodiversity

The use of liquid manure of nettle, like the preventive mowing of many surfaces, like the sides, can cause the destruction of many species of insects like the Petite tortoise, the Paon of the day, the Vulcan, the Vanesse of the thistle, etc, whose larvae live in the sheets or even hang their chrysalis on the seedling.

Legislation

In France: A decree of July 1st, 2006, pursuant to the law of agricultural orientation of January 2006, prohibited marketing, the detention and the promotion of not approved plant health products. This decree whose application causes many questions does not call into question the clothes industry and the domestic use of the liquid manure of nettle.

On Sunday, March 25, 2007 with 12:25, the radio " Info" France; announces that “it - mythical liquid manure of nettle is again authorized”

Punctures of nettles

One can relieve the punctures of nettles by rubbing Plantain there: it is a plant with round sheets and veins pronounced, which generally pushes close to urticacées.

Other plants called nettle

Other species of plants also received the vernacular Nom of “nettle” because of their vague resemblance to the nettles. One thus knows white dead-nettles, yellow, reds which belong to the kind Lamium (Lamier) of the family of the Lamiacées. These plants are distinguished from the true nettles to their stem with square section and their coloured flowers zygomorphes.
  • white dead-nettle = white Tinsel maker ( Lamium album )

  • yellow nettle = yellow Tinsel maker ( Lamium galeobdolon )
  • red dead-nettle = Tinsel maker crimson ( Lamium purpureum )
  • dead nettle = white Tinsel maker ( Lamium album ) or Tinsel maker mottled ( Lamium maculatum )
  • mackled nettle = Tinsel maker mottled ( Lamium maculatum )
  • nettle bourbière = épiaire of the marshes ( Stachys palustris )
  • nettle puante = épiaire of wood ( Stachys sylvatica )
