II- Legends and traditions

Nettle holds a great place in the popular traditions of the peoples of the Himalayas. Milarépa (1040-1123), the most revered saint by the Tibetans, owed his survival to him while he stayed in a cave for 12 years. Internally, he took the nature of the nettle (as he relates in his memoirs), externally, its skin and hairs turned green like a caterpillar, frightening passing hunters who at first took it for a ghost.


III- Botanical description

Description: Perennial herbaceous 60 to 150 cm high, forming colonies thanks to its long rhizomes. All of its organs are covered with two types of hairs: long stinging hairs and small flexible hairs. Its stems are erect and unbranched. The dark green, opposite leaves, oval to lanceolate, are usually twice as long as they are broad. They are lined with strong triangular teeth. The epidermal cells contain calcified corpuscles called cystoliths. The flowers are unisexual, tiny and united in clusters, male and female on different feet (dioecious form). The female clusters are drooping, the male clusters erect. The female flower is made up of 4 tepals, two of which are much larger enveloping a unilocular ovary and two outer ones. The male flower has 4 tepals and 4 stamens, curved into the bud and resiliently straightening at the anthesis, projecting a small cloud of pollen away. The pollination is anemophilous. The fruit is an ovoid achene, which remains enveloped in the two large accrescent tepals.


Nettle likes ruderalized wastelands, meadows, rubble and the surroundings of houses. It is a plant bioindicator of basic soils, rich in nitrogen, phosphorus and potassium. It signals an excess of organic matter or soil pollution by ferric oxides.

VII- The suggestion box 

Histamine and formic acid in the hairs are responsible for the stings associated with the plant. 

Nettle leaves are a good tonic for anemia. The plant's high vitamin C content helps ensure that iron is properly absorbed by the body. They remove uric acid from the body and therefore help relieve symptoms of gout and arthritis. Their astringent effect stops bleeding.
