The plant has been used in a sweat bath to treat rheumatic-like pains all over the body. An infusion has been taken by a woman to relax the muscles when she is about to give birth. An infusion has also been used as a body rub to treat soreness and stiffness. The fresh leaves of nettles have been rubbed or beaten onto the skin in the treatment of rheumatism etc. This practice, called urtification, causes intense irritation to the skin as it is stung by the nettles. It is believed that this treatment works in two ways. Firstly, it acts as a counter-irritant, bringing more blood to the area to help remove the toxins that cause rheumatism. Secondly, the formic acid from the nettles is believed to have a beneficial effect upon the rheumatic joints. A decoction of the peeled bark has been used in the treatment of headaches and nose bleeds. An infusion of the roots has been used in the treatment of intermittent fevers.
Description of the plant:
Habitat of the herb:Moist places near the coast in California.
Edible parts of Stinging Nettle:Young leaves - cooked. A very nutritious food, high in vitamins and minerals, it makes an excellent spinach substitute and can also be added to soups and stews. Only use the young leaves and wear stout gloves when harvesting them to prevent getting stung. Although the fresh leaves have stinging hairs, thoroughly drying or cooking them destroys these hairs. Nettle beer is brewed from the young shoots.
Other uses of the herb:A strong flax-like fibre is obtained from the stems. Used for making string and cloth, it also makes a good quality paper. It is harvested as the plant begins to die down in early autumn and is retted before the fibres are extracted. A hair wash is made from the infused leaves, or a decoction of the roots. This is used as a tonic and antidandruff treatment. The following uses have been listed for U. dioica, but they are almost certainly also applicable to this species. The plant matter left over after the fibres have been extracted are a good source of biomass and have been used in the manufacture of sugar, starch, protein and ethyl alcohol. An oil obtained from the seeds is used as an illuminant. An essential ingredient of "QR" herbal compost activator. This is a dried and powdered mixture of several herbs that can be added to a compost heap in order to speed up bacterial activity and thus shorten the time needed to make the compost. The leaves are also an excellent addition to the compost heap and they can be soaked for 7 - 21 days in water to make a very nutritious liquid feed for plants. This liquid feed is both insect repellent and a good foliar feed. The growing plant increases the essential oil content of other nearby plants, thus making them more resistant to insect pests. Although many different species of insects feed on nettles, flies are repelled by the plant so a bunch of freshly cut stems has been used as a repellent in food cupboards. The juice of the plant, or a decoction formed by boiling the herb in a strong solution of salt, will curdle milks and thus acts as a rennet substitute. This same juice, if rubbed into small seams of leaky wooden tubs, will coagulate and make the tub watertight again. A beautiful and permanent green dye is obtained from a decoction of the leaves and stems. A yellow dye is obtained from the root when boiled with alum.
Propagation of Stinging Nettle:Seed - sow spring in a cold frame, only just covering the seed. Prick out the seedlings into individual pots when they are large enough to handle, and plant them out in the summer. Division succeeds at almost any time in the growing season. Very easy, plant them straight out into their permanent positions.
Cultivation of the herb:Moist places near the coast in California.
Known hazards of Urtica lyallii:The leaves of the plants have stinging hairs, causing irritation to the skin. This action is neutralized by heat so the cooked leaves are perfectly safe and nutritious. However, only young leaves should be used because older leaves develop gritty particles called cystoliths which act as an irritant to the kidneys.
