Herb: Scrub Nettle
Latin name: Urtica incisa
Family: Urticaceae (Nettle Family)
Edible parts of Scrub Nettle:Young leaves - cooked. A tasty vegetable. 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.
Description of the plant:
Habitat of the herb:Usually in damp gullies in Australia. Lowland to montane forests, forest margins and shaded open places throughout New Zealand.
Other uses of Scrub Nettle: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. 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 hair wash is made from the infused leaves and this is used as a tonic and antidandruff treatment. 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 the herb: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 Scrub Nettle:Usually in damp gullies in Australia. Lowland to montane forests, forest margins and shaded open places throughout New Zealand.
Medicinal use of the herb:None known
Known hazards of Urtica incisa: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.
