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[K]. 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.
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.
