Forms, Preparation and Usage

Urtica dioica has a variety of forms available, including fresh leaves, dried tincture, powder, essential oil, and capsules, each offering different methods of preparation and application.

It can be prepared as a tea by steeping dried leaves in hot water, or as a decoction by boiling the root or leaves for a longer period. For topical use, a poultice made from fresh leaves or a diluted tincture can be applied to the skin for conditions like inflammation or itching. The recommended dosage for adults is typically 1 to 3 grams of dried leaves per day, while children should only use it under medical supervision if deemed safe.

Due to its potency, it is advisable to use urtica dioica sparingly, with a duration of no more than 2 to 4 weeks, and to monitor for any adverse reactions.

Safety, Side Effects and Contraindications

Urtica dioica can be used as a medicinal plant for its potential anti-inflammatory, diuretic, and detoxifying properties, but it must be used with caution due to its potential to cause adverse effects.

Common side effects include gastrointestinal discomfort, such as nausea, vomiting, and diarrhea, as well as skin irritation or allergic reactions, especially in individuals sensitive to plants in the Urticaceae family. It may interact with medications such as diuretics, anticoagulants, and antidiabetics, potentially increasing the risk of side effects or reducing the effectiveness of these drugs. Pregnant and breastfeeding women should avoid urtica dioica due to insufficient safety data, and individuals with chronic conditions like kidney disease or hypertension should consult a healthcare provider before use.

To ensure safe use, it is recommended to start with small doses, monitor for adverse reactions, and consult a qualified healthcare professional before incorporating urtica dioica into a treatment regimen.

Growing, Harvesting and Storage

Urtica dioica grows in moist, well-drained soils in full sun to partial shade, preferring rich, loamy soil with a slightly acidic to neutral pH.

It thrives in temperate climates and can be planted in early spring after the last frost, with seeds or rhizomes planted about 2-3 cm deep. Regular watering is essential during the growing season, but the plant is somewhat drought-tolerant once established. To ensure optimal growth, mulching helps retain moisture and suppress weeds, while pruning excess foliage encourages stronger root development. Harvesting is best done in late summer to early autumn when the leaves are most potent, using gloves and a sharp knife to cut the stems just above the soil line, avoiding contact with the stinging hairs.

For storage, the harvested plant should be dried in a cool, dark place with good air circulation, then stored in airtight containers to preserve its medicinal potency and extend shelf life.
