The recommended dosage for adults is typically 1-2 teaspoons of dried herb per cup of hot water, taken up to three times daily, while children should only use it under professional guidance due to limited safety data.

Use should be conservative, with a duration of no more than two weeks unless advised by a healthcare provider.

Safety, Side Effects and Contraindications

Epilobium angustifolium can be used as a medicinal plant for its potential anti-inflammatory and wound-healing properties, but it should be used with caution.

While generally considered safe when taken in recommended doses, it may cause side effects such as gastrointestinal upset, nausea, and allergic reactions in some individuals. It may interact with anticoagulant medications, increasing the risk of bleeding, and should be avoided with herbs like ginkgo biloba or garlic. Pregnant and breastfeeding women should avoid epilobium angustifolium due to insufficient safety data, and individuals with chronic bleeding disorders or those undergoing surgery should consult a healthcare provider before use.

To ensure safe use, always consult a qualified healthcare professional, start with low doses, and monitor for any adverse reactions.

Growing, Harvesting and Storage

Epilobium angustifolium grows in moist, well-drained soils in full sun to partial shade, typically in meadows, stream banks, and woodland edges.

It thrives in cool, temperate climates and requires consistent moisture without waterlogging, making it suitable for regions with moderate rainfall or irrigation. To ensure healthy growth, regular weeding and occasional fertilization with organic compost can promote vigorous foliage and flowering. Harvesting is best done in early summer when the leaves are young and tender, using clean shears to cut the stems just above a node to encourage regrowth.

For optimal potency, the harvested plant should be dried in a shaded, well-ventilated area, then stored in airtight containers away from light and moisture, preferably in a cool, dark place or refrigerated to maintain its medicinal properties.
