Forms, Preparation and Usage

Pulmonaria officinalis has been traditionally used for its medicinal properties, with various forms available including fresh leaves, dried tincture, powder, essential oil, and capsule.

It can be prepared as a tea by steeping dried leaves in hot water, or as a decoction by boiling the plant material for a longer period. Topical applications include making an infusion for poultices or salves to treat skin conditions. The recommended dosage for adults is typically 1-2 cups of tea per day, while children should only use it under medical supervision, with a lower dose.

Due to its potency, it is advised to use pulmonaria officinalis sparingly, with a duration of no more than two weeks unless otherwise directed by a healthcare professional.

Safety, Side Effects and Contraindications

Pulmonaria officinalis can be considered relatively safe when used in recommended doses for short periods, but it is important to note that it may cause mild gastrointestinal side effects such as nausea, vomiting, or diarrhea in some individuals.

There is limited research on its interactions with other medications or herbs, but it is advisable to consult a healthcare provider before combining it with anticoagulants, anti-inflammatory drugs, or other herbal supplements to avoid potential interactions. Special populations, including pregnant and breastfeeding women, should avoid pulmonaria officinalis due to insufficient evidence on its safety during these periods, and individuals with chronic illnesses should use it with caution under medical supervision.

To ensure safe use, always follow recommended dosages, start with small amounts to test for tolerance, and discontinue use if adverse effects occur.

Growing, Harvesting and Storage

Pulmonaria officinalis grows best in moist, well-drained soil that is rich in organic matter, preferring partial to full shade in temperate climates.

It thrives in cool, humid environments and requires consistent moisture, though it should not be overwatered to avoid root rot. Regular weeding and mulching help maintain soil moisture and suppress weeds, while dividing the plant every few years ensures continued vigor and growth. Harvesting is best done in early spring before the plant blooms, using a sharp knife to cut the leaves and stems carefully to preserve the plant for future growth.

To preserve its potency, the harvested parts should be dried in a cool, dark place with good airflow, then stored in airtight containers away from light and moisture.
