It can be prepared as a tea by steeping dried leaves in hot water, or as a decoction by boiling the plant parts for a longer period. Topical applications include using the powder or essential oil directly on the skin for localized treatments. The recommended dosage for adults is typically 1-2 grams of dried herb per cup of tea, taken up to three times daily, while children should only use it under medical supervision.

Due to limited research, it is advisable to use prunella vulgaris cautiously, with a duration of use not exceeding two weeks unless guided by a healthcare professional.

Safety, Side Effects and Contraindications

Prunella vulgaris can be used as a medicinal plant for its potential anti-inflammatory, antiseptic, and diuretic properties, but it should be used with caution due to its possible side effects and interactions.

Common side effects may include gastrointestinal discomfort, such as nausea or diarrhea, and allergic reactions in sensitive individuals. It may interact with certain medications, including diuretics and blood pressure medications, potentially increasing the risk of electrolyte imbalances or hypotension. Pregnant and breastfeeding women should avoid prunella vulgaris due to insufficient safety data, and it is contraindicated in individuals with kidney disease or those undergoing surgery.

To ensure safe use, consult a healthcare provider before taking prunella vulgaris, start with a low dose, and discontinue use if adverse effects occur.

Growing, Harvesting and Storage

Prunella vulgaris grows in well-drained soil that is loamy or sandy, preferring full sun to partial shade and moderate moisture levels.

It thrives in temperate climates and is often found in grasslands, woodland edges, and disturbed soils. To ensure healthy growth, regular watering is necessary during dry periods, while avoiding waterlogging to prevent root rot. Prunella vulgaris requires minimal maintenance, with occasional weeding and light pruning to encourage bushier growth and improve air circulation. For harvesting, the best time is during late summer to early autumn when the flowers are fully open, using clean shears to cut the stems just above the leaf nodes to preserve the plant's vitality.

After harvesting, the plant material should be dried in a cool, shaded area with good airflow to retain its medicinal properties, then stored in airtight containers away from light and moisture to maintain potency over time.
