Forms, Preparation and Usage

Prunus mume has been traditionally used in herbal medicine for its therapeutic properties, available in various forms including fresh fruit, dried fruit, tincture, powder, essential oil, and capsules.

To prepare it, the most common methods include making a tea by steeping dried fruit in hot water, creating a decoction by boiling the fruit or its powder, or using an infusion for a gentler extraction. For topical application, the essential oil can be diluted with a carrier oil and applied to the skin for conditions like inflammation or muscle pain. The recommended dosage for adults is typically 1-2 grams of dried fruit per day, while children should only use it under medical supervision due to its potency.

It is advised to use Prunus mume sparingly, with a duration of no more than two weeks unless directed by a healthcare professional.

Safety, Side Effects and Contraindications

Prunus mume can be used as a medicinal plant for its potential therapeutic effects, but its safety profile requires careful consideration.

While generally considered safe when used in moderate amounts, prunus mume may cause gastrointestinal side effects such as nausea, vomiting, and diarrhea in some individuals. It may also interact with certain medications, including anticoagulants and diabetes drugs, potentially increasing the risk of bleeding or hypoglycemia. Special populations, such as pregnant or breastfeeding women, should avoid prunus mume due to insufficient safety data, and individuals with chronic illnesses should consult a healthcare provider before use.

To ensure safe use, it is recommended to follow recommended dosages, consult with a healthcare professional, and discontinue use if adverse reactions occur.

Growing, Harvesting and Storage

Prunus mume grows in well-drained, slightly acidic to neutral soil that is rich in organic matter, with full sun to partial shade for optimal growth.

It requires consistent moisture, especially during the growing season, but should not be overwatered to avoid root rot. Regular pruning is essential to maintain shape, promote airflow, and encourage fruit production, while mulching helps retain soil moisture and suppress weeds. The fruit is best harvested in late spring to early summer when it turns from green to a deep red or yellow, using pruning shears to cut the fruit from the branch without damaging the plant.

After harvesting, the fruit should be dried in a shaded, well-ventilated area to preserve its medicinal properties, then stored in airtight containers in a cool, dark place to maintain potency over time.
