To prepare hovenia dulcis, it can be brewed into a tea by steeping the dried fruit in hot water, or made into a decoction by simmering for a longer period. It can also be used as an infusion or applied topically for skin conditions. The recommended dosage for adults is typically 1-2 grams of dried fruit per day, while children should only use it under medical supervision if deemed safe.

Safety, Side Effects and Contraindications

Hovenia dulcis can be used as a medicinal plant for its potential hepatoprotective and antioxidant properties, but it should be used with caution due to its potential side effects and interactions.

While generally considered safe in moderate amounts, some individuals may experience gastrointestinal upset, such as nausea or diarrhea, and allergic reactions. It may interact with medications like anticoagulants, increasing the risk of bleeding, and should be avoided with alcohol due to its potential to enhance sedative effects. Special populations, including pregnant and breastfeeding women, should avoid hovenia dulcis 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 monitor for any adverse reactions.

Growing, Harvesting and Storage

Hovenia dulcis grows best in well-drained, loamy soil with a slightly acidic to neutral pH, thriving in full sun to partial shade and requiring regular watering during its growing season.

It is a hardy plant that tolerates a range of soil types but prefers consistent moisture without waterlogging. Regular pruning and weed control are essential for maintaining plant health and promoting vigorous growth, while mulching helps retain soil moisture and suppress weeds. The fruit is typically harvested in late summer to early autumn when the berries turn bright red and are fully mature, using hand-picking or gentle shaking to collect the berries without damaging the plant.

For optimal potency, the harvested fruits should be dried in a cool, shaded area, then stored in airtight containers in a cool, dry place or refrigerated to preserve their medicinal properties.
