To prepare lonicera japonica, it can be made into a tea by steeping dried leaves in hot water, or a decoction can be made by boiling the plant material for a longer period. It can also be used in an infusion or applied topically for skin conditions. 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.

Safety, Side Effects and Contraindications

Lonicera japonica can be used in traditional medicine for its purported health benefits, but it is important to be aware of its safety profile.

While generally considered safe when used in moderate amounts, it may cause gastrointestinal side effects such as nausea, vomiting, and diarrhea in some individuals. It is also associated with potential interactions with certain medications, including anticoagulants and antiplatelet drugs, which could increase the risk of bleeding. Due to limited research on its effects during pregnancy and breastfeeding, it is not recommended for use in these populations, and it should be avoided by individuals with chronic illnesses such as diabetes or hypertension.

To ensure safe use, it is advisable to consult a healthcare provider before taking lonicera japonica, start with low doses, and monitor for any adverse reactions.

Growing, Harvesting and Storage

Lonicera japonica grows best in well-drained soil that is rich in organic matter, preferring full sun to partial shade for optimal growth and flowering.

It thrives in temperate climates and requires regular watering, especially during dry periods, but should not be overwatered to avoid root rot. To ensure healthy growth, it benefits from annual pruning to remove dead or diseased branches and promote air circulation. The best time to harvest the flowers is in late spring to early summer when they are fully open, using gentle methods such as hand-picking to avoid damaging the plant.

After harvesting, the flowers should be dried in a cool, dark place with good ventilation to preserve their potency, and stored in airtight containers away from light and moisture to maintain their medicinal properties.
