The plant can be prepared as a tea by steeping dried fruits in hot water, or as a decoction by boiling the dried fruit for a longer period. It can also be made into an infusion or used 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.

Due to the potential for toxicity, usage should be conservative, with short durations and limited frequency to ensure safety.

Safety, Side Effects and Contraindications

Gardenia jasminoides can be used in traditional medicine for its purported effects on mood and digestion, but it must be approached with caution due to its potential toxicity.

Side effects may include gastrointestinal upset, dizziness, and in severe cases, liver damage or even death, particularly with high doses or prolonged use. It may interact with medications such as antidepressants, anticoagulants, and sedatives, increasing the risk of adverse effects. Pregnant and breastfeeding women should avoid gardenia jasminoides due to insufficient safety data, and individuals with chronic liver or kidney disease should use it with extreme caution.

To ensure safety, always consult a healthcare provider before use, start with low doses, and monitor for any adverse reactions.

Growing, Harvesting and Storage

Gardenia jasminoides grows best in well-draining, fertile soil that is rich in organic matter and slightly acidic to neutral in pH.

It thrives in full sun to partial shade, requiring at least 6 hours of direct sunlight daily for optimal growth and flower production. Regular watering is necessary, especially during the growing season, but the soil should not be waterlogged to prevent root rot. To ensure healthy growth, prune dead or diseased branches in early spring and apply a balanced fertilizer every few months. Harvesting occurs when the fruits turn a deep yellow or orange, typically in late summer to early fall, using a sharp knife to cut the fruit from the stem while avoiding damage to the plant.

For storage, the fruits should be dried in a cool, dark place to preserve their potency, then stored in airtight containers away from light and moisture, or refrigerated to extend shelf life.
