To prepare it, a tea can be made by steeping dried leaves in hot water, while a decoction involves boiling the dried plant material for a longer period.

The recommended dosage for adults is typically 200-400 mg of standardized extract in capsule form, taken two to three times daily, while children should only use it under medical supervision.

Safety, Side Effects and Contraindications

Albizia lebbeck can be used as a medicinal plant for its calming and anxiolytic properties, but it should be used with caution due to limited long-term safety data.

Potential side effects include drowsiness, gastrointestinal discomfort, and in rare cases, allergic reactions. It may interact with sedatives, antidepressants, and other central nervous system depressants, increasing the risk of drowsiness or respiratory depression. Special populations such as pregnant or breastfeeding women, as well as those with chronic illnesses, should avoid or use it under medical supervision due to insufficient evidence on safety.

To ensure safe use, consult a healthcare provider before starting albizia lebbeck, follow recommended dosages, and discontinue use if adverse effects occur.

Growing, Harvesting and Storage

Albizia lebbeck grows best in well-drained, loamy soil with a slightly acidic to neutral pH, thriving in full sun to partial shade and requiring consistent moisture without waterlogging.

It prefers warm climates and can tolerate drought once established, though regular watering during the growing season promotes vigorous growth and better pod development. For optimal care, regular pruning of dead or diseased branches and occasional fertilization with a balanced NPK fertilizer can enhance its health and yield. Harvesting is best done when the pods turn from green to yellowish-brown, typically 3 to 4 months after planting, using hand-picking or cutting with a sickle to avoid damaging the plant.

To preserve its potency, the harvested pods should be dried in a shaded, well-ventilated area, then stored in airtight containers in a cool, dry place or refrigerated to maintain their medicinal properties.
