To ensure safe use, it is recommended to consult a qualified healthcare professional, start with a low dose, and monitor for any adverse reactions.

Growing, Harvesting and Storage

Hydrocotyle asiatica grows best in moist, well-drained soil with a pH range of 5.5 to 7.0, thriving in partial to full sun and requiring consistent moisture throughout the growing season.

It is typically planted in early spring after the last frost, and it benefits from regular watering to maintain soil humidity without becoming waterlogged. To ensure healthy growth, it is important to remove any dead leaves and control weeds around the plant, while also ensuring good air circulation to prevent fungal diseases. Harvesting should occur in the early morning when the leaves are dewy, using clean shears to cut the leaves just above the stem, ensuring minimal damage to the plant.

After harvesting, the leaves should be dried in a cool, shaded area with good airflow, then stored in airtight containers in a cool, dark place to preserve their medicinal potency and extend their shelf life.
