To ensure safe use, always consult a healthcare provider before taking adhatoda vasica, follow recommended dosages, and discontinue use if adverse effects occur.

Growing, Harvesting and Storage

Adhatoda vasica grows best in well-drained, loamy soil that is rich in organic matter, with a pH range of 6.

0 to 7. 5, and requires full sun to partial shade for optimal growth. It thrives in warm climates with moderate rainfall, requiring regular watering during the growing season while ensuring good drainage to prevent root rot. Regular weeding, mulching, and periodic pruning help maintain its health and promote dense foliage, while monitoring for pests like aphids and leaf miners is essential for effective care. The plant is typically harvested during the monsoon season, when the leaves are most potent, using hand-picking to collect mature leaves without damaging the plant.

After harvesting, the leaves should be shade-dried promptly to retain their medicinal properties, stored in airtight containers in a cool, dry place, or refrigerated to preserve potency and extend shelf life.
