Growing, Harvesting and Storage

Jateorhiza palmata grows in tropical and subtropical regions, thriving in well-drained, loamy soil with a pH between 6.

0 and 7. 5, and requiring full sun to partial shade for optimal growth. It prefers consistent moisture but should not be waterlogged, so regular watering is necessary during the growing season, while allowing the soil to dry slightly between waterings. To ensure healthy growth, regular weeding, pruning of dead leaves, and mulching around the base of the plant can help maintain its vigor and prevent pests. The best time to harvest the roots is during the dry season, typically between June and September, when the plant's active compounds are most concentrated, and the roots are fully developed.

After harvesting, the roots should be carefully cleaned, sliced, and dried in a shaded, well-ventilated area to preserve their potency, then stored in airtight containers in a cool, dark place or refrigerated to maintain their medicinal properties.
