To ensure safety, start with low doses, monitor for adverse reactions, and avoid prolonged use to minimize the risk of dependency or toxicity.

Growing, Harvesting and Storage

Ilex paraguayensis grows in tropical and subtropical regions, thriving in well-drained, fertile soil with a pH between 6.0 and 7.5, and requires full sun to partial shade for optimal growth.

It prefers moderate to high humidity and consistent moisture, though it should not be overwatered to avoid root rot. Regular pruning and fertilization with a balanced organic fertilizer during the growing season help maintain plant health and promote leaf production. The best time to harvest the leaves is during the dry season, typically from May to September, using clean, sharp scissors to cut the leaves from the tips of the shoots to preserve plant vigor.

After harvesting, the leaves should be dried in a shaded, well-ventilated area to retain their potency, then stored in airtight containers in a cool, dark place to maintain their medicinal properties for extended periods.
