While it is widely consumed and has nutritional benefits, excessive consumption or improper preparation may lead to gastrointestinal upset, including nausea, vomiting, and diarrhea.

Pregnant and breastfeeding women should avoid high doses of Ipomoea batatas due to potential risks to fetal or infant development, and individuals with chronic illnesses should consult a healthcare provider before use.

To ensure safety, it is recommended to use Ipomoea batatas in moderation, prepare it properly, and consult with a healthcare professional before incorporating it into any medicinal regimen.

Growing, Harvesting and Storage

Ipomoea batatas grows best in warm, tropical climates with well-draining, loamy soil rich in organic matter, requiring full sun exposure for optimal growth.

It thrives with consistent moisture, needing regular watering without waterlogging, and benefits from mulching to retain soil moisture and suppress weeds. Throughout its growth cycle, regular pruning of lower leaves improves air circulation and reduces disease risk, while fertilization with a balanced NPK fertilizer during the growing season promotes robust development. Harvesting occurs 8-12 months after planting, when the tubers are mature and the leaves start to yellow, using a garden fork to carefully extract them without damaging the roots.

To preserve potency, the harvested tubers should be dried in a cool, well-ventilated area, then stored in airtight containers in a cool, dark place or refrigerated to extend shelf life and maintain medicinal properties.
