Safety, Side Effects and Contraindications

Andrographis paniculata can be a beneficial medicinal plant used for its immune-boosting properties, but it is important to consider its safety profile. While generally well-tolerated, it may cause side effects such as gastrointestinal discomfort, nausea, and skin rashes in some individuals. It may interact with certain medications, including immunosuppressants and anticoagulants, potentially increasing the risk of adverse effects. Pregnant and breastfeeding women should avoid its use due to limited safety data, and individuals with chronic illnesses should consult a healthcare provider before use. To ensure safe use, it is advisable to follow recommended dosages, consult with a healthcare professional, and monitor for any adverse reactions.

Growing, Harvesting and Storage

Andrographis paniculata grows best in well-drained, loamy soil with a pH between 6.0 and 7.5, in full sun to partial shade, and requires regular watering to maintain consistent moisture without waterlogging. It thrives in warm climates with temperatures above 20°C, and should be planted in spring after the last frost. Regular weeding and pest monitoring are essential, along with occasional pruning to promote air circulation and prevent disease. Harvesting occurs when the leaves are fully developed, typically 6-8 months after planting, by cutting the stems just above the soil level to ensure regrowth. To preserve potency, the harvested plant is dried in a shaded, well-ventilated area, then stored in airtight containers away from light and moisture, ideally in a cool, dry place or refrigerated to maintain its medicinal properties.
