Safety, Side Effects and Contraindications

Centella asiatica can be a beneficial medicinal plant used for its potential effects on wound healing, cognitive function, and skin health, but it must be used with caution.

While generally considered safe when taken in recommended doses, it may cause side effects such as skin irritation, nausea, or headaches in some individuals. It may interact with certain medications, including anticoagulants and diuretics, potentially increasing the risk of adverse effects. Pregnant and breastfeeding women should avoid centella asiatica due to insufficient safety data, and individuals with chronic illnesses should consult a healthcare provider before use.

To ensure safe use, always follow dosage guidelines, start with a low dose, and consult a healthcare professional, especially if you are on other medications or have underlying health conditions.

Growing, Harvesting and Storage

Centella asiatica grows best in warm, humid climates with well-drained, loamy soil rich in organic matter, requiring full sun to partial shade for optimal growth.

It thrives in temperatures between 20°C and 30°C and needs regular watering to maintain moist but not waterlogged soil. For care and maintenance, regular weeding, mulching to retain moisture, and periodic fertilization with organic compost are essential to promote healthy growth and prevent pests. Harvesting is best done during the morning when the leaves are fresh, using sharp scissors to cut the top leaves without damaging the plant, allowing for regrowth.

To preserve potency, the harvested leaves should be shade-dried thoroughly, stored in airtight containers in a cool, dry place, or refrigerated in sealed bags to maintain their medicinal properties.
