Safety, Side Effects and Contraindications

Cymbopogon citratus can be a beneficial medicinal plant, commonly used for its calming and digestive properties, but it should be used with caution due to potential side effects and interactions.

While generally safe in moderate doses, excessive consumption may lead to gastrointestinal discomfort, drowsiness, or allergic reactions in sensitive individuals. It may interact with medications such as anticoagulants, antidepressants, and sedatives, potentially increasing their effects or causing adverse reactions. Special populations, including pregnant and breastfeeding women, should avoid cymbopogon citratus due to insufficient safety data, and individuals with chronic illnesses should consult a healthcare provider before use.

To ensure safe use, it is recommended to follow recommended dosages, consult a healthcare professional, and discontinue use if any adverse effects occur.

Growing, Harvesting and Storage

Cymbopogon citratus grows best in warm, tropical climates with well-drained, loamy soil that is rich in organic matter and slightly acidic to neutral in pH.

It requires full sun exposure for optimal growth and should be watered regularly, but not overwatered, to avoid root rot. Regular pruning and weeding are essential for maintaining plant health, while fertilization with a balanced NPK fertilizer during the growing season promotes vigorous growth. Harvesting is most effective during the early morning or late afternoon, when essential oils are most concentrated, using sharp scissors to cut the upper portion of the plant just above the node.

To preserve potency, the harvested leaves should be dried in a cool, shaded area with good air circulation, then stored in airtight containers away from light and moisture, ideally in a cool, dark place or refrigerated to maintain freshness and efficacy.
