It is known to support the respiratory system by alleviating symptoms of asthma and bronchitis, while also promoting digestion by reducing nausea and improving gastrointestinal motility.

Its ability to reduce stress and anxiety also benefits the nervous system, setting it apart from other calming herbs such as valerian root.

Overall, cymbopogon citratus stands out as a versatile herb with broad therapeutic applications across multiple body systems.

Forms, Preparation and Usage

Cymbopogon citratus has been widely used for its therapeutic properties, available in various forms such as fresh leaves, dried tincture, powder, essential oil, and capsules.

It can be prepared as a tea by steeping dried leaves in hot water, or as a decoction by boiling the plant material for a longer period. Additionally, it can be used topically in the form of a diluted essential oil or as a powder mixed into topical applications. For adults, a typical dosage is 1-2 cups of tea daily, while children should only use it under medical supervision.

The duration of use should be conservative, typically not exceeding 2-4 weeks unless guided by a healthcare professional.

Safety, Side Effects and Contraindications

Cymbopogon citratus can be used as a medicinal plant for its potential therapeutic properties, but it is important to consider its safety profile.

While generally considered safe when used in moderate amounts, it may cause side effects such as gastrointestinal discomfort, allergic reactions, or skin irritation in some individuals. It may interact with certain medications, including sedatives, anticoagulants, and antidepressants, 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 discontinue use if any adverse reactions occur.

Growing, Harvesting and Storage

Cymbopogon citratus grows best in well-drained, loamy soil with a pH between 6.0 and 7.5, in a sunny location with at least 6 hours of direct sunlight daily.

It requires regular watering, especially during the growing season, but should not be overwatered to avoid root rot. To ensure healthy growth, it is important to fertilize the plants with a balanced NPK fertilizer every few months and to prune the lower leaves to encourage airflow and prevent disease. Harvesting is most effective during the early morning or late afternoon when essential oil content is highest, and the leaves should be cut just above the node to promote regrowth.

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