Cymbopogon citratus – All about the aromatic lemongrass

Cymbopogon citratus, commonly known as lemongrass, is a versatile tropical plant prized for centuries for its fresh lemon scent, culinary uses, and medicinal properties. This grass belongs to the Poaceae family and grows primarily in warm climates such as Southeast Asia, Africa, India, and South America. Today, lemongrass is used worldwide in cuisines, herbal teas, aromatherapy, and natural care products.

Origin and characteristics

Cymbopogon citratus is a vigorous, clump-forming grass that produces long, narrow leaves with a characteristic lemon scent. In ideal conditions, the plant can grow up to 1.5 meters tall. The sturdy stems are light green to yellowish-white and are the most aromatic part of the plant.

The fragrant oils in lemongrass include citral, a substance responsible for its fresh citrus scent and also used in perfumes, cleaning products, and insect repellents. Lemongrass thrives in sunny locations in well-drained soil and can be grown both in the ground and in pots.

Culinary applications

Lemongrass is an essential ingredient in many Asian cuisines, particularly Thai, Vietnamese, and Indonesian. It's often used in soups, curries, marinades, and stir-fries. The tough outer layers are typically removed, after which the soft inner portion is finely chopped or bruised and added to dishes.

The fresh, lemony flavor pairs well with ingredients like coconut milk, ginger, chili pepper, and coriander. Thanks to its versatility, lemongrass is also popular in modern fusion dishes and is increasingly used in desserts, cocktails, and herbal teas.

Health benefits and medicinal properties

Cymbopogon citratus is known for its numerous health benefits. In traditional medicine, lemongrass is used to:

• to support digestion

• to reduce inflammation

• to reduce stress and anxiety

• to relieve headaches

• to stimulate natural resistance

Lemongrass contains antioxidants and phytonutrients that contribute to a healthy immune system. Lemongrass tea is especially popular for its calming effect and refreshing flavor. Lemongrass essential oil is also used in aromatherapy, where it is known for its invigorating and purifying properties.

Use in aromatherapy and skin care

Cymbopogon citratus essential oil is a powerful natural fragrance. In aromatherapy, lemongrass oil is used to purify the air, boost energy, and improve concentration. Thanks to its antibacterial and antifungal properties, the oil is often used in cosmetics, soaps, deodorants, and natural cleaning products.

Lemongrass oil can be applied diluted to the skin to combat acne, repel insects, and refresh the skin. However, undiluted oil can be irritating and should therefore be used with caution.

Cultivation and care

Lemongrass is easy to grow, both indoors and outdoors. Important tips:

• Place the plant in full sun

• Use airy, well-drained potting soil

• Keep the soil moist, but avoid stagnant water

• In colder climates: overwinter indoors or protect the plant from frost

With sufficient warmth and light, Cymbopogon citratus grows quickly and can be harvested regularly by cutting off the outer stems.
