Culinary Uses: Beyond Lemongrass Tea
While many people are familiar with lemongrass tea, the culinary applications of Cymbopogon extend far beyond that. In Southeast Asian cuisine, lemongrass stalks are a staple ingredient, adding a zesty flavor to dishes like Tom Yum soup and Vietnamese pho.

While more research is needed to fully understand the medicinal potential of Cymbopogon, the preliminary findings are promising.
Essential Oils: A Concentrated Dose of Cymbopogon Goodness
The essential oils extracted from various Cymbopogon species are highly valued for their therapeutic properties. Lemongrass essential oil is known for its uplifting and energizing aroma, while citronella oil is a powerful insect repellent. Palmarosa oil is prized for its calming and soothing effects.
These essential oils can be used in aromatherapy, massage therapy, and natural perfumery. They can also be added to lotions, soaps, and other personal care products.
