Rating (out of 5): 3

Lemongrass (Cymbopogon citratus) has a history of traditional use for various ailments, including infections, but its application in supporting or treating fungal infections is also supported by a growing body of scientific evidence. The essential oil extracted from lemongrass contains high levels of citral and other terpenoids, compounds known for their antimicrobial properties. Several in vitro studies have demonstrated that lemongrass essential oil exhibits significant antifungal activity against a variety of fungal species, including Candida albicans, Aspergillus spp., and Trichophyton spp., which are common pathogens in human fungal infections (source). The proposed mechanisms include disruption of fungal cell membrane integrity and inhibition of spore germination.

While laboratory findings are promising, clinical evidence in humans is still limited. A few small-scale studies and case reports suggest potential benefits when lemongrass oil is used topically for superficial fungal infections such as athlete’s foot. However, more robust, large-scale clinical trials are needed to confirm its efficacy and safety for therapeutic use in humans. In summary, lemongrass is justified for supporting or treating fungal infections based on both traditional use and moderate scientific evidence, particularly from in vitro research. Due to limited high-quality clinical data, the evidence rating is moderate (3/5).
