Lemongrass🌾

What It Is?

Lemongrass is an aromatic herb derived from plants in the Cymbopogon genus and has been used for centuries in traditional Asian and African medicine. It contains powerful bioactive compounds, including citral, geraniol, and flavonoids, which contribute to its calming, digestive, and antimicrobial effects.

Lemongrass is best known for its ability to promote relaxation, support digestion, and fight harmful microorganisms, and is commonly consumed as a tea or used in essential oils for overall wellness.
