Lemongrass is a plant. The leaves and the oil are used to make medicine. Lemongrass is commonly taken orally, applied directly to the skin, or inhaled as aromatherapy for many different conditions. But there is limited scientific research to support any of its common uses.

In food and beverages, lemongrass is used as a flavoring. For example, lemongrass leaves are commonly used as “lemon” flavoring in herbal teas. In manufacturing, lemongrass is used as a fragrance in deodorants, soaps, and cosmetics. Lemongrass is also used in making vitamin A and natural citral.
