Lemon grass is an aromatic tropical plant, believed to have a wide range of therapeutic effects. Lemongrass is considered by herbalists to have several useful properties, including antibacterial, antifungal, an fever-reducing effects. Some of these claims have been supported by animal and laboratory studies. More recently, lemon grass has been shown to have antimutagenic properties; that is, researchers have found that it is able to reverse chemically induced mutations in certain strains of bacteria. Like many essential oils, lemongrass is also used in aromatherapy.
