Overview: Lemongrass is a tall, coarse grass with a strong lemon taste used for cooking, medicinal teas, and potpourri. Lemongrass stalks are commonly used in the cuisines of Africa, the Middle East, and Southeast Asia. Lemongrass is native to Sri Lanka and South India and is now widely cultivated in the tropical areas of America and Asia. Its oil is used as a culinary flavoring, a scent, and medicine. A tea made from the leaves of West Indian lemongrass has been used to treat fevers, colds, and upset stomachs. Lemongrass is also a folk remedy for coughs, consumption, flu, gingivitis, headache, and vascular disorders. Lemongrass is principally taken as a tea to remedy digestive problems, diarrhea, and stomach ache. It relaxes the muscles of the stomach and gut, relieves cramping pains and flatulence, and is particularly suitable for children. In the Caribbean, lemongrass is primarily regarded as a fever-reducing herb. It is also applied externally as a poultice or as diluted essential oil to ease pain and joint stiffness. The tea has diuretic properties and can help with urination difficulties and water retention. Lemongrass oil is also popularly used as a massage oil to relieve sore muscles. Lemongrass essential oil, like many essential oils, has some degree of antimicrobial activity and is used as an insect repellant as well.
