Lemon grass has a wonderful citrus flavor and can be dried and powdered, or used fresh. The stalk itself is too hard to be eaten except for the soft inner part. However, it can be finely sliced and added to recipes. Sabai Thai's Tom Yum Soup is a very popular dish, ingredients of which include thickly cut stalks of lemongrass which give it a very distinct strong flavor.

For medicinal purposes, lemon grass is used in aromatherapy for its calming effect to help relieve nervous tension and stress, plus its great for treating colds.
