Lemongrass (Cymbopogon citratus, Cymbopogon flexuosus) oil is a type of essential oil often used in aromatherapy, and by natural medicine practitioners for a variety of purposes, including reducing inflammation, relieving headaches, improving dandruff, and easing indigestion.
Native to islands in Southeastern Asia, lemongrass is a tall grass that grows in tropical climates. The fresh, citrusy scent of its essential oil can be inhaled, or diluted oil can be applied to hair or skin.
