A genus of grass characterized by its fragrant smell. In some cultures, lemongrass (also known as Cymbopogon) is said to have an aphrodisiac quality. It is also used as a preservative, a medicinal herb, and as a natural pesticide.

Personal lubricant manufacturers primarily use lemongrass for its purported libido-enhancing effects and for its pleasant fragrance. While it is generally safe, it can cause reactions in people with grass allergies. Some evidence suggests that lemongrass can stimulate menstruation, and because of this, pregnant women should not use products with this ingredient.
