Cymbopogon martinii is a species of grass in the lemon grass genus native to India and Indochina but widely cultivated in many places for its aromatic oil. It is best known by the common name palmarosa. Other common names include Indian geranium, gingergrass and rosha or rosha grass.


The essential oil of this plant, which contains the active compound geraniol, is valued for its scent and for a number of traditional medicinal and household uses. Palmarosa oil has been shown to be an effective insect repellent when applied to stored grain and beans,[3] an antihelmintic against nematodes,[4] and an antifungal and mosquito repellent.[5]

Palmarosa oil, which has a scent similar to roses, is added to soaps and cosmetics.[5]
