Cymbopogon
Genus of grasses From Wikipedia, the free encyclopedia
Cymbopogon, also known as lemongrass, barbed wire grass, silky heads, oily heads, Cochin grass, Malabar grass, citronella grass or fever grass, is a genus of Asian, African, Australian, and tropical island plants in the grass family.[5][6][7][8][9] Some species (particularly Cymbopogon citratus) are commonly cultivated as culinary and medicinal herbs because of their scent, resembling that of lemons (Citrus limon). The name Cymbopogon derives from the Greek words kymbe (κύμβη, 'boat') and pogon (πώγων, 'beard') "which mean [that] in most species, the hairy spikelets project from boat-shaped spathes."[10] Lemongrass and its oil are believed to possess therapeutic properties.[9][11][12]

Uses

Perspective
Citronella grass (Cymbopogon nardus and Cymbopogon winterianus) grow to about 2 metres (6+1⁄2 ft) and have magenta-colored base stems. These species are used for the production of citronella oil, which is used in soaps, as an insect repellent (especially mosquitoes and houseflies) in insect sprays and candles, and aromatherapy. The principal chemical constituents of citronella, geraniol and citronellol, are antiseptics, hence their use in household disinfectants and soaps. Besides oil production, citronella grass is also used for culinary purposes as a flavoring.
Culinary
East Indian lemongrass (Cymbopogon flexuosus), also called Cochin grass or Malabar grass, is native to Cambodia, Vietnam, Laos, India, Sri Lanka, Burma, and Thailand, while West Indian lemongrass (Cymbopogon citratus) is native to maritime Southeast Asia. While both can be used interchangeably, C. citratus is more suitable for cooking.
Folk medicine
In India, C. citratus is used as a medical herb and in perfumes. C. citratus is consumed as a tea for anxiety in Brazilian folk medicine,[13] but a study in humans found no effect.[14] The tea caused a recurrence of contact dermatitis in one case.[15] Samoans and Tongans use mashed C. citratus (called moegalo and moengālō respectively) leaves as a traditional remedy for oral infections.[16][17]
FDA classification
Lemongrass essential oil has been declared generally recognized as safe in food by the United States Food and Drug Administration.[18]
Folk magic
In Hoodoo, lemongrass is the primary ingredient of van van oil, one of the most popular oils used in conjure.[19] Lemongrass is used in this preparation and on its own in hoodoo to protect against evil, spiritually clean a house, and to bring good luck in love affairs.[20]
Insect
In beekeeping, lemongrass oil imitates the pheromone emitted by a honeybee's Nasonov gland to attract bees to a hive or a swarm.[citation needed]
