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 South Asia and Maritime Southeast Asia. While both can be used interchangeably, C. flexuosus has higher solubility in alcohol[1] and is therefore largely used in the perfume industry.  Lemongrass essential oil is the quintessential air freshener, making it a popular addition to diffusers and room sprays, but also finds use in aromatic rubs and massage oils.
