Lemon Grass

Cymbopogon, also known as lemongrass, barbed wire grass, silky heads, Cochin grass, Malabar grass, oily heads, citronella grass, or fever grass, is a genus of Asian, African, Australian, and tropical island plants in the grass family. 
Some species (particularly Cymbopogon citratus) are commonly cultivated as culinary and medicinal herbs because of their scent, resembling that of lemons (Citrus limon). Lemongrass and its oil are believed to possess therapeutic properties.
