Vetiver is famous all over the Indian Subcontinent. People may not understand it since many of them are unfamiliar with this name. Instead, it is popularly known as “Khus” or “Khus-Khus” and it is extensively used in perfumes, food, and beverage industries. This grass has a very pleasant, mild, earthy, and musky smell which has a cooling effect on the body and the mind. The dried grass and its roots are used to thatch the side panels of the water-based room and window coolers since it cools and adds fragrance to the moist air.
