Rooh khus (also known as vetiver or khus grass) is a type of fragrant grass that is widely used in perfumery and aromatherapy. It is native to India, and has been used for centuries in Ayurvedic medicine for its calming and cooling properties.
The plant grows up to six feet tall and has long, narrow leaves. Its roots are the main source of its fragrance, which is earthy and woody, with a hint of sweetness. The essential oil extracted from the roots is commonly used in perfumes, soaps, and other fragranced products.
Rooh khus is also used for its therapeutic properties. Its oil is believed to have a calming effect on the nervous system, and is used in aromatherapy to alleviate anxiety, stress, and insomnia. It is also used as a natural insect repellent and to treat various skin conditions.
In Indian culture, rooh khus is often used in religious ceremonies and as a natural air freshener. It is also a popular flavoring agent in food and beverages, particularly in North India.
