Fragrant India's Ruh Khus attar or Khus absolute is produced through the distillation of the root part of the plant (vetiver grass). The roots of vetiver being a plant possess one of the most exotic aromas imaginable; a unique earthy fragrance which has captured the imagination of people for centuries. The oil of Khus/Vetiver is also referred as �Oil of Tranquillity� in India and one of the favorite ancient attars from the centuries. In some countries Ruh khus is also known as �Green Vetiver�.
