Ruh Khus attar is produced through the distillation of the root part of the plant (vetiver roots). 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 centuriesvetiver’, ruh khus is an essential oil traditionally distilled from wild vetiver roots using traditional methods in Northern India.  Its characteristic color – a glowing mélange of lurid greens – actually comes from the copper vessels used in the distillation process rather than the rhizome itself.  The copper pots add a slightly metallic tinge to the aroma profile of the oil, but this is considered a desirable property.  Ruh Khus used to be exclusively distilled from wild vetiver roots, but due to unpredictable yields and the labor intensive nature of the distillation process, plantation-grown roots are increasingly used..                                                                                  Its fresh, grassy aroma is most appreciated during hot summer weather, when it provides a cooling effect.  Indian also make a very refreshing drink (khus water) from vetiver roots macerated in water.
