Saffron, botanical name: crocus sativus, is the most expensive spice in the world. Derived from the dried stigmas of the purple saffron crocus, it takes anything from 70,000 to 250,000 flowers to make one pound of saffron. Moreover, the flowers have to be individually hand-picked in the autumn when fully open. The word perfume comes from the French par fume, meaning through smoke, as it was common to burn the oils in order to gain access to the essential etheric qualities released by burning. All plants are comprised of carbon-based matter. Attar perfume oils are a specific type of fragrance product derived from natural plant substances, both single ones, and those blended together carefully to produce remarkably rich scents. Although some attars are simply individual oils, which on their own are suitable for fragrance use, such as Amber, Sandalwood or Patchouli, they are usually composed of careful blends of various oils, resins and concretestwo or moreplaced in a natural base or carrier oil. For external use only.
