Aroma: Animalic, resinous, sweet, balsamic, leathery, notes of amber and ambergris. Several fragrant oils are made from Rock Rose, Cistus ladanifer. Labdanum Absolute is from resin whereas Cistus essential oil is steam distilled flowers, leaves, and sometimes branches. When resin is steam or hydro-distilled, rather than solvent extracted like with this Labdanum Absolute, the result is Labdanum essential oil. An easy way to remember the difference: Labdanum is from resin, Cistus is from vegetation.
