Definition

Noun 1. A fragrant oleoresin: Gum labdanum is a dark brown to greenish, viscous substance. It is an oleoresin, meaning it is a natural blend of resin and essential oil, exuded from certain plants. 2. Aromatic and fixative properties: It possesses a distinctive, warm, balsamic, and slightly musky fragrant odor. Its primary use is as a fixative in perfumery, meaning it helps stabilize and prolong the scent of other more volatile fragrance components. 3. Botanical source: It is obtained as a natural juice or exudate from specific shrubs of the Cistus genus, commonly known as rockroses.
