 +"Flouve absolute is a viscous, greenish-amber to brownish-yellow liquid, having a very sweet, herbaceous, tobacco-like and coumarinic odor.

However, the overall fragrance is sweet, licorice-like, root-like, somewhat mossy-herbaceous like wet underforest and meadows, of exceptional tenacity and high penetrating power.
