Use
gentian extract (Gentiana sp.) is credited with cooling, antiseptic, and anti-inflammatory properties. Studies indicate that the gentian root also has skin-lightening capacities, thanks to an ability to inhibit melanocyte tyrosinase production. All known gentian species are remarkable for their intensely bitter properties but are considered valuable tonic medicines. The root is the principal part used for medicinal and cosmetic purposes. Dried gentian root contains gentian, gentiamarin, and bitter glucosides together with gentianic acid (gentisin) and gentiopicrin.
