The Active Ingredient Is: Cinchona Bark

Cinchona bark is a botanical material used traditionally for its historic medicinal properties. This product uses an alcohol-water tincture of Cinchona calisaya bark as the active component. The form is a ready-to-use botanical extract derived from the bark of the Cinchona calisaya tree.

This formulation comprises only Cinchona calisaya bark with alcohol and water as solvents, designed for rapid oral absorption within a tincture. The emphasis is on traditional botanical preparation rather than isolated compounds.

What Does Cinchona Bark Do?

Quinine-containing cinchona bark has demonstrated effectiveness against malaria in medical contexts where high-purity alkaloids are used, according to historical medical literature. Scientific research suggests this traditional bark source has been explored for such medicinal contexts, though modern dietary supplement dosages lack confirmed clinic-supported benefits.

Dr. Greenwood of University of London found that cinchona bark is historically linked with quinine, highlighting its storied origin within traditional medicine.
