Answered by: Susan Eagles
Question from: John
Posted on: June 29, 2007

Are these products, when they are in fluid, the same?

Quinine is the alkaloid found in cinchona bark (Cinchona officinalis). If a fluid lists cinchona and quinine on the label, it may contain cinchona bark extract as well as the alkaloid quinine, extracted from the cinchona. The cinchona extract will contain quinine as well as other constituents: resins, tannins and glycosides.
