Cinchona Bark (Cinchona spp.)
Cinchona Bark is a traditional South American botanical best known as the natural source of quinine alkaloids. Historically used in bitter tonics and herbal preparations, it has a distinctly bitter taste and should be marketed cautiously because quinine-containing bark can have significant medication interactions and side effects.
Common Names: Cinchona Bark, Peruvian Bark, Jesuit’s Bark, Quinine Bark, Fever Tree Bark, Corteza de Quina / Quina / Cascarilla (Spanish)
