Insufficient Evidence to Rate Effectiveness for...
- Malaria. Cinchona bark contains quinine and related chemicals. While quinine is effective for preventing malaria and controlling its symptoms, people who take cinchona bark are exposed to risky side effects. Some of the chemicals in cinchona can slow the heart, cause constipation, and affect the central nervous system. Medical experts recommend that only purified quinine or other appropriate medications be used to prevent or control malaria. U.S. drug regulations require products containing cinchona to include labeling that states, "Discontinue use if ringing in the ears, deafness, skin rash or visual disturbances occur."
