What is Cinchona?

Cinchona is a tree. People use the bark to make medicine.

Cinchona is used for increasing appetite; promoting the release of digestive juices; and treating bloating, fullness, and other stomach problems. It is also used for blood vessel disorders including hemorrhoids, varicose veins, and leg cramps. Some people use cinchona for mild attacks of influenza, swine flu, the common cold, malaria, and fever. Other uses are for cancer, mouth and throat diseases, enlarged spleen, and muscle cramps.

Cinchona is used in eye lotions to numb pain, kill germs, and as an astringent. Cinchona extract is also applied to the skin for hemorrhoids, stimulating hair growth, and managing varicose veins.

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."
