History

The genus Cinchona contains about forty species of trees. They grow 15-20 meters in height and produce white, pink, or yellow flowers. All cinchonas are indigenous to the eastern slopes of the Amazonian area of the Andes, where they grow from 1,500-3,000 meters in elevation on either side of the equator (from Colombia to Bolivia). They can also be found in the northern part of the Andes (on the eastern slopes of the central and western ranges). They are now widely cultivated in many tropical countries for their commercial value, although they are not indigenous to those areas.

The dried ground bark of the cinchona plant has been used for centuries for the treatment of malaria, fever, indigestion, mouth and throat diseases, and cancer. The name cinchona is said to be derived from the Countess of Chinchon, the wife of a viceroy of Peru, who it was long believed was cured in 1638 from a fever by the use of the bark; however, the story has been widely disputed. Formal use of the bark to treat malaria was established in the mid-1800s when the British began the worldwide cultivation of the plant in order to assure the continuing availability because the plant was in danger of extinction in some regions because of the harvesting of wild populations.

Extracts of the bark have been used to treat hemorrhoids, to stimulate hair growth, and to manage varicose veins. Quinine has been used as an abortifacient. Extracts of cinchona have a bitter, astringent taste and have been used as flavoring for foods and beverages. Although the use of quinine for the treatment of malaria has been largely supplanted by semisynthetic antimalarials, its use persists in some regions of the world.

Tribal and Herbal Medicine Uses

Cinchona, or quinine bark, is one of the rainforest's most famous plants and most important discoveries. Legend has it that the name cinchona came from the countess of Chinchon, the wife of a Peruvian viceroy, who was cured of a malarial type of fever by using the bark of the cinchona tree in 1638. It was supposedly introduced to European medicine in 1640 by the countess of Chinchon, even before botanists had identified and named the species of tree. Quinine bark was first advertised for sale in England in 1658, and was made official in the British Pharmacopoeia in 1677. Physicians gave credit to the drug and, because of its effectiveness with malaria, it was recognized officially even while the identity of the tree species remained unknown. Several years after the "Countess's powder" arrived in England, it arrived in Spain. There, quinine bark was used by the Jesuits very early in its history and due to the influence of the Company of Jesus, the newly named "Jesuit's powder" became known all over Europe. When the plant was finally botanically classified almost one hundred years later in 1737, botanists still named it after the countess for her contribution. Throughout the mid-1600s to mid-1800s quinine bark was the primary treatment for malaria and it evidenced remarkable results. It was also used for fever, indigestion, mouth and throat diseases, and cancer.

Natural quinine bark is still employed in herbal medicine systems around the world today. In Brazilian herbal medicine quinine bark is considered a tonic, a digestive stimulant, and fever-reducer. It is used for anemia, indigestion, gastrointestinal disorders, general fatigue, fevers, malaria and as an appetite stimulant.

Other folk remedies in South America cite quinine bark as a natural remedy for cancer (breast, glands, liver, mesentery, spleen), amebic infections, heart problems, colds, diarrhea, dysentery, dyspepsia, fevers, flu, hangover, lumbago, malaria, neuralgia, pneumonia, sciatica, typhoid, and varicose veins.  In European herbal medicine the bark is considered antiprotozoal, antispasmodic, antimalarial, a bitter tonic, and a fever-reducer. There it is used as an appetite stimulant, for hair loss, alcoholism, liver, spleen, and gallbladder disorders; and to treat irregular heartbeat, anemia, leg cramps, and fevers of all kinds.   

In the U.S., quinine bark is used as a tonic and digestive aid; to reduce heart palpitations and normalize heart functions; to stimulate digestion and appetite; for hemorrhoids, varicose veins, headaches, leg cramps, colds, flu, and indigestion; and for its astringent, bactericidal, and anesthetic actions in various other conditions.
