Natural occurrence
The bark of Remijia contains 0.5–2% of quinine. The bark is cheaper than bark of Cinchona. As it has an intense taste, it is used for making tonic water. Regulation in the US
From 1969, to 1992, the US Food and Drug Administration (FDA) received 157 reports of health problems related to quinine use, including 23 which had resulted in death. In 1994, the FDA banned the marketing of over-the-counter quinine as a treatment for nocturnal leg cramps. Pfizer Pharmaceuticals had been selling the brand name Legatrin for this purpose. Also sold as a Softgel (by SmithKlineBeecham) as Q-vel. Doctors may still prescribe quinine, but the FDA has ordered firms to stop marketing unapproved drug products containing quinine. The FDA is also cautioning consumers about off-label use of quinine to treat leg cramps. Quinine is approved for treatment of malaria, but was also commonly prescribed to treat leg cramps and similar conditions. Because malaria is life-threatening, the risks associated with quinine use are considered acceptable when used to treat that condition.Though Legatrin was banned by the FDA for the treatment of leg cramps, the drug manufacturer URL Mutual has branded a quinine-containing drug named Qualaquin. It is marketed as a treatment for malaria and is sold in the United States only by prescription. In 2004, the CDC reported only 1,347 confirmed cases of malaria in the United States.
Most of the Catholic priests trained in Rome had seen malaria patients and were familiar with the shivering brought on by the febrile phase of the disease. The Jesuit Agostino Salumbrino (1564–1642), an apothecary by training who lived in Lima (now in present-day Peru), observed the Quechua using the bark of the cinchona tree to treat such shivering. While its effect in treating malaria (and malaria-induced shivering) was unrelated to its effect in controlling shivering from rigors, it was a successful medicine against malaria. At the first opportunity, Salumbrino sent a small quantity to Rome for testing as a malaria treatment. In the years that followed, cinchona bark, known as Jesuits bark or Peruvian bark, became one of the most valuable commodities shipped from Peru to Europe. When King Charles II was cured of malaria at the end of the 17th Century with quinine, it became popular in London. It remained the antimalarial drug of choice until the 1940s, when other drugs took over.The form of quinine most effective in treating malaria was found by Charles Marie de La Condamine in 1737. In 1820, French researchers Pierre Joseph Pelletier and Joseph Bienaimé Caventou first isolated quinine from the bark of a tree in the genus Cinchona – probably Cinchona pubescens – and subsequently named the substance. The name was derived from the original Quechua (Inca) word for the cinchona tree bark, quina or quina-quina, which means "bark of bark" or "holy bark".
