Quina is an extract produced from the bark of Cinchona calisaya, a tree from South America that is found between 1,400 meters and 2,800 meters above sea level. Quina has been used for centuries by native South Americans to treat a number of illnesses including malaria, cancer, fever, dysentery, typhoid, pneumonia, etc. It was one of the first South American medicinal plants to become known outside of the Americas. It was first used in Europe in the mid- 1600's and recognized by the British Pharmacopoeia in 1677. Quinine, one of the four alkaloids in Quina known to have antimalarial properties, has been used to produce medicines to treat malaria for nearly 200 years. Malaria strains have mutated rendering these drugs far less effective causing researchers to re-evaluate the medicinal properties of whole plant extracts of Cinchona species such as Quina. Quina is utilized by some health care professionals in the U.S. as an important component of a Lyme disease protocol. It has been found to be very effective in treating Borrelia burgdorferi, the bacteria that causes Lyme disease, Babesia and many of the coinfections that are usually associated with this condition.
