General Description

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.

Some Reported Medicinal Properties


Keep the bottle tightly closed in a dry place at room temperature (59-86°F or 15-30°C). Shake well before use. With the liquid dropper, add the drops to a 4 oz. glass of water, not distilled or reverse osmosis. Do not place drops in hot water. Allow the drops to sit in the water for at least one minute before drinking. Do not use if pregnant or nursing. Stop use if adverse reactions develop.

Research On NutraMedix Product

Establishment of the potential anti-inflammatory effect of the product known as Quina. The study demonstrated that Quina had anti-inflammatory effect similar to indomethycine and can be used to address inflammation from inflammatory agents such as carragenine, as observed in animal testing and as appears in specialized literature. Full Article

An acute oral toxicity study was conducted by the University of Guayaquil, Ecuador concluding that Quina did not produce toxic effects, thus the product is considered practically innocuous for humans when administered in the acute form. Therefore; studies of acute toxicity at higher doses in humans are not necessary. Full Article

Patient Reports
“I take this for babesiosis, and it is very effective. I respond better to it than the antimalarials such as Mepron, Atavaquone. Not as hard on my system, either. Started with one drop twice a day and worked up to ten. I have never taken more than ten drops twice a day (although you can). You put it in water, wait one minute, then drink. I haven’t suffered any side effects from Quina and never had a severe herx reaction from it, either.”-S.A.

“This has cleared up my foggy brain. I remember names and numbers again. My chronique fatigue has gone away . Not bad for a 70 year old gal.” – K.C

“Bloating, gas, stomach spasms – I had it all.  This stuff made me feel like I did when I was a kid.  My food was no longer my enemy.  Quina’s great!”-R.I.
