CINCHONA BARK Cinchona officinalis
CINCHONA BARK-Cinchona officinalis
In the 1600s, cinchona tree bark was discovered to be an effective treatment for the symptoms of the disease malaria. The bark is extremely bitter and was therefore consumed in beverages, typically sweetened ones. Some beverages today that contain cinchona bark or purified quinine (though not enough to cure malaria) include tonic water, Dubonnet, Lillet, Amaro Nonino, and Fernet-Branca.

The bark available for purchase online is not labelled as to its potency. And if you read the article below or this one, you'll also find that an overdose of cinchona bark can be dangerous or fatal.
DO NOT ATTEMPT TO MAKE YOUR OWN MEDICINE USING CINCHONA BARK.
Quinine is on the United States TTB's list of "Flavoring Substances and Adjuvants Subject to Limitation or Restriction" [link]. Purified quinine such as is used in tonic water ("Quinine, as the hydrochloride salt or sulfate salt") is limited to 83ppm "in carbonated beverages as a flavor."
Cinchona bark, as is used in bitter liqueurs and tonic syrups ("Cinchona, Red & Yellow Bark") is limited to [link] use "in beverages only: not more than 83 ppm total cinchona alkaloids in finished beverage."
This means that it's not just the quinine in cinchona bark that's limited; it's the total quantity of quinine plus the other alkaloids including quinidine, cinchonine, and cinchonidine.
The TTB also states [link] on their "Pre-Import Supplemental Information" form that "Cinchona Bark may not contribute more than 83ppm of total alkaloids (Equivalent to 58ppm of quinine) to the finished alcoholic beverage." This seems to indicate that quinine is about 70% of total cinchona alkaloids.
Quinidine can have serious impacts on heart rhythm, particularly those with "prolonged QTc."
Most people will not know if they have this condition, which can be exacerbated by medications including antibiotics and psychiatric medications. The number of people with prolonged QTc can be greater than 1%, or more than 1 out of every 100 customers.
Though products with cinchona alkaloids below the legal US limit should not impact this condition, the amounts of quinidine used in homemade tonic recipes could very well impact the hearth rhythms of people with this condition. Potentially this could have life-threatening impacts.
Even in heart-healthy people, excessive consumption of very high-quinidine products could cause problems.
