Quinine

1895

"People in using quinine should be careful that they get a good grade of the article or that they are not being fooled altogether. In many cases an inferior product of the cinchona bark, from which quinine is made, is substituted for the real article. It is a little better than the cinchona bark and has not nearly a third of the virtue of quinine. This is called cinchonidia and can be bought for from 2 to 4 cents an ounce, just a little more than the bark itself. It is so good an imitation that the customer is unable to tell the difference except that the results will not be the same. People should be careful to get the pure drug, and the only guarantee they can have is the reputation of the man who sells it to them. — Pittsburg Dispatch.
