Note from Henriette: The Cinchona entry in King's is about 30 pages, and Cinchona, the plant (or bark), while used quite a lot by the pharmacists, is not really herbal anymore. So I'm not scanning the entry in King's. Nor am I scanning the Cinchona alkaloid entries (Quinine, Quinidine sulphate, Quinine bisulphate, etc.). They're simply not interesting enough for me.
However, here's links to other cinchona entries, as found on this site:
King's American Dispensatory, 1898, was written by Harvey Wickes Felter, M.D., and John Uri Lloyd, Phr. M., Ph. D.
