Quinin is derived from Peruvian or cinchona-bark. This bark, like the juice of the poppy plant, contains a number of alkaloids. These alkaloids, in turn, may react with acids, forming salts.

The Uses Of Quinin

Sulfate of quinin is the most common form of this drug. Its principal use is for the destruction of the malarial germ, and it is, therefore, the standard drug in all malarious countries. The germs of malaria, however, are not bacteria (microscopic plants, as many suppose), but minute forms of animal life. Aside from this particular use, the effect of quinin is that of a typical alkaloid, and its disturbing effect upon the nervous system, when taken in sufficient quantities, is well known.. The principal reason that we do not have more quinin addicts, or fiends as they are usually called, is due, perhaps, to its extremely bitter taste.
