Quinine is made from what is called Peruvian bark, found growing in sections of central and northern South America. There are three kinds of the bark -- white, yellow, and red. It is the king of anti-periodics, and a deadly antagonist to malaria in all its forms. It should be handled with care as it often produces permanent injury, improperly given. I have been careful in giving it, and have used it in over a thousand cases, and only had one case of quininism. It is best to get some good common sense doctor to prescribe it when thought to be indicated.

How to take it to break chills. Commence eight hours before the time for the chill to come on, and take five grains every two hours in water or milk. Repeat it again the seventh day in three grain doses, the fourteenth day in two grain doses, the twenty-first day in one grain doses. This will cure any case of ague.
