As a teacher of graduates, I have been impressed with the dissatisfaction existing with the state of Therapeutics, which appears to most physicians chaotic. I have tried in this book to give a guide in the treatment of the sick by emphasizing that blood alone cures, and that all methods used to treat disease must serve to purify it, and bring it where it is needed. I have discussed the various therapeutic methods with this idea in View and have given the essentials of each, enough I believe, for immediate use, and to serve as an introduction to special works, which the book is not intended to replace. To accomplish this, each chapter had to be short, an outline only of the vast material it represents. This applies especially to the one on drugs, almost sketchy in character, yet like the others, contain ing the essentials of this method of treatment. It has been my aim to make this book useful for every day practice. The healing force of Nature has been explained in the Intro duction. The chapter on Fresh Air contains an outline of the treatment with Air Bath, Sun Bath and Climate.
