Unspezifische Therapie und natürliche Abwehrvorgänge.

During the course of the past few years there have appeared in the German medical literature not only sharp criticisms of our entire therapeutic approach—and this from excellent clinicians—but searching inquiry into the philosophic background as well as the aims, methods and results. As an accompanying manifestation, a number of interesting monographs have appeared that deal with therapy from the nonspecific point of view: Among these, the book of Königer on "Krankenbehandlung durch Umstimmung" as well as this new one of Hoff. It is perhaps to be regretted that here in America the older review of Petersen's has not been followed by a comparable interest in a field that is of wide biologic and therapeutic interest. This monograph is most interesting because it takes up in considerable detail the theoretical background that underlies not only therapy by means of nonspecific agents but the therapeutic effect of diet as well.
