Hahnemann’s work on chronic disease may be considered a continuation of his Organon; the medicines which will follow the present volume may therefore be considered a continuation of his materia medica pura. Hahnemann developed the principles and rules which ought to prevail in the treatment of chronic diseases.
This book will be succeeded by an account of those remedies which Hahnemann especially employed in the treatment of chronic diseases and which are called as antipsorics. In the book, Hahnemann shows that most chronic diseases originate in a common source and are related to each other. A special class of drugs is designated by Hahnemann as “anti-psoric” which could be used in the treatment of those diseases. The common cause of most chronic diseases according to Hahnemann is Psora.
In the treatment of chronic diseases, Hahnemann has been taught by experience to give preference to anti-psoric remedies. This preference is not theoretical and is constantly subordinate to the general principle, which is further explained in detail in the book.
