All of the Edgar Cayce readings, with few exceptions, were given for individuals with different needs. This probably explains why there are often slight variations in treatment, formula, dosage, manner of application, etc., even between readings on the same subject. Certain methods, products, and formulas, however, were recommended so repeatedly and emphatically that they have almost become specifics for certain types of disorders. Much of the information in The Physician's Reference Notebook was the outgrowth of physicians' working with these specifics.
The Edgar Cayce readings, though, should not be viewed as a do-it-yourself doctoring manual. Any of these suggestions for treatment of disease should be used under the supervision of a professional.
Finally, in the concepts of health and healing in the Edgar Cayce readings, one principle that predominates is that the health of the body, mind and soul are so closely interrelated that it is rarely of value to treat any one of these aspects without also giving some attention to the state of the other two. The reader is reminded that although this volume deals primarily with the physical aspects of health, the mental and spiritual are equally important in a holistic approach to health.
