Most people are not aware of the significant body of basic science and clinical research in homeopathy. Whether you have a personal interest in research, you will inevitably know others (friends, family, or family physicians) who will ask you what "evidence" is there that homeopathy works. The books listed below are very important for this.
The Emerging Science of Homeopathy: Complexity, Biodynamics, and Nanopharmacology, by Paulo Bellavite, MD, and Andreas Signorini, MD. (Written by a professor of pathology and a homeopathic physician, this is the best book on homeopathic research. It was recently updated in 2002. Make certain to read and appreciate the two appendices.)
Homeopathic Family Medicine (an eBook), by Dana Ullman. (This eBook integrates the latest clinical research in homeopathy with practical clinical information that is useful to health and medical professionals as well as to consumers.)
Classical Homeopathy, Michael Carlston, MD (This book was published by a major conventional medical publisher, and it is a well-referenced textbook that is a solid introduction to the science and art of homeopathy.)
Homeopathy: Science or Myth, Bill Gray, MD (This is a good book on research, though it only refers to and discusses those experiments that showed that homeopathy worked; it doesn't discuss the various studies that didn't show an effect.)
For people interested in some of Dana Ullman's earliest writings, you can read his undergraduate thesis at U.C. Berkeley in 1975 on "Human Learning." Honor students at UC Berkeley who wish to have an independent major (and who do not want to have a regular generic major) are required to write a thesis. This paper on "Human Learning" provides insights into Dana's early synthetic and integrative thinking. The beginning of the article and its definition of "science" may be of special interest. Also, Dana creatively chose to use his own invented pronouns to replace the masculine emphasis of "he," "him," and "his," with "che," "chis," and "cher."
