Numerous homeopathic professionals have for a long time been asking me to write 'my materia medica.' They feel that the information I have provided in various courses over the years should reach a wider audience. To date this information has been available to only a limited number of homeopathic physicians. I have postponed this Herculean task for many years in order to create the necessary circumstances to do justice to such a tremendous job, namely, to communicate my experience, knowledge and understanding of our materia medica.
