I am practitioner of more than 30 years' standing, and currently also the Course Director for Herbal Medicine at the College of Naturopathic Medicine (CNM), of which I am also the Academic Director. Publications include "Practical Iridology" (2004), a chapter on Western Herbal Medicine in "Reshaping Herbal Medicine" (2005), and several training manuals in Herbal Medicine, Iridology and Holistic Iridology. I am co-director with my partner, Anji Jackson-Main, of the Natural Centre in Cambridge, and of the College of Holistic Iridologists. In my practice I combine Herbal Medicine and a multi-disciplinary Naturopathic approach using the diagnostic insights of Holistic Iridology, which also takes in an understanding of the role of emotion, thoughts and beliefs in creating health.
