"Peter's work on iridology is just the way I like it: commonsense, simple, and practical. After all, what good is any clinical tool if the end result is not the patient learning more about themselves, so they can adjust their lifestyle to get more quality and quantity out of life. Peter's work helps the patient learn more about themselves, so they can fine-tune their lifestyle and make better choices, to get the most out of life." Dr. Richard Schulze, ND, founder of Natural Healing Clinic and Dr. Schulze's Herbal Products Company "Through his extensive experience, as both an iridology practitioner and a gifted teacher, Peter has skilfully reorganised the teachings of past masters into a contemporary framework. With thoughtful diagnostic questions and practical recommendations, he eloquently explains that once we grasp the true essence of the iris, it can serve as a profound insight into both the inner reality of a person and the external manifestation of bodily ailments. Practical Iridology represents a milestone in the field of iridology.

Readers will undoubtedly find themselves captivated by the transformative potential of this ancient art and science."
