Bernard Jensen, who pioneered Iridology in the United States, presents a basic introduction to this science which analyzes the delicate structures of the iris to reveal and locate inflammation in the body. Readers are given an explanation of how the chart works, including detailed illustrations of iris topography showing individual systems charts, and over two dozen color photographs of irises diagnosing stages of different ailments. This book supports Jensen's belief that iridology is an important element in the total, holistic health care program.
