Ellen Tart-Jensen, Ph.D., D.Sc. has added 25 years of research to the original Iridology Chart developed by Dr. Bernard Jensen. After spending thousands of hours studying with Dr. Bernard Jensen, working in private practice, and teaching iridology world wide, Dr. Ellen Jensen has color-coded the chart to make it easy to read each organ area and iris zone. Spinal areas as they relate to the pupil border have also been included. The reverse side of the chart lists the major organs of the body and the best vitamins, minerals, and herbs for these organs. 8.5 x 11 laminated.
