Iridology
Iridology is a diagnostic science in which the study of markings in specific areas of the iris are used to indicate dysfunction in corresponding organs of the body. Used by physicians, naturopaths, chiropractors and other healers, iridology is a non-invasive technique that supplies information not clearly delineated by other means regarding the condition of the body.
Based on this information, the practitioner can make recommendations for changes in diet or lifestyle as a preventative approach.
