Iridology, also known as iridodiagnosis, is an alternative medicine practice in which patterns, colors, and other characteristics of the iris are examined for information about a patient's systemic health. Practitioners match their observations to iris charts which divide the iris into zones that correspond to specific parts of the human body. The eye, therefore, acts as a "window" into the body's state.
Iridology complements all therapeutic sciences because it provides the vital information needed in order to establish the root cause of ailments, thus revealing the appropriate treatments required.
