Iridology

Iridologists feel they can use the iris to distinguish between healthy systems and organs in the body, and those that are overactive, inflamed, or distressed.

Iridologists claim the iris patterns can demonstrate a person’s susceptibility towards specific diseases, show past medical problems, or indicate many health problems.

The iris has an endless number of structural features as well as an astonishing range of colors that can be used to identify a person’s uniqueness. In fact, just like a fingerprint, no two irises are exactly the same.

Those who perform iridology try to analyze the many body systems to gain a better understanding of their patients’ past, present, and probable future health concerns, including the harmful accumulations in the body’s various systems.
