Iridology is the study of the iris. The iris reflects past health problems as well as genetic predispositions. It can show body areas that are genetically strong and areas that will likely need support now to head off problems in the future.
An iridology examination consists of shining a bright light from the side of the eye and using a magnifying glass to identify pigmentation, folds in the tissue, the state of the fibers as well as the shading of the fibers of the iris, openings in the fibers, stress rings, etc. The exam can identify past areas of inflammation, loss of nutrients, movement of toxins, circulation issues, elevated cholesterol, and much more.
The best thing about iridology is its ability to identify areas with tissue weakness so those areas can be supported now and not become disease later.
