What is Iridology and How is it Used?

Iridology is a very valuable, non-invasive, assessment tool used to identify potential structural and functional imbalances within the body. By analyzing the iris of the eye for structure and color, inherited potential for and developed health conditions within the body are revealed. Iridology is not a new science. It has been traced back approximately 3,000 years and is currently used by many doctors in European countries as a regular part of diagnosis. It is part of a larger family of the numerous branches of natural healing. It is becoming more and more widely recognized in the United States as a helpful assessment tool.

Areas of the body that lack vitality to resist illness can be determined through iris analysis, and then supported by good nutrition or other natural methods. And, because Iridology shows genetic predispositions, preventive care can be introduced.
