Iridology is the practice of analyzing the delicate structures of the iris, the portion of the eye that carries color. The iris represents a communication system capable of handling an amazing quantity of information. This reveals itself in the character of the individual iris fibers.
Iridology analysis reveals inflammation, where it is located, and in what stage it is manifesting. The iris records body constitution, inherent weaknesses, levels of health and the transitions that take place in a person's body according to the way he or she lives.

The iris is the most complex tissue of the body meeting the outside world. It is an extension of the brain, being incredibly endowed with hundred of thousands of nerve endings, microscopic blood vessels, muscle and other tissues. It is connected to every organ and tissue of the body by way of the brain and nervous system. The iris is like a microcomputer readout of bodily function and condition, a miniature map showing the most remote portions of the body by way of nerve reflex responses. Nerve fibers in the iris respond to changes in body tissue, and show in the iris before symptoms occur.
