Iridology is a science. It can reveal disturbance in the body, can locate the disturbance and tell the iridologist at what stage the disturbance is progressing or manifesting. The iris receives and stores information about the body in the same way a computer gleans and stores information during scientific experiments. The iris actually receives signals from all areas of the body and responds to these signals by imprinting data in the iris. Iridology can reveal constitutional strengths and weaknesses, inherited strengths and weaknesses, general health levels, nutritional and chemical needs, location of toxins in the body, dietary needs and problems, the quality of the nervous system and internal organs, the response a client has to treatment, and acid levels in the body.
