Many authors use the term "Iridiagnosis" or "Irisdiagnosis," but I prefer to use "Iridology because I feel the science is not the last word in determining the health of a person according to the generally accepted methods. It reveals inherent characteristics of the tissues in an organ. It shows tissue changes resulting from proper or improper treatment. It is a check-up on both the person and the practitioner as to wheather the person's health is improving. It is an evaluation that can work hand in hand with natural habits of living which build health and eradicate disease.
