Iridology is the art and science of analyzing the delicate structure of the colored portion of the eye, the iris. The iris reveals the basic constitutional health level of an individual providing detailed information about their physical strengths and weaknesses. The iris can communicate information about all the organs of the body and the effects of crises or chronic health challenges to each, as well as tissue inflammation, and tissue integrity. Iridology is a sister-science to nutrition. Each cell,tissue, or organ in the body has specific identifiable nutritional needs. When the cell does not receive adequate nutritional values(due to faulty diet, poor absorption and digestion, environmental pollution, high stress levels, and so on), the iris reflects these conditions. Usually these depletions are noticeable in the iris long before they would be discernable through blood work or laboratory analysis, making iridology and nutritional support strong, useful tools for perventive self-care.
