Iridology is the study of the coloured part of the eye, the Iris. It has been used as a diagnostic tool for centuries in China and Europe and was brought to the west by Ignats von Peczeley, a German doctor, late last century. The different shapes, colours and textures visible with an iris torch can offer insight into past illnesses, present problems, in addition to general constitutional strengths and weaknesses.

Each region of the iris reflects a certain part of the body. The centre of the iris displays signs that reveal the health of the central part of the body, the middle regions reflect tissues slightly further out to the periphery and so on. The last region, the skin and circulation, is represented by the border of the iris and the white part of the eye.

The use of Iridology is a highly valuable addition to 'fine tune' a Naturopath's analysis and treatment measures.
