This colorful power point show has very clear and detailed iris slides, showing various pupil flattening’s that relate to various areas of the spine with written explanations, and arrows pointing to the areas the pupil is flat. This will help the iridologist ask appropriate questions about a person’s back and specific areas that may be out of balance. Often the person has had an accident or injury causing that pupil area to be flat and may need chiropractic assistance or acupuncture. It also teaches the various reasons why the pupil would become enlarged, very small or even elliptical. The size and shape of the pupil can show the iridologist a great deal about that person’s spine, organs connected to that part of the spine or other more serious health concerns. Excellent for a student learning iridology or for an iridology instructor to use in the classroom.
