 diet      |      iridology      |      purification      |      regeneration 

The Master Iridologist course combines training in the foundational principles of natural medicine, and an in-depth study of food as medicine, for purification and regeneration, and for preventative self care, alongside the visual language of the iris. Students learn how to assess constitutional strengths and weaknesses, systemic and mind-body dynamics and the inherent pathway to both health and disease within each individual. 

Iridology, Naturopathic Principles, Holistic Anatomy & Physiology and Healing Diets are Taught In-Depth:

Discover how purification, regeneration and transformation brings light, clarity and change to the iris, along with profound improvements in health and wellbeing. Experience the profound benefits of dietary and lifestyle changes, herbal medicine and supportive therapies, guided by Iridology, in your own self-healing module, as you directly experience the teachings and become an inspiring, authentic guide for others. As you embody understanding of your own iris, you gain an in-depth understanding of how the iris mirrors our multitudinous layers of self: physical, emotional, social, mental and spiritual, in a way that creates a truly holistic approach to self-healing and natural practice. 

Train with Bonny Casel ND, MIr, a leading Master Iridologist who has personally studied with Iridology pioneers Dr. John Christopher, Dr. Bernard Jensen, Harry Wolf, Dorothy Hall, Farida Sharan, and Denny Johnson.

Immersion Details


This 5 day Immersion integrates the philosophy and practice of traditional Naturopathy, with current understanding of holistic systemic anatomy and physiology, how the body develops acute and chronic disease and the role that the eliminative channels play in increasing health and vitality. Naturopathic therapies are introduced to support elimination, relieve detox symptoms, increase strength and vitality, support constitutional strengths and weakness and balance elemental energetics.

Iridology studies begin with iris structure, markings, body systems, eliminative channels and in-depth exploration of constitutional types. Iris presentation of mind-body dynamics and inherent pathways to health and disease are considered in the context of heart-brain coherence, psychoneuroimmunology and systemic mind-body healing.

Course topics include:

∙ Philosophy and principles of natural medicine in practice
∙ 9 Pillars of Prevention
∙ Consultation skills
∙ Creating Holistic Naturopathic programmes
∙ The 5 Elements and Naturopathic Therapies
∙ Iris Structure and Markings

Each student's iris will be photographed and analysed as a group, and we will create an integrated self healing programme for each student that includes systemic herbal medicine, diet (cleansing and health building), preventative care, essential oils, flower essences, mind-body dynamic education and naturopathic therapies.

This Immersion is open to all students enrolled in a certificate or diploma course, as the course content is profoundly enriching to all areas of natural medicine study and practice.
