Cancer, Autoimmunity & the ETMS Collaborative Model
The Eclectic Triphasic Medical System (ETMS) is a comprehensive healing model developed by Donnie Yance, a Clinical Master Herbalist and Certified Nutritionist, after decades of clinical experience. Rooted in the American Eclectic herbal tradition and guided by constitutional energetics, the ETMS also integrates the latest insights from clinical nutrition, scientific research, and advanced medical testing.
​
Rather than treating illness in isolated parts, the ETMS approach works to strengthen the entire person - physically, mentally, and energetically. It’s a collaborative, individualized system designed to support those facing complex conditions like cancer and autoimmune disease, with the goal of restoring resilience and balance throughout the whole body.

How Does the ETMS Model Work?
The ETMS approach begins with a deep respect for the body’s natural intelligence. Our systems are dynamic, interconnected, and capable of healing - when given the right support. ETMS practitioners recognize that healing is not something done to you, but something created with you. The goal is to align the unique elements of your health - physical, emotional, energetic, and spiritual - into a strong, resilient foundation.
Rather than simply targeting symptoms or disease, the ETMS model looks at why illness developed in the first place. In the case of cancer, for example, treatment goes beyond attacking cancer cells. It also includes exploring the deeper terrain—your overall health, your beliefs about illness and healing, and the internal and external factors that may have contributed to imbalance.
