One thing is clear to me. To effectively treat a person with a complex disease you have to treat the person not the disease. Why? Because the uniqueness of each individual and how they present and what they personally need to do to get control of their health can be unique.
This is important when treating complex conditions, because balancing the functional health of an individual is unique. How the digestive tract, adrenal glands, liver, lungs, blood sugar metabolism etc. perform functionally is different for different people.
When a patient can get some control over how they feel through health-style change or taking an herb or supplement than they are on the road to healing. What will effect that control is different for everyone.
