Discussion: Currently, there is no clear definition of what self-healing functional medicine is.

Self-healing Functional medicine eliminates the causes of the disease rather than its symptoms. Natural therapies are often synonymous with self-healing functional medicine.

My broad suggested definition of Self-Healing Functional Natural Medicine:
"All types of methodologies, techniques of non-invasive medicine, used to eliminate the causes of the disease, using mainly herbal drugs and natural supplements for the prevention, diagnosis, and treatment of diseases of the body, and mind, which can bring about a proven and significant improvement (without considerable side effects) in the overall health of the patient on the long run."
