Discussion: What is the definition of Functional Self-healing Medicine?

My broad suggested definition of Self-Healing Functional Natural Medicine:
"All types of methodologies, techniques of non-invasive medicine (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 significant improvement (without considerable side effects) in the overall health of the patient on the long run."
