The Cure for 97% of Diseases?

It's not the responsibility of the health care system to heal the body, only to treat certain symptoms, and then the side-effects from the treatment(s) and so on. In other words; a health concern might arise, a drug is prescribed and because the drug may block the natural processes of the body more health concerns become apparent, and more pharmaceuticals are "needed".

The body as a "whole system" can only heal through the personal development of the individual (increased knowledge of the body, better habits, improved focus on the right emotions, etc).
