Just saw this.  Gerson therapy is a juicing diet.   The idea is to activate one's own healing powers of the body by using natural and organic juicing to flood the body with natural nutrient.  A  a clean detoxing type diet.  It also includes coffee enemas.  SOOOOOO not for the faint of heart, so to speak.  Idea is to clean out the body and provide a basis for the body to heal itself and not just treat symptoms. Started by a Dr. Gerson decades ago trying to deal with hi sown health problems, not sure what they were.  I researched few years  ago when I was dealing with some health issues.    I juiced and cleaned up my diet and that alone sure helped me, but Gerson is a whole program.  There is a Gerson Institute  and I think they have clinics. Sure they are on the web somewhere.
