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.
