I'ts great of Spirit to continue in his efforts to prove the existance of liver/gall stones, but the proof of the pudding is in the eating. [perhaps an inapropriate metaphor]For someone like myself that has been ill for over 20 years, after being poisoned with orgarnophosphate pesticide, had tried every type of therapy that you can think of, and a few you probably have never heard of, and spent thousands of pounds on trying to get well, to be restored to health by 13 [simple, cheap] Liver Flushes has proved Dr Clark's point beyond doubt as far as I'm concerned. Dr Clark's protocol is her protocol because IT WORKS. Love and Light Deotima.
