I was told by a friend of mine who's wife suffers from a few disorders, including dibetes and bad liver function, that the geen stones are actually the olive oil. He and his wife told me originally about the Liver Flush process that you described, but later learned from a doctor that the stones she was passing were not stones. They were actually bile that had been colored by the olive oil. He commented how they were a pretty emerald color. Now this is a man who eats nothing but health foods and is well into his 60's and still does sheet metal work.
I don't want to discourage anyone from trying, because with organizations like the AMA, I don't trust any doctors. Finally, I would just say that what the doctor told my friend, could have been disinformation. On the other hand, it could have been true. Whatever you do, don't stop doing the homework. When you take matters like your health into your own hands, you have to study like a doctor and never accept anything at face value. With all due respect to Marg. I hope the Liver Flush story is true. Lord knows we sure need some alternative approaches.
