I have done several hulda Liver Cleanses over the years and the first couple, as i remember had greenish and brownish results with chaff, However the next one really produced big green stones, some the size of my first thumb joint (I have big hands)and I took pics, The next one blew me away as I produced a mass of big pale jade stones. My wife took pics but alas no film in camera. I have done some since but with very little results. before the first cleanse I had developed an inflammatory response to bee stings, but I have been stung many times since with no reaction.
