I bought the liquid/pure chanca piedra because I had Gallstones found on an ultrasound and after 3 weeks of taking a minimum dose I started to feel a little nauseous. I was laid out for about a day (thought I had a stomach flu) but on that day I actually passed gallstones. I guess the nausea was my body attempting to clear/get rid of the gallstones. They were yellow and soft (not to be graphic). I am ecstatic!!! And hope this clears my gallbladder and helps it to function efficiently so I can feel good/have energy. Happy!!! Foffie aol com if you have any questions.
