Dr.Jarvis M.D.,author of Vermont Folk Medicine, was world authority on pH and he advocated apple cider vinegar(unpasterized,organic, raw and unfiltered) to dissolve stones.Adding unheated (not uncooked as it is cooked!)honey acts with the ACV and causes it to work even better.Two teaspoons of ACV and honey to a glass of pure water and sip.Raw apple juice can be used for taste.Do this twice a day.
