Hey! I took two tablespoons of Apple Cider Vinegar per day, twice a day.
Seems a lot of naturopaths recommend taking the ACV along with apple juice but grapefruit juice or any juice with pectin will do just as well. Or you can take the ACV alone. It's just that the pectin provides extra benefit for the liver. It's supposed to help soften the stones for easy passing.
You might do some research on why your liver is passing stones. Could be a lot of reasons. I think my stones were caused by the stress my liver has been under for some time processing candida toxins.
Good luck and let us know what your Dr. says about them.
