The basic premise of dissolving the stones and flush out the residue is a viable solution.The products are probably exspensive and weak as far as impact would go.I believe Dr. Norman Walker spoke about how malic acid would dissolve stones in the body.He reccomended mixing fresh apple and pear juice mixed 50/50 to get a good yield of malic acid.Apple cider and apple cider vinegar will be helpfull and are not very exspensive.Apple cider vinegar mixed with water along with a little honey drank throughout the day will be cheap and easy to do.Just make sure its apple cider vinegar with the mother still in it.This can be purchased at a health food store.
