Or more likely, it could also be you have not eliminated the conditions in your body that promote stone production (i.e. parasites or some other unknown metabolic imbalance).
I'm guessing 95% of LFers aren't even close to doing all that is required to stop producing stones because such dedication is difficult in today's world. Therefore, they always have more to flush.
The other reason these are not "soap stones" is they are identical to the stones and material found in livers and gallbladders from people who have never done a flush. How do you skeptics explain that?
Liver Flushing is not a new trend conjured from the alt health crowd. There is old medical research behind it (where Hulda got it), and I'm pretty sure German and some Euro MDs use a form of this purge for treating gallbladder instead of the knife.
