I agree that part of the 'stones' must come out of the gallbladder and some others must 've been formed somewhere along the elimination 'route'. What I believe it's more important here, is that, the system is placed under some kind of "stress" that activates the inner powers of our perfect machine, starting a purging/healing process, that we're notable to explain...yet, it brings a healthier state....
I declare myself a 'neoskeptic' in life, and a neophyte in the matter; nevertheless, I'm gathering enough information (and courage), to give it a try, so I can have a "hands-on" experience with my own personal facts about the results...
Skepticism: The word is derived from the Greek verb, "skeptomai," which means "to look carefully, to reflect."
A skeptic mind doesn't blindly believe, neither stubbornly denies anything.; It doubts accepted opinion, as a True fact. (“doubting” is not the same as “categorically negating”). .
skepticism is not synonim of cynicism, nor dogmatism.,
