Hi Sophie19,
It is interesting, that you are asking the same Q as I have been thinking some time.
This , of cause, doesn't constitute a science. Far from it.
Further more, there are probably another 100 or more theories, how it happens, after I publish my theory.
I can't believe, that "stones" up to an
inch can travel out of liver or a callbladder thru relatively narrow ducts.
But possibility exist, that small blobs of cholesterol balls can travel out thru the ducts. Some of them can have a calcified nucleus. As soon as they enter to the digestive track they will conclomerate for some reason in the presence of some loose bile, acid citrus juice and stomach acid to form those bigger "stones".
My understanding is much the same as yours, what ever happens there, brings toxins and unwanted garbage out of the liver/callbladder and therefore is beneficial & improves health.
Have a nice day
