I'm sceptic on one hand and a believer on another.
I dont believe bile ducts are able to expand to up to an inch to release stones, this is just anatomically impossible, also I spoke to a medical student who has witnessed a few autopsies and has done some preperation of liver tissue and never saw 2000 "stones". my personal opinion would be you'd have severe jaundice, if all bile ducts are closed off, so I do think they somehow solidify in the bowels gall bladder. I do know a Liver Flush expells one of the most foul smelling toxins, these stones make normal faeces smell like roses. Therefore I am positive some nasty toxins are released, I just dont think they are solidly formed in the liver.
