I can believe that "DoctorD" is a real Doctor, as my ex-Gastro-Intestinal Consultant has similar attitudes and "beliefs"... I ended up asking him if I was going to let him waste any more of my time... but he did tell me that Gallstones up to about 4mm can pass out of the gall bladder into the intestine without the risk of getting stuck in the ducts, causing obstructive jaundice etc.
Please quit wasting people's time with the general drivel.
We are bound to believe people that advocate gallbladder flush remedies that use only ingredients that can be bought from any supermarket, and who do not benefit from helping us... we would regard claims by people who sell remedies with more caution.
