Hi John

The gallbladder squirts bile into the system like a fuel injector. Stones form because they are forming in bile in the gall bladder. Nothing gets into the bladder except the body creates bile and stores it there. Often there is dust or small stones. What this "liver flush" misunderstanding does uses consumed epsom salts to relax and open the ducts, then a dose of lemon juice and olive oil forces the gall bladder to eject bile more forcefully than usual. This flushes out stones. The liver produces capsules from the oil - which are mistaken as blockages flushed from the liver.
