"Mercury combines with bile and can cause bile from the gallbladder to become more alkaline, providing a favorable environment for parasites. These parasites can plug up the hepatic or bile duct so that needed digestive and other enzymes from the gallbladder, liver, and pancreas are not released. Gallbladder function then suffers. "
