Gallstones form when the liver produces excess bile, the bile is stored in the gallbladder. As the bile ducts get more and more concentrated, it crystallizes, forming stones. Parasites, bacteria and virus can also affect that area and accelerate crystallization. In the US about 20 million people are estimated to have gallstones. Women are 6 times more likely to develop them due to hormonal fluctuations. Cholesterol stones are the most common, but there are also pigment stones (formed by crystallization of calcium bilirubinate) and mixed stones associated with hemolytic disorders and infections. Even if gallbladder is removed, cholesterol gallstones can form in the main bile duct in the liver.  Adult Dose: Cleansing and Maintenance - 1 capsule three times a day - 15-30 minutes after meals - 20 days (1 bottle).
