The gallstones are separated from any waste product such as the bile, bile tubes and are extracted near the liver. Washed with cold water in order to remove any blood or other imperfections. They are then stored in a dark, well air conditioned, room, at 20°C, for two to three weeks, where they dry. In order to dry them more effectively and to avoid them sticking together they are flipped to another side regularly. After the end of the drying process, the stones are vacuum packed and sealed.
