I´ve learned from someone in this forum that it is a gopod idea to keep Gallstones in a jar in the freezer. Actually I´ve got two jars full oif stones.
Yesterday I took two stones out. Put one in water and another one inside Chanca piedra Tincture. After a few hours the one which was in the Chanca Piedra was completely melted and the other one was just the way it was before.
So, I guess I got another confirmation of how efficient Chanca Piedra is. Good luck everyone!!
