I would not worry about whether stones are real/fake, what they are made of etc. Why bother about the junk stuff ? Why bother about convincing others ?
Also if the health is improving at the end of the day, what other proof is required ?
Liver cleanse is something that you do to tell your body that you love it so much that you do not want to subject it to toxic drugs or painful surgeries.
I am not discouraging you from experimenting, though. These are just my thoughts.
