What really happens with this medicine?

Simply put, this medicine does two main things.

2. Dissolves existing stones: Not only that, this medicine also helps to gradually dissolve the cholesterol contained in stones that have already formed in your gallbladder and remove them from the body.

This is how this medicine helps cure gallstones without surgery.
