Gall stones show up in ultra sounds. Not xrays. The fear for me comes with NOTHING coming out after the oil. I did one twice and I was sick all night both times because nothing moved out. Not the oil and hardly anything else. I had just come off a fast and colon cleanse. It was crazy. so I am not ready to do another cleanse. How well will the herbs work? I hope well enough because the fear is not from epsom salts but a painful agonizing night because my body wants to reject the oil or something and cannot get rid of anything.
