liver flush not effective??

Has anyone ever done a Liver Flush and not produced any stones? Believe me the Epsom Salts was VERY effective but there was not one stone present. I also had kidney stones the last 4-5 years and I have done the natural treatment of hydrangea root and apple juice combination multiple times and it dissolved the kidney stone. I know that because when they did the last x-ray there was no stone anymore and it was too large for me to pass. With that in mind I was wondering if that combination might have dissolved the gall stones also. Does anyone know if this might be the case/
