Hi @surfing, I also like to avoid medication unless it is absolutely necessary. Mayo Clinic has more information about the gallbladder cleansing that might be helpful.

"Gallstones that cause no symptoms typically require no treatment. If you have gallstones that require treatment, discuss proven treatment options with your doctor, such as surgical removal, bile salt tablets or sound wave therapy."

Here's another article that may be helpful - "If you can't or don't want to undergo surgery and your gallstones are small, one option is to take ursodiol (Actigall, Urso), a naturally occurring bile acid that helps dissolve cholesterol stones when taken by mouth two to four times a day."

Have you discussed your concerns with your doctor?
