Hi Hanna,
How about the gallstone? I just find out about UT searching for ear infection (a very but one) and then it seems it can work on gallstone as well according to Uropaty by Martin Lara. I didn't find the book yet but I intend to buy it. http://www.shirleys-wellness-cafe.com/urine.htm
Do you have any recommendations for UT?
Best of luck
