GALL BLADDER STONES (MULTIPLE STONES)

Doctors advised me operation to remove the Gall Bladder. As I donot have any pain I didn't accept it at all. Now, I wish to know the flushing procedures. From various articles I understand that Olive Oil + Lemon mix is helpful to remove the stones from the Gall Bladder. Besides this If there is something very effective kindly advice me to get out of this problem. Thanks. Rashi
