"flush" advice, and the lemon/olive oil thing are totally bogus and useless. Take enough olive oil and lemon, and you'll pass curds of oil that quacks will tell you are stones. It's entirely fake. Want proof? If an ultrasound shows gallstones, try those methods, pass all the weird things you want, and ask for another ultrasound (it's an expensive proof, I'll admit: but I know from experience with thousands of gallstone patients what works, what doesn't, what fools the foolable.
