Do you believe in "natural" cures for medical problems? - how long does grapefruit juice work

I ask because I have gallstones (long story that I wrote before, go with me, ok?). So I tried to "cure" of gallstones: 3 tablespoons olive oil 1 / 2 grapefruit juice and juice of 1 lemon (I do not know how it works, so do not ask) does not. I think it is one of the grossest things I had, makes me want to cry and vomit at the same time and I do not know if this will work. I have the "recipe" of the Internet and not a real doctor, but someone who claims that a nurse and a "healthy" (if this is the real person) image on the Internet.

Of course, I read that there are other cures "and want to know:
1) Has anyone else tried this shit, or somethingas, if so, what is it?
2) Did it work?
3) Does anyone really believe that the work (I doubt it really is)?
