Yes, I'm making assumptions, just as you are. The difference seems to be that you don't realize this.
Like so many I have lost my trust in the medical establishment a long time ago. Its exponents have failed to help me towards better health and shown considerable ignorance along the way on several occasions. In my quest for health, I've read a lot about different approaches towards nutrition. All of them seem to be supported by ample scientific evidence however contradictory they are, which has somewhat shaken my trust in that kind of evidence.
That and the fact that so many people swear by the flushes make me give them the benefit of the doubt - what great risk is there anyhow? It doesn't really matter if the "stones" are Gallstones or not. A lot of people have reported alleviation of various symptoms, and that's what I'm after.
