I would like a scientific explaination of how and why these chemicals work on. the intestine... how do the minerals interact with the intestinal wall, the stomach enzymes, digested food to promt elimination.? I would also like to know that if I took this prep on an already clean intestine would I be alble to eliminate the clear liquid? Does this liquid expand in the gut as some fiber drinks do? What causes the bloating? My doctor is not giving me these answers and I would like a source
