You are correct in being skeptical about the source of the stones. Why wouldn't anything produced in the small intestines not have bile init? Bile will definitely be released in response to the fats in the olive oil. We excrete about a quart of bile per day but resorb most of the bile salts excreting 30-100 ml of biel per day...more if you give yourself the runs. The ES supplies the magnesium which in turn causes the diarrhea. Thje presence of bile salts does not equal formed in liver or gall bladder. REal Gallstones sink.
