Last week, one day I didn't take my lunch to work. Sicne I didn't want to eat the normal cafetaria food I bought 2 green apples. I ate those and got cramps quite bad. When I got home I had a BM that took on the shape of my small intestine. So I know whatever came out came from at least that from up in my GI tract. I know that the malic acid in the apples dissolves stagnant bile. I have taken malic acid in powder form for all of my flushes and never experienced anything like this. If this was the result of dissolving old bile, I think this would be a very powerful thing to do before a flush.
