Question for Doc Zymex/blood

I am on my 2nd go around with Zymex II. I do feel that this one is easier than the first, but it seems to cause some blood, mucus and constipation. As bad as this sounds I'm wondering if it's due to killing tapeworms? I can't imagine those enzymes creating a problem. Can they cause inflamation or is it the parasites being being disturbed ? Doc, how do you feel about enemas and colonics?
