Hi Hanna, thanks for your reply.
I think the kale theory is out... but I'm still not sure - a whole bunch more came out this morning, alot. and I fasted yesterday on juices and apple juice in preparation for a liver flush. What's coming out is almost black now, not as much greenish, and a firmer and thicker consistency. (I chewed the kale more than the way this stuff is coming out) I also have cut back on the quantity of Oxypowder I was taking, don't know if that had anything to do with it or not.
