Honestly, I would be very wary of doing something like this. So many people carry parasites that are hard to detect, even with the best labs around. If your gut is already compromised, those parasites could easily dig in and do some serious damage. And also, how will you know that someone else's fecal flora is going to work for you? Every body is unique and the flora that makes someone "healthy" could make someone else sick. This is a new therapy. I would like to see a LOT more evidence before I would dive in to mixing poo in my blender.
