Just so you know, this was pioneered years ago by non-doctors. Everything you hear today about the microbiome and why antibiotics damage you, stems from this. The main guy to push this as a treatment wasn't a doctor and after helping his friend cure himself of severe bowel issues, he set up a stool bank to help other people.

Because it works, the medical establishment has regulated it. Among other things, it cures most cases of IBS and Crohn's. The first guy with a well-documented case did it in order to avoid a colonectomy and the ugly prospect of carrying a plastic bag for his poop for the rest of his life. Science backs it up, but only because it's real.
