@MedicineBall - It was Doctor Max Gerson who first used coffee enemas in 1930. I got a coffee enema to detoxify my gallbladder. I had a severe reaction to something I ate and my doctor told me that it might be that my gallbladder needs detoxed. It worked and now I'm careful what I eat.
I find it fascinating that enemas were world wide back in the days of the Ancient Egyptians -- who had regular enemas. Native Americans, Greeks, the Chinese – pretty much every country. If enemas have been around that long and are that wide spread -- there must be something to them.
