Poop Therapy

C. difficile, a dangerous bacteria that antibiotics often cannot control, is a global problem. In U.S. hospitals alone, more than 300,000 patients contract C. difficile each year, and researchers estimate that the total number of cases in the U.S. may be three million. Treatment costs exceed $1 billion a year.

But recently, fecal infusion therapy, transplanting feces from a healthy person into the gut of one who is sick, has been used effectively to cure this intractable gut ailment.

Similar approaches have been used in the past on horses and cows, and ancient Chinese medicine texts even mention giving "yellow soup" orally to human patients to cure diarrhea, which doesn't really make you want to grab a phone and order Chinese food :)
