The concept of treating colon diseases with fecal matter originated in India. Charak Samhita and many other ancient Ayurveda text that date back to more than 3,000 years recommend intake of cow dung and cow urine for multiple stomach-related disorders. Fourth-century Chinese medical literature also mentions use of fecal matter to treat food poisoning and severe diarrhea. Twelve hundred years later Ming dynasty physician Li Shizhen used "yellow soup" (aka "golden syrup") which contained fresh, dry or fermented stool to treat abdominal diseases. "Yellow soup" was made of fecal matter and water, which was drunk by the person.
