I new someone with serious repetitive (daily) diarrhea. Not treatment helped and it lasted for years. Doctors had no solution. Don't know if it was Clostridium Difficile. It started after taking a medication.

One day, a solution was found on Internet. It was to eat cheese made with raw milk. After three months eating various cheese with raw milk every day, the person had no more diarrhea. This has to be done in country with strict health control on cheese production.
