I'm now reading a book called "Do you believe in magic"/ Paul Offit, it's on topic of alternative medicine. In 70's there was a very popular (and bogus) cancer cure called Laetrile (Hygrogen Cyanide) that was pushed by some doctors and organizations. Horrible stuff that caused more damage than helped but too many people were trying to sell it as a magic cancer cure. Also there were coffee enemas... My point is, if it's sold like a magic cure it potentially might be a bogus one? How many times humanity won the lottery prize and discovered something revolutionary like penecillin?
