How has alternative medicine managed to become so mainstream? This episode of Rationally Speaking features Dr. Paul Offit, award-winning specialist in vaccines, immunology and pediatrics, and author of popular books such as "Do You Believe in Magic?: The Sense and Nonsense of Alternative Medicine." Julia and Massimo interview Dr. Offit about the fight against alternative medicine, why it's still unregulated, and whether or not to tell patients about placebos.
