A patient brings you a clipping from the December 11, 2011 Chicago Times with an article by Trine Tsouderos. “Thanks to a $374,000 taxpayer-funded grant, we now know that inhaling lemon and lavender scents doesn’t do a lot for our ability to heal a wound. With $666,000 in federal research money, scientists examined whether distant prayer could heal AIDS. It could not. The National Center for Complementary and Alter- native Medicine also helped pay scientists to study whether squirting brewed coffee into someone’s intestines can help treat pancreatic cancer (a $406,000 grant) and whether massage makes people with advanced cancer feel better ($1.25 million). The coffee enemas did not help. The mas- sage did.” He asks you how he can know “what works?” How do you reply?
