"It's important to know—when it comes to everything from food to pharmaceuticals that are used for sexual attraction and arousal—you always have to factor in a large placebo effect," said Jennifer Bass, a spokesperson for the Kinsey Institute for Research in Sex, Gender, and Reproduction at Indiana University in Bloomington.
