Word: Active Placebo
Definition:
An active placebo is a type of treatment used in medical research. It looks like the real drug being tested and can cause some noticeable side effects, but it does not have the same effect on the illness or condition as the real drug. Researchers use active placebos to see if the effects of the actual drug are stronger than what people feel just because they think they are getting treatment.
