Instead, they work on symptoms modulated by the brain, like the perception of pain. For years, a placebo effect was considered a sign of failure. A placebo is used in clinical trials to test the effectiveness of treatments and is most often used in drug studies.
For instance, people in one group get the tested drug, while the others receive a fake drug, or placebo, that they think is the real thing. This way, the researchers can measure if the drug works by comparing how both groups react. If they both have the same reaction — improvement or not — the drug is deemed not to work. More recently, however, experts have concluded that reacting to a placebo is not proof that a certain treatment doesn't work, but rather that another, non-pharmacological mechanism may be present.
How placebos work is still not quite understood, but it involves a complex neurobiological reaction that includes everything from increases in feel-good neurotransmitters, like endorphins and dopamine, to greater activity in certain brain regions linked to moods, emotional reactions, and self-awareness.
All of it can have therapeutic benefit.
