Placebo effects

The placebo effect is defined as a phenomenon in which some people experience a benefit after the administration of an inactive "look-alike" substance or treatment. This substance, or placebo, has no known medical effect. 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.

Example of a placebo would be a sugar pill that's used in a control group during a clinical trial. The placebo effect is when an improvement of symptoms is observed, despite using a nonactive treatment. It's believed to occur due to psychological factors like expectations or classical conditioning.

Another example is, if a patient receives a fake pain medication in a healing environment and the healthcare provider tells the patient that they are receiving a powerful pain treatment, many patients would get releaf from their pain due to psychological reasons. Or mind plays a main role in this.
