    Glossary Placebo

    substance with no therapeutic effect used in clinical trials

    A placebo is a substance or treatment with no therapeutic effect, often used in clinical trials as a control to test the efficacy of new medications. It is designed to look like the actual drug being tested but does not contain any active ingredients. The placebo effect occurs when patients experience real changes in their health after taking a placebo, due to their belief in the treatment's effectiveness. This phenomenon is crucial for distinguishing between the actual effects of a drug and the psychological impact of believing one is being treated.
