Chapter 1.6 Placebo

jeffril salazar


A placebo is an inactive, fake, or "dummy" medication or treatment designed to resemble a drug or treatment and given in the same way. Any improvement in health that is measured, observed, or felt after the placebo is given is called the "placebo effect".

In clinical trials, a placebo may be given to one group of participants instead of the active drug or treatment in order to assess whether the latter is actually effective.
