In Biology, a placebo refers to a substance or treatment that has no therapeutic effect but is used as a control in experiments or clinical trials. It is often administered to assess the efficacy of a new drug or treatment by comparing the effects experienced by participants receiving the placebo against those receiving the actual treatment. The placebo effect can lead to real physiological changes in patients, highlighting the role of mental and emotional factors in health and healing.
