It is well known in pharmaceutical double blind testing studies, k that if people are told that a drug will have a certain effect, it will, even it is only a sugar tablet and not the real test drug. The placebo effect:.

A placebo is an inactive substance, typically a tablet, capsule or other dose form that does not contain an active drug ingredient.

Placebos are often used in clinical trials as an inactive control so that researchers can better evaluate the true overall effect of the experimental drug treatment under study.

Typically, an experimental drug treatment needs to be statistically more effective than the placebo to be considered as a valid drug treatment. Including a placebo group in a study is also beneficial in evaluating treatment side effects.

Placebo effect is when a placebo treatment has a positive therapeutic effect in a patient, even though the pill or treatment is not active.

Explanation:

The placebo effect

Explanation: The placebo is an inert substance or treatment that doesn't have any therapeutic value. Examples of placebos are sterile water, saline solution and sugar pill. Sham surgery, and other procedures too.

A placebo is anything that seems to be a "real" medical treatment but in actual sense it isn't. It could be a pill, a shot, or some other types of medication.

The idea that is that your brain can convince your body that a fake treatment is the real thing and this is called the placebo effect.

Hence the placebo effect is defined as a phenomenon in which some people experience a benefit after the administration of an inactive substance or sham treatment.
