The answer is: placebo.

Explanation: A placebo is a substance that lacks a therapeutic effect and is often used as a control when testing new drugs. It is typically an inert substance, such as a sugar pill, that has no active ingredients. The purpose of using a placebo in clinical trials is to compare the effects of the new drug with the placebo to determine the drug's efficacy and to account for the placebo effect, where patients may experience perceived or actual improvements in their condition simply because they believe they are receiving treatment.
