A sugar pill is often referred to as a placebo, or a fake or inert medicine given to a patient with the belief that it will have a therapeutic effect. Other synonyms for sugar pill or placebo include dummy pill, inactive pill, non-medicinal substance, inert substance, pseudo-treatment, and simulated medication. These terms all refer to a substance that has no active ingredient and is used as a control in clinical trials or to treat conditions where there is no real medical treatment available. While sugar pills may not have real healing properties, they can be effective in helping patients who believe in their therapeutic powers as a form of psychological treatment.
