The term 'Sugar Pill' is a synonym for the word 'PLACEBO', which is a medically inert substance or procedure prescribed to a patient in order to have a psychological effect. Placebos are often used in clinical trials to test the effectiveness of a drug or treatment, as the patient's belief in the treatment can have a positive effect on their health. Placebos are also used in everyday medical practice, as some patients may find relief from symptoms even when taking a PLACEBO.
