placebo
Significado: A substance with no therapeutic effect, used as a control in testing new drugs or given to satisfy a patient who supposes it to be a medicine.
The placebo effect, whereby patients experience real improvement simply from believing they are receiving treatment, is one of the most studied phenomena in medicine. Placebos are fundamental to randomised controlled trials, where they help researchers isolate the true effect of a drug. The term is also used figuratively for anything that offers comfort without genuine substance.
