Placebos are drugs that have no active therapeutic effect, yet they are often used in medicine. With a combination of physiological and neuroscientific factors, placebos can relieve a person of their symptoms even though they are not actually taking a real drug. As the cost of pharmaceuticals has risen astronomically in recent years, the need for an inexpensive, alternative to actual drugs has increased. In this review, placebos and their role in medicine will be analyzed. This will consist of a placebo’s function in pain management, usefulness in other areas of medicine, and the ethical dilemmas surrounding placebos. Future research of placebos is aimed at whether they should be separated based on their mechanism of action or based on the disease that is being treated.
