Actively used in medical treatments, the placebo is an inert medication prescribed more for mental relief than for actual effect on a disorder. Originally the term placebo was a derogatory term to describe false physicians, but is now considered by some to be a vital part of understanding healing in medicine. It wasn’t until the 1970s that the true physiological implications were understood.
The result of administering placebos can produce what is known as the placebo effect. It is based on two concepts: conditioning and expectancy. Conditioning refers to a person’s preconditioned physical and physiological responses to certain stimuli. Expectancy applies to the cognitive belief that a treatment will be effective. The placebo cure rate ranges from 15-72%. Placebo effectiveness is grown by increasing treatment length and physician visits.
The Placebo Mechanism Theory explains the placebo effect in animals, which is thought to be a result of human contact. Check out the infographic below presented by NursingSchoolHub.com to learn more about the placebo effect.
