Thankfully, the brain is trainable.
Today, placebos play a crucial role in medical studies in which some participants are given the treatment containing the active ingredients of the medicine, and others are given a placebo. These types of studies help tell researchers which medicines are effective, and how effective they are. Surprisingly, however, in some areas of medicine, placebos themselves provide patients with clinical improvement.
Despite their effectiveness, there is stigma and debate about using placebos in US medicine. And in routine medical practice, they are rarely used on purpose. But based on new understanding of how non-pharmacological aspects of care work, safety and patient preferences, some experts have begun recommending increasing the use of placebos in medicine.
Placebos are such a problem for the enterprise of drug development that a company has developed a coaching script to discourage patients who received placebos from reporting benefits.The power of the placebo comes down to the power of the mind and a person’s skill at harnessing it. If a patient gets a tension headache and their trusted doctor gives them a medicine that they feel confident will treat it, the relief they expect is likely to decrease their stress.
A field called “Mind Body Medicine” developed from the work of cardiologist Herbert Benson, who observed those monks and other experts mastering control over automatic processes of the body. It’s well understood in the medical field that many diseases are made worse by the automatic changes that occur in the body under stress. If a placebo interaction reduces stress, it can reduce certain symptoms in a scientifically explainable way.
