Researchers and clinicians have paid little attention to the fact that placebos seem to produce their own health impacts. But in a July 2 New England Journal of Medicine Perspectives piece , Ted Kaptchuk of Harvard Medical School and Franklin G. Miller from the Department of Bioethics at the National Institutes of Health, show us that there’s more to placebos than we originally thought. For example, in a study of patients with irritable bowel syndrome, patients experienced adequate symptom relief when given a placebo, compared to those who didn’t receive a placebo. That’s a common enough finding.

Seeing it administered increased the effectiveness of the medication.

During every medical visit, we experience the ritu...
