Why Placebos Really Work: The Latest Science : New evidence suggests the fake drugs may cause changes in the body, not just the mind (SUMATHI REDDY, July 18, 2016, WSJ)

Studies have shown that administering placebos reduces pain and symptoms in patients with irritable bowel syndrome and migraines, even when patients know they are taking a placebo. Scientists are exploring if they can get the same result in chronic back pain and cancer-related fatigue.

Parkinson's-disease researchers discovered that stopping patients' real medication and substituting a placebo continues to ease their symptoms, likely because the body is preconditioned to trigger the same response.

Numerous studies have documented neurobiological effects that placebos have in the brain, resulting in the release of neuromodulators that can help reduce pain and symptoms of illness. New evidence suggests the fake drugs may also affect the body, in particular the immune system, according to an animal study published online in July in the journal Nature Medicine.
