I agree. I will just to copy one sentence of the first comment of tokenadult:
> [...] In actual practice, placebos only look effective when the statistical tests in a study are poor, and most especially when the symptoms are self-reported by patients. Placebos are NOT effective in treating actual disease states or improving "hard endpoints" such as reduction of all-cause mortality or major morbidity from specific diseases with verifiable physiological signs.

I didn't bother to look up the primary literature, but check Scientific American, March 2015, article by Kevin Tracey, pp. 30-35. As always, don't blame the named author for all the fluff added for the general reader.
