The improvements from okeechobee Placebo are demonstrably real. We don't always understand why/how, but... the sugar pill, for example, in combination with your body and mind are very literally resulting in improvement. Placebo does not mean fake nor tricked. The efficacy is absolutely fascinating, though.

That is only true for subjective symptoms like pain or anxiety, or for objective symptoms where there is some measure of conscious control, like blood pressure or pulse.

But there is no proof whatsoever of any kind of real placebo effect for body functions with no direct conscious control, such as immune function improvements from placebos.
