Fact is, for it to work as a placebo, you need to believe it will work.

What’s even wilder is you don’t have to consciously believe it, you can unconsciously believe it and it will still work! Doctors will routinely prescribe placebos and be very open about the fact that it’s just a placebo, that there is no chemical compound in the medication.

And yet, the act of taking a pill from a bottle seems to trigger something. Recent research has actually identified part of this mechanism in rat brains. There really is a part of the brain that can be tricked into releasing a set of chemicals that relieve pain, reduce inflammation and create better moods. Someday we might have a placebo pill that actually has medication in it. Wildly convoluted!
