Mechanism of action

Placebo works via multiple mechanisms including expectation-induced neurobiological changes, conditioning, and natural disease progression. It activates endogenous pain-relief and reward pathways in the brain, particularly involving dopamine and opioid systems. The effect is most pronounced in subjective symptoms (pain, nausea, fatigue) and less effective for objective disease markers.
