Mechanism of action

Placebos work by activating the patient's expectation and belief in treatment, which can modulate pain perception, immune function, and symptom severity through neurobiological pathways. The placebo effect involves both conscious psychological processes and unconscious physiological mechanisms, including endogenous opioid release and autonomic nervous system modulation. This effect is particularly pronounced in conditions with subjective symptom components such as pain, nausea, and fatigue.
