Mechanism of action

Placebo (sucrose) is an inert substance used as a control in clinical trials. Its effects arise from patient expectation, the therapeutic context, and the natural history of disease rather than from any pharmacological action. Placebo can modulate symptoms through central nervous system pathways, particularly for conditions with subjective components such as pain, nausea, and fatigue.
