Is paracetamol a placebo?

Is a placebo an actual treatment?
A placebo is a medical treatment or procedure designed to deceive the participant of a clinical experiment. It does not contain any active ingredients but often still produces a physical effect on the individual. Placebos are essential to the design of reliable clinical trials.
