What are placebo and nocebo effects?
The placebo effect is the phenomenon where a subject experiences an effect from an inactive substance or fake treatment, which is called a placebo.
A placebo, in turn, is a substance or treatment that has no effect. Examples of placebos – sugar pills, consumable liquids or solids, saline injections, and fake surgeries.
The placebo effect is a therapeutic benefit or apparent side effect from a placebo. Alternatively, it is a treatment with the exact composition of inactive ingredients or the same steps as the therapy, minus the active substance or procedure.
However, some scientists refer to a therapeutic or beneficial response as the placebo effect and side effects or a negative response as the nocebo effect (negative placebo). The nocebo effect also includes withdrawal symptoms some patients experience after discontinuing a placebo treatment.
ℹ️ The term "placebo" became part of medical jargon in the late 18th century.
