A substance found in certain mushrooms that causes hallucinations and changes in perception.
Many people have used psilocybin for its mind-altering effects during spiritual ceremonies.
Psilocybin is formed from "psilōs" (from Greek, meaning bare or bald) and "cybin" (derived from the Greek "kube" meaning head). The term refers to the chemical compound found in certain mushrooms that causes hallucinations, often associated with the bare or bald appearance of the mushroom caps.
Think of the Greek word for 'bare' ('psilōs') to remember that 'psilocybin' relates to the bare appearance of certain mushrooms that contain this hallucinogenic compound.
