Etymology[edit]
The term psychedelic was coined by the psychiatrist Humphrey Osmond during written correspondence with author Aldous Huxley and presented to the New York Academy of Sciences by Osmond in 1957.[2] It is derived from the Greek words ψυχή, psychḗ, 'soul, mind' and δηλείν, dēleín, 'to manifest' thus meaning "mind manifesting," the implication being that psychedelics can develop unused potentials of the human mind.[3] The term trip was first coined by US Army scientists during the 1950s when they were experimenting with LSD.[4]
