means A psychoactive substance, often plant-derived, used in a spiritual or ritual context to provoke mystical or transcendent experience.

from A modern coinage from the 1970s, built from Greek roots: 'entheos' (god within, the same root that gives us 'enthusiasm') plus 'gen' (to generate). Scholars and writers studying psychedelics deliberately invented the word to replace older, baggage-laden terms like 'hallucinogen' or 'psychedelic' — they wanted language that honored ritual and sacred use rather than framing these substances purely as drugs of distortion or recreation.
