A ketone and a monoterpene found in nature in alpha and beta forms, which is present in the leaves of cedars (Thuja occidentalis) and many other plants (e.g., junipers, mugwort, oregano, common sage, tansy, wormwood). It acts on GABA and 5HT3 receptors and has been used topically. In contrast to popular belief, the spirit absinthe contains only minute amounts of thujone, which has long been held responsible for absinthe’s alleged psychedelic effects.
Internal ingestion is associated with convulsions.
