Thujone is primarily known for its presence in essential oils of plants like wormwood, sage, and thuja. It has been used traditionally in herbal medicine and as a flavoring agent in alcoholic beverages such as absinthe. Its psychoactive properties have led to interest in its effects on the central nervous system, where it acts as a GABA receptor antagonist, potentially contributing to convulsant and stimulant effects at high doses. Due to safety concerns, its use is regulated in many countries, especially in food and beverages. In aromatherapy, thujone-containing oils are sometimes used for their purported uplifting and cleansing effects, though with caution due to toxicity risks. It also finds use in research settings for studying neuroreceptor activity and seizure mechanisms.
