cis-Thujone is the cis-configured thujone isomer usually mapped in modern databases to alpha-thujone, a monoterpene ketone found in mugwort, sage, wormwood, and related Artemisia materials. The public evidence base is driven mainly by occurrence data, neuropharmacology, and toxicology rather than by wellness-style studies. For AromaForge, cis-thujone is best treated as a safety-relevant chemotype constituent with experimental central-nervous-system activity and clear exposure-control implications.

Chemical identity and composition

PubChem and ChemEO both associate cis-thujone naming with the alpha-thujone stereochemical family, while NIST's non-isomer-specific thujone page shows how public registries can blur the boundary between the isomer pair and shared skeleton entries. In the local archive, Artemisia vulgaris mugwort records cite cis-thujone at 0-12.9% in North Lithuania oils. Because public databases expose both isomer-specific and pooled thujone records, identity language should stay explicit about whether a source means cis/alpha-thujone alone or total thujones.

Aroma and practical use

sharpherbalcamphoraceoussage-likeherbaceousmedicinal
  • Use the recorded sharp, herbal, camphoraceous, sage-like, herbaceous, medicinal descriptors to explore a blend's scent character; perceived strength also depends on the other ingredients.
  • Compare the recorded goal signals with the intended purpose, while keeping model assumptions separate from observed study outcomes.
  • Read the route, preparation and experimental context before using a study finding to choose an oil.

Reported benefits and effects

Findings retain their study context. An animal or laboratory result describes that experiment.

A Brain Research chick study found that centrally administered alpha- and beta-thujone both produced anxiogenic-like behavioral effects at 78 nmol, while only alpha-thujone reversed stress-induced GABAA receptor recruitment in that model.

The North Lithuania mugwort survey reported cis-thujone as a second dominant constituent in one Artemisia vulgaris oil, with a reported range of 0-12.9% across the seven analyzed samples.

The National Toxicology Program's thujone report and related toxicology reviews reinforce that thujone-class safety concerns focus on neurotoxicity and seizure-like findings, though those materials usually evaluate alpha-thujone or mixed alpha,beta-thujone rather than consumer-style aromatherapy use.

The clearest public safety signal is dose-related neurotoxicity, including excitation and convulsant risk, especially in thujone-rich materials.

Public records use both isomer-specific and pooled thujone identifiers, so constituent-level safety summaries should state clearly whether they refer to cis/alpha-thujone alone or total thujones.

How the effects were investigated

gaba a modulation

Thujone-class neuroactivity is best supported through interaction with GABAA-related signaling, with cis-thujone generally represented in the literature as the alpha-thujone isomer.

What this report cannot establish

  • A reported constituent percentage does not establish an effective human therapeutic dose or the amount absorbed into the body.
  • The presence of a constituent does not guarantee a clinical benefit, rash treatment or sleep improvement from a custom blend.
  • An unflagged concern or missing use limit does not establish safety for ingestion, inhalation, skin exposure or a particular person.
  • A candidate constituent interaction does not establish that two oils amplify one another at the selected proportions.
  • Constituent descriptors alone do not establish a precise top, heart or base lifetime in a finished blend.
Known data gaps (6)
  • Accessible databases map cis-thujone inconsistently across alpha-thujone, isothujone, and broader thujone entries, so stereochemical normalization may still need a later curation pass.
  • Human dose-response data specific to isolated cis-thujone were not located in the reviewed public sources.
  • Most safety and toxicology literature evaluates alpha-thujone or mixed alpha,beta-thujone rather than cis-thujone as a separately used commercial constituent.
  • The numeric dermal reference lacks source provenance; a verified flag alone is insufficient.
  • Some findings do not record an explicit exposure route; consult the linked study before applying them to a use.
  • Interaction candidates lack an attached source citation and remain unqualified.
