beta-Gurjunene is a tricyclic sesquiterpene hydrocarbon found in several sesquiterpene-rich essential oils, including spikenard in the AromaForge archive. Compared with better-studied terpenes, its public evidence base is weighted toward identity and occurrence data rather than isolated constituent pharmacology. A few mixture-level studies include oils where beta-gurjunene is abundant, but current archive-safe positioning is that beta-gurjunene is mainly a compositional and aroma marker with limited direct mechanism and safety literature.
Chemical identity and composition
PubChem and The Good Scents Company both list beta-gurjunene under CAS 73464-47-8. In the local archive it is currently tied most clearly to spikenard, where a public COA identifies beta-gurjunene or calarene at substantial abundance.
Aroma and practical use
- Use the recorded woody, dry, terpenic descriptors to explore a blend's scent character; perceived strength also depends on the other ingredients.
- 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.
salvia leucantha occurrence
A PubMed-indexed volatile-profile paper reported beta-gurjunene at 14.8% among the most abundant constituents of Salvia leucantha leaf oil, supporting its role as a recurrent sesquiterpene marker rather than a trace-only constituent.
Measured: constituent abundance
This reference does not establish a therapeutic result or a safe use level for a custom oil blend.
mixture level antibacterial activity
A PubMed snippet for a leaf-oil antibacterial paper states that the hydrodistilled oil contained beta-gurjunene at 25.5% and produced 92% inhibition, but the activity was reported for the whole oil rather than isolated beta-gurjunene.
Measured: antibacterial inhibition
This experimental finding does not establish benefit, dose or safety in people using this blend.
Use concerns and concentration limits
Sensitization concernNot flagged
Not flagged in the current model. This is not proof of absence or unrestricted safety.
Phototoxicity concernNot flagged
Not flagged in the current model. This is not proof of absence or unrestricted safety.
Oxidation concernNot flagged
Not flagged in the current model. This is not proof of absence or unrestricted safety.
Penetration enhancementNot flagged
Not flagged in the current model. This is not proof of absence or unrestricted safety.
No numeric constituent-specific use limit is available here. Missing is not an unrestricted-use clearance.
No constituent-specific human safety study, IFRA limit, or standalone toxicology paper for isolated beta-gurjunene was verified in this pass.

As a lipophilic sesquiterpene hydrocarbon with sparse direct toxicology coverage, beta-gurjunene should be treated cautiously and interpreted through whole-oil safety context rather than assumed individually proven safety.

- 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 (7)
- No strong isolated-constituent mechanism paper for beta-gurjunene was verified in this pass.
- Most accessible literature treats beta-gurjunene as one component within mixed essential oils rather than as a standalone test article.
- Constituent-specific odor and regulatory safety coverage are sparse and weaker than the identity or occurrence evidence.
- No IFRA Standard, Tisserand monograph, RIFM safety assessment, or peer-reviewed sensitization/phototoxicity study specific to beta-Gurjunene (CAS 73464-47-8) was located; identity/occurrence-only sources (GoodScentsCompany, ChemSrc, LookChem, TGSC) confirm CAS and chemical family only. sensitizing:true has been corrected to null (unsupported guess) pending real citation.
- No constituent-specific numeric dermal reference is available here.
- 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.
