Aromadendrene is a woody sesquiterpene hydrocarbon found in several essential oils already present in the AromaForge archive, including tea tree and curry leaf records. The strongest direct constituent evidence is still preclinical: one PubMed-indexed study reported antimicrobial activity for isolated aromadendrene and additive-to-synergistic interaction with 1,8-cineole against susceptible and resistant pathogens. Beyond that, the public literature is weighted toward identity, occurrence, and broader review summaries of the aromadendrane sesquiterpene family rather than human data.

Chemical identity and composition

PubChem resolves aromadendrene to CID 11095734 with formula C15H24 and a tricyclic aromadendrane-style sesquiterpene structure. NIST lists aromandendrene under CAS 489-39-4, while PubChem synonyms also include 72747-25-2, so the archive keeps the CAS already used in local oil files. In AromaForge oils, aromadendrene is already recorded at 4.5% in curry leaf and in tea tree composition ranges traced to ISO-style reference data.

Aroma and practical use

woodyherbalresinousherbaceousresin
  • Use the recorded woody, herbal, resinous, herbaceous, resin descriptors to explore a blend's scent character; perceived strength also depends on the other ingredients.
  • Review the flagged use concerns across every contributing oil and the selected dilution.
  • 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 2010 Eucalyptus globulus fruit-oil study reported that aromadendrene was the main compound in the oil, showed antimicrobial activity against Gram-positive bacteria including MRSA and VRE, and appeared to contribute more to the activity than 1,8-cineole or globulol.

This experimental finding does not establish benefit, dose or safety in people using this blend.

The same 2010 study reported that combinations of aromadendrene and 1,8-cineole reduced MIC values additively in checkerboard assays, while time-kill testing indicated synergistic effects.

Because the direct biological evidence is limited to in vitro antimicrobial work and review-level family summaries, archive copy should avoid therapeutic or anti-infective claims for isolated aromadendrene.

How the effects were investigated

membrane level antimicrobial signal

The available direct antimicrobial paper did not define a molecular target, but it identified aromadendrene as the most active of the major Eucalyptus globulus fruit-oil terpenoids and found stronger combined activity with 1,8-cineole in time-kill testing.

preclinicalRoute not recorded

This experimental finding does not establish benefit, dose or safety in people using this blend.

no human validated mechanism

No constituent-specific human mechanism or clinical pharmacology for isolated aromadendrene was verified in this pass.

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 (7)
  • No human clinical studies specific to isolated aromadendrene were located in the reviewed public sources.
  • Direct isolated-constituent evidence is narrow and depends heavily on one antimicrobial paper plus broader family-level review context.
  • Constituent-specific sensitization, phototoxicity, and topical-use-limit data were not verified in this pass.
  • 2026-07-13 re-verification (worker c3): a targeted search for aromadendrene (CAS 489-39-4) IFRA dermal limit and sensitization/phototoxicity data found a supplier note that it is 'not classified as a hazardous substance' but no authoritative constituent-specific numeric limit or hazard monograph; that supplier note is too weak to change sensitizing/phototoxic fields, so dermal_limit_verified remains false.
  • 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.
