CONSTITUENT REPORT

Carvone

monoterpene ketoneCAS 99-49-0

Carvone is a well-known monoterpene ketone that helps define the aroma of spearmint, caraway, dill, and other carvone-rich oils in the AromaForge archive. Public evidence is strong for identity, flavor/fragrance use, human metabolism, and enantiomer-specific odor context, while the bioactivity literature is much broader but mostly preclinical. The current source-grounded picture supports describing carvone as a high-recognition aroma constituent with antimicrobial, anti-inflammatory, and sensory-receptor research signals, while avoiding medical claims and noting that even JECFA's current flavoring specifications for the separated d- and l-forms remain tentative pending completion of safety evaluation.

Chemical identity and composition

PubChem lists the parent carvone record as CID 7439 with formula C10H14O. Carvone is routinely discussed as two enantiomers with different sensory associations: JECFA's d-carvone entry describes a caraway-like odor, while the l-carvone entry describes a spearmint-like odor. Archive oil files already reflect that split, with spearmint records pointing to the levorotatory form and caraway or dill records using the generic parent constituent.

Aroma and practical use

mintycaraway-likesweetspicyherbalherbaceous
  • Use the recorded minty, caraway-like, sweet, spicy, herbal, herbaceous 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.

A 2022 systematic review identified ninety-one experimental carvone studies across ten pharmacological-activity categories, but concluded that many included studies had uncertain risk of bias and that more mechanism and safety work is needed.

A 2013 cell study reported that (-)-carvone acted as a TRPV1 agonist in dorsal root ganglion neurons and recombinant human TRPV1-expressing cells, with an EC50 around 1.3 mM in the HEK293 model.

A 2001 human metabolism study found both S-(+)- and R-(-)-carvone were metabolized mainly to dihydrocarvonic acid, carvonic acid, and uroterpenolone, with no major qualitative difference between the two enantiomers.

A North American Contact Dermatitis Group analysis reported positive patch tests to carvone in 188 of 24,124 tested patients, with 73.3% of the positive reactions judged currently relevant and common exposure sources including personal care products and food.

How the effects were investigated

TRPV1 agonism for (-)-carvone

A PubMed-indexed cell study reported that (-)-carvone increased intracellular calcium in dorsal root ganglion neurons and TRPV1-expressing HEK293 cells, with blockade by capsazepine and ruthenium red supporting TRPV1-channel activation.

The 2021 review summarizes antimicrobial studies that attribute carvone activity partly to cell-membrane disruption and ultrastructural changes rather than to one single validated human target.

human_oxidative_and_reductive_metabolism

Human metabolism studies found carvone is converted mainly to dihydrocarvonic acid, carvonic acid, and uroterpenolone, with minor carveol and dihydrocarveol formation and little evidence of major enantiomeric differences in overall metabolite identity.

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)
  • The archive-level parent record covers carvone broadly, but the literature and regulatory specifications often separate d- and l-carvone; users should not assume every result applies identically to both enantiomers.
  • Much of the benefit-oriented carvone literature remains preclinical and heterogeneous in quality.
  • A constituent-specific modern dermal-limit standard for generic carvone was not verified in this pass.
  • 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.
