- Cabralea cangerana Saldanha (syn. Cabralea canjerana, Meliaceae) — wood steam-distillate. Brazilian / South American hardwood tree.
- Hazards: Potentially carcinogenic (T&Y) based on safrole 0.5% content. No other hazards flagged; contraindications: none known.
- Dermal caps — safrole-derived: EU 2.0% + IFRA 2.0% + T&Y max_dermal 10.0%. IFRA + EU drive cap via safrole 0.01% in cosmetics rule (dermal limit 0.05% + oral 0.025 mg/kg/day for safrole per Ch.14).
- Max oral 350 mg/day — T&Y safrole-derived.
- Chemistry (Weyerstahl 1996): sesquiterpene-dominant — β-caryophyllene 28.6% + germacrene D 9.3% + δ-cadinene 7.4% + germacrene B 6.2% + γ-muurolene 5.0% + α-calacorene 2.9% + γ-cadinene 2.7% + α-muurolene 2.4% + γ-elemene 2.4% + δ-elemene 2.3% + α-copaene 2.1% + caryolan-8-ol 1.8% + α-caryophyllene 1.8% + γ-amorphene 1.4% + β-elemene 1.3% + aromadendrene 1.1% + safrole 0.5%.

Pha Chế & Hòa Hợp
grounding / calming (inhalation)
Woody sesquiterpene volatiles activate limbic olfactory pathways associated with grounding and calming responses; consistent with the broad class of tropical wood EOs where sesquiterpene-hydrocarbon fractions are the primary aromatic drivers.
Ref: class-extrapolation from wood EOs (sandalwood, cedarwood); Tisserand & Young 2014 Ch.13 p.498–499
antimicrobial — broad-spectrum
Sesquiterpene and aromatic constituents characterised by Weyerstahl et al (1996) likely disrupt microbial membrane integrity via lipophilic intercalation, consistent with antimicrobial activity documented for Meliaceae family wood EOs.
Ref: class-extrapolation from Meliaceae wood oils; Weyerstahl et al 1996 (chemistry analysis)
anti-inflammatory (topical, local)
Sesquiterpene hydrocarbons in the Weyerstahl (1996) chemistry profile share structural features with β-caryophyllene-class sesquiterpenes that inhibit COX-2 and NF-κB inflammatory mediator pathways at dilute topical concentrations.
Ref: class-extrapolation from sesquiterpene-rich wood EOs; Weyerstahl et al 1996 (chemistry baseline)
topical antiseptic / preservative potential
Safrole-class phenylpropanoids documented by Weyerstahl et al (1996) confer antimicrobial activity via membrane disruption; the IFRA 0.01% finished-product cap reflects genotoxicity precaution, not absence of antiseptic utility at sub-threshold doses.
Ref: class-extrapolation from safrole-bearing EOs; Tisserand & Young 2014 Ch.14 (Safrole profile)
AI-summary
Traditional aromatherapy use only; no RCT-grade or controlled clinical evidence located for Cabralea cangerana essential oil. The sole peer-reviewed chemical reference is Weyerstahl et al (1996), which documents the volatile composition but reports no clinical endpoints. Tisserand & Young (2014) Ch.13 p.498–499 provides safety guidance with the 2.0% adult max dermal cap derived from the safrole constituent (IFRA cosmetic restriction ≤ 0.01% in finished product; EU Cosmetic Regulation safrole ban). Safrole is a documented genotoxin and potential carcinogen per Tisserand & Young Ch.14; this restricts clinical development compared to low-safrole wood EOs. All therapeutic action ratings are class extrapolations from chemically analogous Meliaceae wood EOs and the sesquiterpene pharmacology literature.

| Diffusion | 2–3 drops in 100ml water in electric diffuser | Limit session to 30–60 min; ventilate room between sessions. Contraindicated during pregnancy. Not suitable for children under 12. |
| Topical massage | Max 2% in carrier oil (≈ 6 drops per 10ml carrier, adult only) | Patch test required due to safrole content. Avoid broken or sensitive skin. Not for pregnant women, nursing mothers, or children under 12. |
| Warm compress | 1% in carrier oil applied to compress cloth | Apply warm compress for up to 20 min only. Dilute strictly within 2% adult dermal cap. Avoid in pregnancy and on sensitive skin. |
Dầu nền phù hợp
Jojoba waxChemically stable with long shelf life; neutral aroma does not compete with cangerana's woody character; precise dosing supports compliance with 2% adult dermal cap.
Sweet almond oilLight texture and good skin penetration suit this wood EO in massage; emollient action supports the 2% dilution for dry-to-normal skin types.
Fractionated coconut oilOdourless and non-greasy; facilitates accurate dilution calculations when formulating near the IFRA safrole-content limit in finished products.
