Linaloe wood essential oil (Bursera glabrifolia Humb. synonym B. delpechiana Poisson + 4 other Bursera species: B. aloexylon Schiede, B. fagaroides Humb., B. penicillata Sesse & Moc., B. simaruba L., Burseraceae family — same family as elemi/frankincense/myrrh genus relatives) is a linalyl-acetate + linalool DOMINANT 77% combined wood-distilled CLEAN ester-alcohol monoterpene EO with clean-T&Y "None known × 2" hazard signature. B216 Ch.13 p.677 cites Lawrence 1979 p.3 chemistry: linalyl acetate 47.0% (dominant) + linalool 30.0% (secondary) + α-terpineol 8.5% + geranyl acetate 3.5% + neryl acetate 2.5% + (Z)-linalool oxide 2.0% + methyl heptenol 1.5% + geraniol 1.0% + (E)-linalool oxide 1.0%. Hazard signature: T&Y verbatim "Hazards: None known. Contraindications: None known." Framework safety cap 5% per T&Y "None known × 2" baseline framework default. CRITICAL latent-linalool-oxidation-IFRA-rail (B216 EXPLICIT verbatim): "According to IFRA, essential oils rich in linalool should only be used when the level of peroxides is kept to the lowest practical value. The addition of antioxidants such as 0.1% BHT or α-tocopherol at the time of production is recommended (IFRA 2009)." Opdyke 1979a clean clinical data verbatim: "Undiluted linaloe wood oil was moderately irritating to rabbits, but was not irritating to mice or pigs; tested at 8% on 25 volunteers it was neither irritating nor sensitizing. It is non-phototoxic." Acute toxicity verbatim: "Linaloe wood acute oral LD50 in rats > 5 g/kg; acute dermal LD50 in rabbits > 5 g/kg." No carcinogen-class concern — B216 EXPLICIT "No information was found for linaloe wood oil, but it contains no known carcinogens." CRITICAL conservation-rail-Arctander-1960 (B216 EXPLICIT verbatim): "According to Arctander (1960) the essential oil can be considered partly a pathological product, since the oil content in undamaged trees is too low for economical exploitation. The felling of entire, old and damaged trees is less practical and less environmentally sound than harvesting the leaves or fruits for distillation." → Sustainability rail: prefer leaves/fruits-distilled linaloe over wood-distilled when available; wood EO depends on tree-felling of damaged old growth. CRITICAL 5-species Bursera umbrella rail: B216 explicitly enumerates B. glabrifolia (= B. delpechiana) PLUS B. aloexylon + B. fagaroides + B. penicillata + B. simaruba — 5-species commercial source umbrella. Latent linalool autoxidation hydroperoxide skin sensitization is class-shared with other linalool-rich EOs (rosewood Aniba rosaeodora + ho-wood + ho-leaf + lavender-true + lavandin + bergamot + petitgrain + coriander-seed + thyme-linalool-CT + basil-linalool-CT + clary-sage).

Pha Chế & Hòa Hợp
Linalool (30%) modulates GABA-A receptor activity and reduces limbic system arousal, producing dose-dependent calming effects documented across the linalool-dominant EO class.
Ref: class-extrapolation from lavender (linalool/linalyl acetate dominant class peer); Tisserand & Young 2014, Ch.13 p.677
Inhaled linalool vapor reduces locomotive activity and prolongs sleep duration in preclinical models via CNS interaction; effect magnitude reflects wood-distilled chemotype, lower linalool fraction than lavender.
Ref: class-extrapolation from ho-wood (Cinnamomum camphora linalool CT, linalool-dominant class peer)
Linalool disrupts Gram-positive bacterial membrane integrity; linalyl acetate (47%) may synergize through ester hydrolysis to acetic acid, lowering local pH at the membrane interface.
Ref: class-extrapolation from rosewood (Aniba rosaeodora, linalool-dominant class peer); Tisserand & Young 2014, Ch.13 p.677
Linalool interferes with fungal ergosterol biosynthesis and cell membrane fluidity at concentrations consistent with the linalool-class EO profile.
Ref: class-extrapolation from thyme linalool CT (linalool-dominant class peer)
Linalool downregulates NF-κB signaling and inhibits COX-1/COX-2 in in-vitro models; linalyl acetate contributes via ester-mediated reduction of pro-inflammatory eicosanoid synthesis.
Ref: class-extrapolation from lavender (linalool/linalyl acetate class); Tisserand & Young 2014, Ch.13 p.677
Linalyl acetate (47%) combined with linalool creates a floral-woody olfactory cue influencing limbic mood circuits; preclinical evidence for linalool-class serotonergic and dopaminergic interaction.
Ref: class-extrapolation from clary sage (linalyl acetate dominant, linalool class peer)
AI-summary
No RCT-grade clinical studies for Bursera glabrifolia EO were located in available citations. Opdyke (1979a) provides the primary safety dataset: acute oral LD50 >5 g/kg (rats), acute dermal LD50 >5 g/kg (rabbits), 8% undiluted moderately irritating to rabbits, but 8% in 25 human volunteers produced neither irritation nor sensitization; confirmed non-phototoxic. These findings address safety tolerability only — no therapeutic efficacy endpoints. All therapeutic attributions derive by class-extrapolation from better-studied linalool-dominant oils (lavender, rosewood, ho-wood). Tisserand & Young 2014 (Ch.13 p.677) list no specific clinical therapeutic studies for this oil.

| Phương pháp | Liều lượng | Ghi chú |
|---|---|---|
| Diffusion | 3–5 drops per 100 ml water | 30–60 min sessions. Blend with bergamot or petitgrain for citrus-lift. Best for calming or sleep-support contexts. |
| Topical massage | 1–2% in carrier oil (max 5% adult) | Dilute in jojoba or sweet almond. Antioxidant-rich carrier preferred to protect linalool pool against autoxidation during storage. |
| Personal inhalation | 2–3 drops on cloth or inhaler wick | Hold 5–10 cm from nostrils; 5–10 slow breaths. Replace cloth every 24 h to avoid exposure to oxidised linalool hydroperoxides. |
| Skincare blend | 0.5–1% in facial carrier | Keep ≤1% on facial skin. Pair with argan or rosehip — tocopherol-rich carriers double as antioxidant to inhibit linalool hydroperoxide formation. |
| Aromatic bath | 4–6 drops in 15 ml carrier, then added to bath | Always pre-disperse in carrier or bath gel before adding to water. No T&Y contraindication listed; apply standard caution for children under 3. |
