- Aquilaria malaccensis Lam. (Thymelaeaceae). Also: Aquilaria sinensis (Lour.) Gilg. + A. crassna Pierre (unlisted here but a major Vietnamese-Cambodian source) + A. agallocha (now synonym of malaccensis). Source: fungus-infected heartwood only — healthy wood produces no agarwood. Steam distillation + CO₂ extracts. "Agarwood / Oud / Ood / Trầm hương / Kỳ nam / Aloeswood / Eaglewood / Lignum aloe".
- Fungal-infection heritage rail (CRITICAL): Agarwood oil is distilled ONLY from wood that has been infected by Phialophora parasitica or similar fungi. The infection stresses the tree into producing a dark, resinous, fragrant heartwood (agar) as a defense response. Healthy, uninfected Aquilaria produces no agarwood. Historically, natural infection was rare — hence the extreme price. Today, intentional inoculation is the industrial norm.
- Chemistry (Lawrence 1998e, Vietnamese sample): 2-(2-(4-Methoxyphenyl)ethyl) chromone 21.2–33.0% + 2-(2-Phenylethyl) chromone 16.1–23.6% + Oxo-agarospirol 1.4–5.3% + Guaia-1(10),11-dien-15-oic acid <4.7% + 6-Methoxy-2-(2-(4-methoxyphenyl)ethyl) chromone 2.0–3.7% + Guaia-1(10),11-dien-15-al 0.4–3.4% + Selina-3,11-dien-9-ol 0.4–2.8% + Selina-3,11-dien-9-one 0.2–2.1%. Chromone-dominant — a rare chemistry class, virtually unique to Aquilaria.
- Hazards: None known. Contraindications: None known. Acute toxicity: no information found. Carcinogenicity: no information found; no known carcinogens in the oil. Agarwood oil vapors are sedative to mice (Takemoto 2008) — supports traditional meditation + sleep-induction use.
- CITES Appendix II rail (CRITICAL sustainability): Aquilaria malaccensis is CITES Appendix II listed: "species that are not necessarily now threatened with extinction but that may become so unless trade is closely controlled." Legitimate trade requires CITES export permits. Cost: 10-15× jasmine absolute — one of the most expensive aromatic raw materials in the world. Strong economic incentive for adulteration; authentication is non-trivial without GC-MS.

Pha Chế & Hòa Hợp
sedative
Agarwood heartwood vapors reduced locomotor activity dose-dependently in mice, indicating CNS-depressant activity attributable to the complex sesquiterpene fraction of the heartwood EO.
Ref: Takemoto (2008) [via B216]
anxiolytic
Olfactory pathway activation by agarwood vapor is proposed to modulate limbic-system arousal, supporting emotional calming and meditative states; consistent with Takemoto (2008) sedative data and centuries of cross-cultural meditative use.
Ref: Takemoto (2008) [via B216]; Tisserand & Young 2014, Ch.13 p.434
skin-conditioning tonic (traditional)
Topical application of diluted agarwood EO is traditionally used in Ayurvedic and East Asian medicine as a skin tonic; no constituent-level mechanistic data available from provided citations.
Ref: Tisserand & Young 2014, Ch.13 p.434
anti-inflammatory
Sesquiterpene constituents characterising all three geographical chemotypes (Lawrence 1998e; Näf 1995; Bhuiyan 2009) share structural classes with anti-inflammatory sesquiterpenes in related heartwood oils; no direct agarwood-specific mechanistic study in provided citations.
Ref: class-extrapolation from sandalwood and guaiacwood sesquiterpene class; Lawrence (1998e) [via B216]
AI-summary
The sole controlled study in provided citations is Takemoto (2008), a murine sedative-vapor experiment showing dose-dependent locomotor reduction following agarwood inhalation — animal model only, not a human clinical trial. No RCT-grade evidence for any therapeutic action has been located in the citation set. Traditional use across Buddhist, Islamic, Ayurvedic, and Taoist medicine over several centuries provides a strong ethnobotanical signal for grounding, anxiety relief, and skin conditioning, but does not constitute clinical-grade evidence. Significant chemotype heterogeneity between Vietnamese (Lawrence 1998e), Indian (Näf 1995), and Bangladeshi (Bhuiyan 2009) sources complicates generalisable evidence assessment.

| Phương pháp | Liều lượng | Ghi chú |
|---|---|---|
| Diffusion | 2-4 drops in 100 ml water | Primary aromatherapy use. Suitable for meditation, evening wind-down (thiền định, thư giãn). Session 30–60 min in well-ventilated space. Pairs well with sandalwood or frankincense. |
| Topical massage | 1-2% in carrier oil (3-6 drops per 10 ml) | Well within the 5% adult max dermal limit. Apply to back, chest, or pulse points. Pair with jojoba or sweet almond. Avoid on broken or sensitised skin. |
| Skincare blend | 0.5-1% in carrier oil | Luxury face/neck tonic for mature or dry skin. Pair with rosehip or argan. Perform patch test before first use given significant chemotype variability between sources. |
| Direct inhalation | 1-2 drops on tissue or ceramic ring | Brief on-demand inhalation for acute grounding; 3-5 slow breaths. Avoid prolonged direct inhalation in confined spaces. Not suitable for children under 6. |
| Aromatic personal blend | 2-5% in jojoba oil | Pulse-point application (wrist, neck). Stays within adult max dermal 5%. Oud note is highly persistent; start at 2% and adjust. Verify sourcing origin before use. |
Dầu nền phù hợp
JojobaLiquid wax with near-indefinite shelf life complements the precious, costly nature of agarwood EO; non-comedogenic and suitable for both face and pulse-point applications.
Sweet AlmondLightweight oleic-rich profile supports massage applications; neutral aroma avoids competing with agarwood's distinctive woody-resinous oud note.
RosehipHigh linoleic/linolenic acids support mature and dry skin repair; synergistic pairing with agarwood's traditional skin-tonic use for anti-aging blends.
Fractionated CoconutFully saturated, odourless, long shelf life; ideal pre-dilution base for diffuser blends or meditation oils where no competing aroma is desired.
ArganLuxury positioning aligns with the premium status of agarwood; oleic acid and tocopherols support skin barrier function, reinforcing the traditional conditioning application.
