Intense sweet-medicinal-balsamic, characteristic "wintergreen tea" + "Bengay" + "root-beer" + "tooth-paste" vernacular character; warm-balsamic-rooty undertone; signature aromatic-ester profile dominating completely
Mạnh đặc trưng ngọt-thuốc-balsamic, mùi "trà wintergreen" + "thuốc xoa bóp" + "kẹo cao su" + "kem đánh răng" cổ điển; nốt ấm-balsamic-mộc-rễ; profile aromatic-ester signature thống trị hoàn toàn

Pha Chế & Hòa Hợp
Methyl salicylate (96–99.5%) inhibits COX-mediated prostaglandin synthesis and activates TRPV1/TRPA1 receptors producing counterirritant warmth; mechanism pharmacologically established but requires topical application, which is CONTRAINDICATED for all self-use.
Ref: Tisserand & Young 2014, Ch.14 — methyl salicylate constituent profile
Methyl salicylate hydrolyzed post-absorption to salicylic acid, contributing to anti-inflammatory prostaglandin inhibition; class-extrapolation from salicylate pharmacology — all dermal and oral routes are CONTRAINDICATED for self-use.
Ref: class-extrapolation from salicylate drug class; Tisserand & Young 2014, Ch.14
Methyl salicylate inhibits platelet aggregation via thromboxane A2 suppression and potentiates warfarin/heparin effects even via transdermal absorption; documented drug interaction hazard, not a therapeutic action.
Ref: Le Bourhis & Soenen 1973; Tanen et al 2008; Heng 1987
The intense medicinal-minty volatile signature of methyl salicylate provides strong olfactory stimulation when diffused at very low concentration; diffusion is the only safe consumer-accessible route for this oil.
Ref: Tisserand & Young 2014, Essential Oil Safety p.890-892
AI-summary
No aromatherapy RCT-grade clinical evidence located for wintergreen EO. The published literature overwhelmingly documents acute toxicity rather than therapeutic efficacy: Opdyke 1978 reports 50–60% mortality in poisoning cases; Davison et al 1961 documented 427 deaths in the USA (1926–1943); Stevenson 1937 recorded 41 historical cases with high pediatric fatality. Methyl salicylate at 96–99.5% means 1 mL ≈ 1,400 mg — equivalent to ~21 adult aspirin tablets. Transdermal absorption sufficient for systemic poisoning is documented (Heng 1987). JECFA 1967 ADI: 0.5 mg/kg/day (2-year dog study + UF-100). Health Canada cosmetic maximum: 1% topical. No controlled efficacy RCTs exist at safe aromatherapy dilutions.

| Phương pháp | Liều lượng | Ghi chú |
|---|---|---|
| Diffusion (ultrasonic/room diffuser) | 1–2 drops per 100 ml water; max 15-min intervals | Sole safe consumer route. Well-ventilated space only. Do NOT diffuse near children, pregnant women, or anticoagulant-medication users. Aroma is very intense — 1 drop usually sufficient. |
| Inhalation from tissue | 1 drop on tissue; brief inhalation, max 15 seconds | Brief aromatic appreciation only, not therapeutic. AVOID: children, pregnant/breastfeeding, salicylate sensitivity (incl. ADD/ADHD), anticoagulant users. No prolonged or repeated exposure. |
