Pha Chế & Hòa Hợp
Nerolidol (20–30%), the dominant acyclic sesquiterpene alcohol, was isolated as the bioactive antiulcer fraction of B. dracunculifolia EO in a reverse-pharmacology mucosal-protection animal model.
Ref: Klopell, Lemos, Sousa et al 2007, Phytomedicine 14(7-8):507-514
(+)-Limonene (4.7–18%) and nerolidol both carry anticarcinogenic-class designations in Tisserand & Young Ch.14 via GST-induction and apoptosis-modulation pathways; evidence is preclinical only, not a therapeutic claim.
Ref: Tisserand & Young 2014, Ch.14 constituent profiles — nerolidol + (+)-limonene anticarcinogenic class; B216 p.880-881
Nerolidol, a farnesol-related acyclic sesquiterpene alcohol, disrupts microbial membrane integrity and biofilm formation; class-extrapolation from documented in vitro antimicrobial activity of sesquiterpene alcohol-rich Asteraceae EOs.
Ref: class-extrapolation from nerolidol constituent class (Tisserand & Young 2014, Ch.14)
Nerolidol's lipophilic low-volatility sesquiterpene structure supports CNS sedative-calming effects via slow inhalation delivery; class-extrapolated from peer sesquiterpene alcohol-dominant EOs sharing the nerolidol signature.
Ref: class-extrapolation from nerolidol constituent class; see siam-wood EO801 peer — Tisserand & Young 2014, Ch.14
Globulol (2.5–14.5%) and nerolidol in combination are associated with inhibition of pro-inflammatory mediators in sesquiterpene alcohol class studies; no vassoura-specific anti-inflammatory study was located in §13 citations.
Ref: class-extrapolation from sesquiterpene alcohol class (Tisserand & Young 2014, Ch.14); B216 p.880-881
Nerolidol carries an explicit 'extremely low skin sensitization potential' designation in T&Y Ch.14; B216 confirms the full vassoura profile as 'None known × 2' with all major constituents non-toxic, making it exceptionally well-tolerated.

AI-summary
No RCT-grade clinical evidence exists specifically for vassoura (Baccharis dracunculifolia) EO in human aromatherapy. The strongest direct evidence is Klopell et al 2007 (Phytomedicine 14:507-514), a reverse-pharmacology animal study isolating nerolidol from B. dracunculifolia EO as the bioactive antiulcer constituent conferring gastroprotective mucosal effects — this underpins the anti-ulcer rating but does not constitute clinical aromatherapy evidence. CRITICAL: Brazilian green propolis (derived from B. dracunculifolia resin) has 70+ peer-reviewed clinical studies, but propolis is a bee-processed resinous product with categorically different chemistry from the steam-distilled EO; those findings CANNOT be extrapolated to vassoura EO. B216 notes all major constituents (nerolidol, limonene, pinenes, globulol) as non-toxic and non-carcinogenic at standard dilutions (framework 5%).

| Phương pháp | Liều lượng | Ghi chú |
|---|---|---|
| Diffusion | 3–5 drops per 100ml water | Nerolidol low volatility (base note); diffuse 30–45 min for grounding atmosphere. No inhalation restrictions (B216 'None known × 2'). Workspace or evening use. |
| Topical massage | 1–3% in carrier oil (max adult framework 5%) | Nerolidol has extremely low sensitization potential. Prefer 1% for facial use. Pair with jojoba or sweet almond carrier. Avoid broken skin. |
| Skincare blend | 0.5–2% in facial serum or unscented lotion | Low sensitization nerolidol profile suits sensitive, reactive, or mature skin. Daily use within 5% adult framework cap. Pair with rosehip for mature skin. |
| Direct inhalation | 1–2 drops on tissue or cupped palms | 5–10 min inhalation for grounding and calming. Sesquiterpene base-note diffuses slowly. Safe for general adult use; no special population restrictions. |
| Bath blend | 4–6 drops in 1 tsp carrier or emulsifier before adding to bath | Dissolve in carrier or liquid soap before adding to bathwater (dispersion safety). Relaxing evening soak; no specific contraindications documented. |
