- Lavandin is NOT lavender. Species hybrid with distinct safety profile from true lavender EO.
- Grosso is the lavandin cultivar with measured antiplatelet activity (Ballabeni 2004 IC₅₀ arachidonic acid / U46619 / collagen / ADP = 51 / 84 / 191 / 640 µg/mL). This is the empirical basis for T&Y's anticoagulant caution across all three cultivars.
- Oral cautions: anticoagulant medication, major surgery, peptic ulcer, hemophilia, other bleeding disorders (B216 p.655 + Box 7.1).
- Non-phototoxic, low sensitization at conventional dermal dilutions.
- Highest EO yield of the three cultivars → the cultivar most likely found in a generic "lavandin oil" supply. When a recipe calls for "lavandin" unqualified, it is most often Grosso.

Pha Chế & Hòa Hợp
Anxiolytic / sedative (mild)
Linalool (~25–38%) modulates GABA-A receptor activity and serotonergic signalling; linalyl acetate (~25–35%) deepens sedative quality. Higher camphor (6–9%) vs. L. angustifolia creates a calming-yet-toning profile rather than purely sedative.
Ref: Tisserand & Young 2014, B216 Ch.13 p.655–656; class-extrapolation from Lavandula angustifolia
Antiplatelet / anticoagulant
Grosso oil inhibits ADP- and collagen-induced platelet aggregation in vitro at measurable IC₅₀ values; the combined linalool + linalyl acetate + camphor constituent pool is the identified active fraction responsible for this Grosso-specific anticoagulant effect.
Ref: Ballabeni et al 2004 (Grosso-specific IC₅₀ data); Tisserand & Young 2014, Box 7.1 + Table 4.10B
Antispasmodic / muscle-relaxant
Linalyl acetate relaxes smooth muscle via calcium channel modulation; camphor (6–9%) adds counter-irritant analgesic activity at skeletal muscle, making Grosso more effective for muscular applications than true lavender at equivalent concentrations.
Ref: class-extrapolation from Lavandula angustifolia; Tisserand & Young 2014, B216 Ch.13 p.655–656
Anti-inflammatory (topical)
Linalool suppresses NF-κB-mediated pro-inflammatory cytokine release and inhibits cyclooxygenase activity; topical application delivers these effects to superficial skin and subcutaneous tissue (constituent-class evidence from L. angustifolia; Grosso-specific data absent).
Ref: class-extrapolation from Lavandula angustifolia (linalool constituent class)
Analgesic / counter-irritant
Camphor (6–9%) activates TRPV1 thermoreceptors, creating transient warming/cooling sensations that attenuate pain perception; increased local blood flow at the application site contributes an additional counter-irritant analgesic effect.
Ref: Tisserand & Young 2014, B216 Ch.13 (camphor constituent class)
Decongestant / mucolytic
1,8-Cineole (6–8%) stimulates mucociliary clearance and reduces secretion viscosity in upper respiratory mucosa; camphor adds mild topical bronchial counter-irritant effect when applied to chest or delivered via steam inhalation.
Ref: class-extrapolation from rosemary (Rosmarinus officinalis, 1,8-cineole class); Tisserand & Young 2014, B216 Ch.13
Antimicrobial (broad-spectrum, surface)
Linalool disrupts bacterial cell membrane integrity; 1,8-cineole and camphor contribute additional antibacterial activity; the combination is active against common Gram-positive skin pathogens at sub-irritant concentrations.
Ref: class-extrapolation from Lavandula angustifolia; Tisserand & Young 2014, B216 Ch.13
Skin-soothing / vulnerary
Linalool and linalyl acetate constituent class promotes keratinocyte proliferation and attenuates inflammatory cytokines at wound margins; camphor adds mild antiseptic activity (class-evidence from L. angustifolia; Grosso wound-specific data absent).
Ref: class-extrapolation from Lavandula angustifolia (linalool + linalyl acetate constituent class)
AI-summary
Grosso-specific controlled evidence is limited to one in vitro study: Ballabeni et al (2004) demonstrated lavandin Grosso inhibits ADP- and collagen-induced platelet aggregation with measurable IC₅₀ values — the primary source for T&Y Box 7.1 anticoagulant caution. No published RCT exists for Grosso's anxiolytic, analgesic, or sedative claims. The broader lavender clinical literature (predominantly L. angustifolia — Silexan oral preparations) cannot be directly extrapolated to Grosso given materially higher camphor (6–9%) and 1,8-cineole content. HRIPT and LD₅₀ testing (Opdyke 1976) confirm non-phototoxicity and favourable acute toxicity but are not efficacy data. Sensitization cohort data (Rudzki 1976; Frosch 1995a) establishes a low sensitization signal. Overall: one in vitro mechanistic study (Ballabeni 2004) plus constituent-class extrapolation; no Grosso-specific RCT-grade evidence located.

| Phương pháp | Liều lượng | Ghi chú |
|---|---|---|
| Diffusion | 3–5 drops per 100 ml water; 4–6 drops in cold-air diffuser | 30-min session; daytime calming and mild decongestant use; avoid near infants under 2 (camphor); for purely sedative or bedtime use, pure L. angustifolia is preferred. |
| Topical massage | 1–2% in carrier oil (adult body); 0.5% for face or sensitive areas | Avoid near infant face; patch-test for sensitive skin; jojoba or sweet almond carrier recommended; suitable for muscular tension, sports recovery, and headache (temples at 0.5%). |
| Bath | 4–6 drops dispersed in 1 tsp carrier oil or unscented bath gel | Disperse in carrier before adding to bath water; do not exceed 6 drops; avoid sitz bath; not for children under 3; camphor may irritate mucous membranes at higher concentrations. |
| Steam inhalation | 2–3 drops in a bowl of hot (not boiling) water; inhale 5–10 min | Keep eyes closed throughout; effective for sinus congestion and fatigue; caution in asthma — camphor + cineole may provoke bronchospasm in susceptible individuals. |
| Warm compress | 3–5 drops in 500 ml warm water; soak cloth and apply to target area | Apply to sore muscles or lower back; replace compress every 10 min; keep away from mucous membranes and eyes; do not apply over broken or acutely inflamed skin. |
| Topical skincare blend | 0.5–1% in unscented lotion or cream | Suited to normal/oily/combination skin; mandatory patch-test for sensitive skin; avoid periorbital area and broken skin; reduce to 0.5% for reactive or sensitized skin types. |
Dầu nền phù hợp
Jojoba (liquid wax)Extremely stable wax ester (near-zero oxidation) pairs well with lavandin's linalool peroxide precaution; lightweight, non-comedogenic, neutral scent; suitable for all skin types.
Sweet almond oilMedium-weight oleic/linoleic balance supports slow-work muscle massage; mild scent complements lavandin's floral-camphoraceous profile; skin-softening for dry patches in blends.
Fractionated coconut oilOdourless and colourless with rapid absorption; ideal for sports-recovery and quick-absorb topical applications; high oxidative stability reduces rancidity risk in finished blends.
Calendula-infused oilAnti-inflammatory triterpenoids synergize with lavandin's linalool/linalyl acetate skin-soothing profile; appropriate for lower-concentration sensitive or reactive skin applications.
Hemp seed oilGamma-linolenic acid provides anti-inflammatory fatty acid synergy with linalool and linalyl acetate; well-suited to mature and combination skin types in topical therapeutic blends.
