- Plectranthus barbatus Andrews (Lamiaceae) — root essential oil (unusual — most Lamiaceae EOs are leaf/flowering tops). Bornyl acetate 15% + β-sesquiphellandrene 13.2% + γ-eudesmol 12.5% sesquiterpene-rich profile.
- Hazards: None known. Contraindications: None known. Clean T&Y profile.
- Max dermal 5.0% framework default (no constituent-level restrictive cap triggered). Non-phototoxic Lamiaceae steam distillate.
- FORSKOLIN-NOT-IN-EO RAIL (CRITICAL): Forskolin — the Plectranthus barbatus active diterpene famous for cardiovascular + weight-loss + bronchodilator claims — resides in the root decoction / alcoholic extract, NOT in the steam-distilled essential oil. Consumer confusion hazard: "coleus forskohlii" supplements are typically standardized extracts, not EO.
- Sustainability rail: Wildgrown Indian populations threatened by medicinal collection (Misra et al 1994). Ethical sourcing relevant.

Pha Chế & Hòa Hợp
Antimicrobial (broad-spectrum)
Sabinsa CO₂ extract compositions (US Patent #6,607,712) demonstrate antimicrobial activity; bornyl acetate and sesquiterpene constituents contribute mild bacteriostatic effects.
Ref: US Patent #6,607,712 (Sabinsa Corporation); Tisserand & Young 2014, Ch.13 p.543
Antitumoral (in-vitro, constituent-level)
β-Sesquiphellandrene and γ-eudesmol — key sesquiterpene constituents — show antitumoral activity in cell-culture models; no EO-level animal or human clinical data available.
Ref: Chapter 14 Constituent profiles (β-Sesquiphellandrene + γ-Eudesmol antitumoral activity)
Mild analgesic / antispasmodic
Bornyl acetate, a prominent constituent, is associated with mild analgesic and antispasmodic effects well-documented across related Lamiaceae and Pinaceae bornyl acetate-class oils.
Ref: Opdyke (1973) p.1041–1042; class-extrapolation from inula and fir-needle bornyl acetate class
Grounding / calming (aromatic)
Root-derived sesquiterpene alcohols (γ-eudesmol) and earthy volatile profile support traditional aromatherapy use for grounding and nervous system calming.
Ref: Tisserand & Young 2014, Ch.13 p.543; traditional aromatherapy use
Mild anti-inflammatory
Bornyl acetate has mild COX-pathway inhibitory associations; γ-eudesmol belongs to the eudesmane sesquiterpene class with reported anti-inflammatory properties in related species.
Ref: Opdyke (1973) p.1041–1042; class-extrapolation from eucalyptus (γ-eudesmol-bearing oils)
AI-summary
No RCT-grade clinical evidence has been located for the steam-distilled Plectranthus barbatus essential oil. The extensive pharmacological research on coleus root (cardiovascular, glaucoma, weight-management) is attributed to forskolin — a non-volatile diterpene that does NOT distill over into the essential oil and therefore cannot be ascribed to EO use. Sabinsa Corporation's US Patent #6,607,712 documents antimicrobial compositions from CO₂ extraction but does not represent clinical trial data for the aromatherapy EO. Constituent-level in-vitro data (β-sesquiphellandrene + γ-eudesmol) suggest antitumoral potential, but no translation to human clinical outcome studies has been documented.

| Phương pháp | Liều lượng | Ghi chú |
|---|---|---|
| Diffusion | 3-5 drops in 100 ml water (ultrasonic diffuser) | Hương earthy-camphoraceous, phù hợp không gian thiền định hoặc thư giãn. Diffuse 30-40 min/session. Blend với vetiver hoặc frankincense để tăng hiệu quả grounding. |
| Topical massage | 1-3% in carrier oil (adult); 0.5% for sensitive individuals | Max dermal 5% adult per T&Y; dilute to 1% cho massage toàn thân. Thích hợp cho cơ bắp căng thẳng. Patch test khuyến cáo trước khi dùng diện rộng. |
| Inhalation (direct) | 1-2 drops on tissue or personal inhaler stick | Short-duration inhalation (1-2 min) for grounding or mood anchoring. Không dùng trực tiếp gần mũi trẻ nhỏ. Commercially rare oil — use sparingly. |
| Compress | 2-3 drops in 500 ml warm water | Apply warm compress to areas of muscle tension for 10-15 minutes. Dùng khăn flannel; tránh tiếp xúc vùng mắt và niêm mạc. |
Dầu nền phù hợp
Jojoba oilStable, non-comedogenic, long shelf-life pairs cleanly with the woody-earthy coleus profile; suits most skin types including oily-combination without clogging pores.
Fractionated coconut oilLight, odourless texture extends the earthy aroma without masking; good dermal penetration for topical muscle applications.
Sweet almond oilMild emollient with moderate absorption; well-suited for full-body grounding massage blends where sustained skin contact is intended.
