Pha Chế & Hòa Hợp
Carvacrol (15.4%) disrupts bacterial membrane integrity via phenol-class hydroxyl intercalation; geraniol (39.2%) potentiates as co-mechanism against Gram-positive and Gram-negative species.
Ref: B216 Ch.14 carvacrol + geraniol profiles (Tisserand & Young 2014); class-extrapolation
Geraniol (39.2%) disrupts fungal cell-membrane ergosterol integrity; carvacrol (15.4%) provides synergistic membrane-permeabilisation at phenol-class concentrations.
Ref: class-extrapolation from B216 Ch.14 geraniol + carvacrol profiles (Tisserand & Young 2014)
Geraniol (39.2%) suppresses NF-κB and pro-inflammatory cytokines; citral (16.3% geranial + neral combined) provides complementary prostaglandin-pathway modulation.
Ref: class-extrapolation from B216 Ch.14 geraniol profile (Tisserand & Young 2014)
Geraniol (39.2%) interferes with olfactory receptors of mosquitoes, ticks, and mites; citral (16.3%) adds repellent effect class-shared with lemongrass and may-chang.
Ref: class-extrapolation from B216 Ch.14 geraniol profile; class-extrapolation from may-chang (Tisserand & Young 2014)
Geraniol + citral lemon-fragrance class share proposed GABAergic calming effects with linalool-alcohol class; not confirmed in RCTs for this specific chemotype.
Ref: class-extrapolation from B216 Ch.14 citral + geraniol profiles (Tisserand & Young 2014)
Geraniol (39.2%) induces glutathione S-transferase (GST) in murine tissue via Phase II detoxification class; research context only, not a therapeutic claim.

AI-summary
No RCT-grade clinical evidence for Thymus × citriodorus as a whole oil in cited sources. Chemistry: Horváth et al (2006) per B216 p.859. Constituent-level: B216 Ch.14 documents carvacrol phenol-class antimicrobial, geraniol insect-repellent + anticarcinogenic GST-induction, and citral teratogenicity via retinoic acid synthesis inhibition. Citral (16.3%) drives a 3.7% adult dermal cap (T&Y via IFRA 2009 0.6% body-oils cap). CYP2B6 inhibition is a mechanistic concern from geraniol + citral (B216 Table 4.11B + Appendix B).

| Phương pháp | Liều lượng | Ghi chú |
|---|---|---|
| Diffusion / Ambient inhalation | 2–4 drops in 100 ml diffuser water; 1–2 drops on tissue | 30-min sessions. Avoid prolonged use with pregnant persons or patients on CYP2B6 substrates. Lemon-herbal top-note disperses quickly. |
| Topical massage | 1–2% in carrier oil (adult max 3.7% whole-oil per T&Y via IFRA citral cap) | Patch-test first. Avoid broken/sensitised skin. Contraindicated in pregnancy. Avoid with CYP2B6-substrate medications (B216 Appendix B). |
| Skincare (face and body) | 0.5–1% in serum or lotion; ≤0.5% facial | Geraniol provides toning + antimicrobial benefit. Avoid sensitive/reactive skin. Not phototoxic per B216. Not for use in pregnancy. |
| Warm compress | 2–3 drops pre-diluted in 10 ml carrier, applied to cloth | For localised antimicrobial or muscle use. Pre-dilute in carrier first. Limit to 10–15 min. Contraindicated in pregnancy. |
| Bath | 3–5 drops pre-dispersed in 15 ml carrier oil or full-fat milk | Must pre-emulsify — direct skin contact with undiluted citral raises sensitisation risk. Avoid in pregnancy and for children under 2. |
