Pha Chế & Hòa Hợp
α-Thujone (63.3%) disrupts microbial cell membranes; 1,8-cineole (6.5%) contributes synergistic bactericidal activity at the sub-lethal dilutions permitted by the 0.4% dermal cap.
Ref: class-extrapolation from Artemisia absinthium (wormwood); Tisserand & Young 2014, Ch.13
High α-thujone content (63.3%) acts as a potent volatile insect deterrent; thujone-rich Artemisia species are consistently documented for this activity across traditional and modern use.
Ref: class-extrapolation from Artemisia absinthium; Tisserand & Young 2014, Ch.13
α-Thujone (63.3%) is a traditional stimulant of uterine smooth muscle contractility across the Artemisia genus; all-routes pregnancy contraindication is absolute, making this a safety hazard not a clinical indication.
Ref: Margaria R. 1963; Tisserand & Young 2014, p.898
α-Thujone directly modulates GABA-A receptors as a non-competitive antagonist; this underpins the convulsant and neurotoxic profile at supra-threshold doses and does not confer a safe anxiolytic benefit at the 0.4% dermal cap.
Ref: Höld KM, Sirisoma NS, Ikeda T et al. 2000 (PNAS 97(8):3826–3831)
Traditional Artemisia genus use for digestive spasm relief attributed to thujone-class monoterpene ketones acting on smooth muscle; the 0.4% cap severely restricts any practical GI-targeting topical application.

AI-summary
No RCT-grade clinical evidence exists for Artemisia maritima essential oil in aromatherapy. Primary mechanistic evidence is in vitro: α-thujone (63.3%) was characterised as a GABA-A receptor antagonist in rat neuron preparations (Höld et al. 2000, PNAS 97(8):3826–3831). The EU Scientific Committee on Food reviewed thujone safety comprehensively (SCF 2003b), establishing regulatory limits for food use. Margaria (1963) established the convulsion NOAEL at 10 mg/kg (male) / 5 mg/kg (female) rats — the gender-differential underpins the pregnancy and female-population caution. Chemistry is confirmed for the EO (Mathela et al. 1994). CRITICAL: the historical anthelmintic reputation (Flores Cinae) was attributable to santonin — a non-volatile sesquiterpene-lactone (mol. wt. 246 Da) that does NOT transfer into the steam-distilled EO. This traditional claim does NOT apply to the essential oil.

| Diffusion | 1-2 drops in 100 ml water; max 15-minute sessions | Diffuse in large, well-ventilated room only. Never around pregnant women, infants, children, or seizure-disorder patients. Prolonged inhalation poses independent neurotoxic risk. Specialist use only. |
| Topical spot application | 0.4% maximum in carrier (2 drops per 25 ml carrier oil) | Apply to small areas only; avoid face, mucous membranes, and damaged skin. Adult use only — never near children. Avoid entirely during pregnancy and breastfeeding. Wash hands post-application. |
| Inhalation (cloth/tissue) | 1 drop on cloth; hold 20-30 cm from nose; 1-2 brief breaths only | Trained practitioners only. No extended inhalation. Contraindicated for pregnant/breastfeeding women, children, and those with neurological or seizure history. Repellent use only. |
