- Pelargonium x asperum Ehrh. ex Willd. — Egyptian chemotype (1 trong 4 origin chemotypes). Shared safety block với Chinese/Moroccan/Reunion.
- Hazards: Drug interaction + Skin sensitization (low risk). Contraindications: None known dermal. Oral caution diabetes meds + CYP2B6.
- Egyptian profile (Benveniste & Azzo 1992a): citronellol 24.8–27.7% + geraniol 15.7–18.0% (HIGH) + linalool 0.5–8.6% + citronellyl formate 6.5–6.7% + isomenthone 5.7–6.1%.
- Max dermal 17.5% T&Y (SYMELab 5% cap per platform convention); non-phototoxic.
- Egyptian = high-volume commercial chemotype (2nd after Reunion/Bourbon); dominant trong retail "Geranium EO" ở Mỹ/EU; chemistry "greener-rosier" do geraniol 15.7–18% cao hơn Chinese.

Tinh dầu phong lữ Ai Cập (Geranium Egyptian chemotype)
Pha Chế & Hòa Hợp
Anxiolytic / nervine tonic
Linalool and geraniol constituents modulate GABAergic and monoaminergic neurotransmitter pathways, producing mild calming and anxiolytic effects upon inhalation.
Ref: Tisserand & Young 2014, Ch.13 p.600–602
Antimicrobial (broad-spectrum)
Citronellol and geraniol, dominant monoterpenol constituents of the Egyptian chemotype, disrupt microbial cell membrane integrity against Gram-positive bacteria and opportunistic fungi.
Ref: Benveniste & Azzo 1992a [via B216]; class-extrapolation from geranium-bourbon
Antifungal
Geraniol inhibits fungal ergosterol biosynthesis and disrupts hyphal morphogenesis, consistent with the broader monoterpenol-class antifungal mechanism established in vitro.
Ref: class-extrapolation from geranium-bourbon; Tisserand & Young 2014, Ch.13 p.600–602
Hypoglycemic (preliminary)
Geranium EO constituents may potentiate insulin secretion or enhance peripheral glucose uptake; mechanism not fully elucidated but documented in animal model studies.
Ref: Boukhris et al. 2012 [via B216]
Sebum-regulating (skin balancing)
Isomenthone and monoterpenol-class constituents are proposed to normalise sebaceous gland secretion, supporting traditional use for oily and combination skin.
Ref: Tisserand & Young 2014, Ch.13 p.600–602; Tucker & Debaggio 2000 p.433 [via B216]
Cicatrisant / skin-healing
Geranium EO is traditionally applied to minor wounds and scars; monoterpenol constituents are proposed to support fibroblast proliferation and epithelial regeneration.
Ref: Tisserand & Young 2014, Ch.13 p.600–602
AI-summary
Boukhris et al. (2012) demonstrated hypoglycemic activity of Pelargonium sp. EO in animal models — the most specific clinical-grade study cited; it does not constitute human RCT evidence. Opdyke (1974, 1975) RIFM studies on Réunion and Moroccan geranium variants supply benchmark safety data (NOAEL) applicable by class to the Egyptian chemotype, but are not therapeutic efficacy trials. Frosch et al. (1995a), Sugiura et al. (2000), Rudzki et al. (1976), and Larsen et al. (2001) document geranium-type EOs as clinically relevant contact sensitizers in fragrance-allergic cohorts. No RCT-grade evidence for anxiolytic, antimicrobial, skin-balancing, or cicatrisant claims was located; these represent traditional aromatherapy use supported by in vitro constituent pharmacology.

| Phương pháp | Liều lượng | Ghi chú |
|---|---|---|
| Diffusion | 3–5 drops in 100 ml water | Blend with bergamot or palmarosa for emotional balancing. Limit to 30–60 min per session; avoid continuous diffusion exceeding 1 hour to prevent airway irritation. |
| Topical massage | 1–2% in carrier oil (6–12 drops per 30 ml) | Max dermal 5.0%. Preferred carriers: jojoba or sweet almond. Patch-test required — geraniol and citronellol are documented sensitizers (Frosch 1995a). Avoid broken skin. |
| Skincare blend | 0.5–1% in facial carrier (2–3 drops per 10 ml) | Suited to oily and combination skin. Pair with jojoba or argan. Avoid eye contour. Monitor for sensitization with repeat leave-on use. |
| Aromatic bath | 4–6 drops in bath emulsifier | Must dilute in full-fat milk or bath emulsifier before adding to water; undiluted EO on water surface risks mucous membrane irritation. Use warm water only. |
| Direct inhalation | 1–2 drops on tissue or personal inhaler | Brief intermittent use for acute emotional stress. Not recommended for children under 2 years or individuals with confirmed fragrance allergy. |
| Compress | 3–5 drops in 1 L warm water, apply soaked cloth | Suitable for local lymphatic drainage or minor skin support. Refresh compress every 15–20 minutes; discontinue if redness develops. |
Dầu nền phù hợp
JojobaNon-comedogenic liquid wax mimicking skin sebum; ideal partner for geranium's sebum-regulating properties in oily and combination skin formulations.
Sweet AlmondLight, emollient, and broadly well-tolerated; provides excellent glide for full-body massage blends and suits normal-to-dry skin types.
ArganHigh oleic acid and tocopherol content complement geranium's cicatrisant and toning properties in mature-skin facial formulations.
Rosehip SeedRich in linoleic acid and retinoic acid precursors; synergises with geranium's skin-regenerating action for scar reduction and anti-aging blends.
Fractionated CoconutStable, odour-neutral, and highly spreadable; extends blend shelf life and suits lightweight formulations for sensitive or reactive skin.
