- Citrus hystrix DC (Rutaceae) — leaves steam-distilled. Common names kaffir lime / makrut lime / leech-lime / Mauritius papeda / swangi (Southeast Asian cuisine staple).
- Hazards: None known. Contraindications: None known. Clean T&Y profile.
- Dermal cap 5.0% (framework default). Non-phototoxic (Rutaceae LEAF steam distillate — zero furocoumarin pathway).
- Chemistry: citronellal 58.9–81.5% dominant + citronellyl acetate 0.9–5.1% + isopulegol 0.3–4.9% + sabinene 1.6–4.8% + linalool 2.9–4.7% (Lawrence p.122). Chemistry completely inverted from [[combava-fruit]] (fruit peel citronellal only 0.4–16.8% + β-pinene dominant 25.9–31.5% vs leaf β-pinene 0.2–1.5%).
- Key rails: Same-species cross-variant rail vs [[combava-fruit]] — DIFFERENT plant part = DIFFERENT chemistry + DIFFERENT olfactory profile + DIFFERENT culinary role; verify plant part on supplier CoA. Non-phototoxic leaf-steam-distillate rail. Citronellal-dominant-oil peer class rail (joins [[citronella-java]] + [[citronella-sri-lanka]] + [[lemongrass]] + [[melissa]] — shared citronellal/citral aldehyde-rich safety pattern).

Bright lemon-fresh, clean aldehydic sparkle, faint rosy undertow beneath citrus clarity, cool green leaf whisper, diffusive and airy
Chanh sáng tinh khôi, lấp lánh trong sạch như buổi sớm, dư hương hoa hồng khẽ thoảng bên dưới làn trong suốt, lá xanh mát lạnh thì thầm, lan tỏa nhẹ như gió sớm

Pha Chế & Hòa Hợp
Monoterpene hydrocarbons (principally sabinene and β-pinene) disrupt bacterial cell membranes and inhibit enzymatic activity across Gram-positive and Gram-negative organisms.
Ref: class-extrapolation from Citrus leaf oils (Rutaceae family); Tisserand & Young 2014, Ch.13 p.545
In-vitro cytotoxic activity against KB (human oral epidermoid carcinoma) and P388 (murine leukemia) cell lines attributed to the combined monoterpene and oxygenated constituent profile.
Ref: Manosroi et al (2005)
Citronellal and monoterpene constituents interfere with insect olfactory receptor binding and contact deterrence, masking host-seeking cues at sub-threshold concentrations.
Ref: class-extrapolation from citronella oil (citronellal class); Tisserand & Young 2014, Ch.13 p.545
Fresh citrus-herbal aroma modulates limbic-system olfactory pathways, consistent with psychophysiological responses documented across the broader Citrus leaf oil class.
Ref: class-extrapolation from citrus leaf oils (Rutaceae family)
Monoterpene-rich profile (sabinene, β-pinene) impairs fungal cell wall integrity and ergosterol biosynthesis, consistent with other Citrus leaf EOs in the Rutaceae family.
Ref: class-extrapolation from Citrus leaf oils (Rutaceae family)
Oxygenated monoterpenes and sabinene may suppress NF-κB pathway activation and prostaglandin synthesis at therapeutic topical application concentrations.

AI-summary
No RCT-grade clinical evidence specific to Combava leaf essential oil has been located. The strongest available data is an in-vitro chemopreventive study: Manosroi et al (2005) reported cytotoxic IC50 activity against KB (human oral epidermoid carcinoma) and P388 (murine leukemia) cell lines, suggesting antiproliferative potential attributable to the oil's constituent profile. Chemistry characterisation is documented in Lawrence (p.122). All remaining therapeutic ratings are extrapolated from the broader Citrus leaf oil class within Rutaceae. Traditional aromatherapy and ethnobotanical use in Southeast Asian practice (Thailand, Indonesia, Cambodia) is well-established, but controlled human trials are absent. Traditional aromatherapy use; no RCT-grade clinical evidence located beyond the single in-vitro study above.

| Phương pháp | Liều lượng | Ghi chú |
|---|---|---|
| Diffusion | 3–5 drops in 100 ml water | 30–60 minute sessions for mood uplift and ambient antimicrobial effect. Blends well with lemongrass or bergamot FCF. Ventilate room between sessions. |
| Topical massage | 1–2% in carrier oil (max 5% adult per T&Y) | Preferred carriers: jojoba or fractionated coconut. Avoid on hypersensitive or broken skin. Patch test recommended. Keep well below 5% adult dermal ceiling. |
| Direct inhalation | 1–2 drops on tissue or cupped palm | 5–10 minute sessions for quick mood lift or mental clarity. Not recommended for children under 10 or those with reactive airways without practitioner guidance. |
| Room spray | 15–20 drops per 100 ml distilled water + dispersant | Shake before use. Suitable as insect-deterrent spray; synergises with citronella or eucalyptus. Avoid spraying directly onto polished or lacquered surfaces. |
| Skincare blend | 0.5–1% in lightweight carrier | Best for oily or combination skin. Avoid on sensitive or very dry skin. Patch test 48 h before full application. Do not use undiluted. Max adult dermal 5% (T&Y). |
