- Cymbopogon giganteus (Hochst.) Chiov., Poaceae (Gramineae). Source: leaves; steam distillation. "Ahibero / Tsauri grass / Cỏ ahibero". Another less-common commercial Cymbopogon species (alongside [[african-bluegrass]] C. validus) — primarily West African origin (Burkina Faso, Benin, Nigeria, Ivory Coast). "Limited availability" per T&Y.
- Chemistry (Menut 2000 — via B216): (E)-p-Mentha-1(7),8-dien-2-ol 24.0–35.2% + cis-p-Mentha-1(7),8-dien-2-ol 17.9–28.4% + Limonene 1.3–8.8% + β-Caryophyllene 1.2–4.2% + Myrtenol 2.0–3.5% + trans-Carveol 1.4–2.6% + Terpinolene 0.1–2.3% + (E)-β-Ocimene tr–1.8% + α-Pinene 0.7–1.7% + β-Pinene 0.2–1.5% + Caryophyllene oxide 0.1–1.4% + Geraniol 0.2–1.2%. p-Mentha-dien-2-ol dominant (cis + trans combined ≈42–64%) — unique outlier chemistry, NOT citral / geraniol / citronellal / myrcene.
- Hazards: None known. Contraindications: None known. No dermal max stated by T&Y — low-risk profile; framework 3–5% adult general.
- Cymbopogon-outlier-chemistry rail: p-Mentha-1(7),8-dien-2-ol is a cyclic monoterpene alcohol with an exocyclic methylene — no published toxicology specific to this constituent. Falls under monoterpene alcohol default framework (OK up to 5% dermal in adults, similar to linalool / α-terpineol-dominant oils).
- Limited-availability + no-adulteration-listed rail: T&Y does not list adulteration cautions — consistent with West African niche supply + small commercial market. Closes out the Cymbopogon genus cluster alongside [[palmarosa]] (motia), lemongrass, citronella, gingergrass, [[african-bluegrass]] (validus).

Pha Chế & Hòa Hợp
antimicrobial (broad-spectrum)
Volatile terpene aldehydes and monoterpene hydrocarbons characteristic of steam-distilled Cymbopogon species disrupt microbial cell membranes; genus-level pattern documented across peer Cymbopogon oils.
Ref: class-extrapolation from Cymbopogon citratus (lemongrass); Tisserand & Young 2014, Ch.13 p.435
insect repellent
African Cymbopogon species share volatile monoterpene and sesquiterpene constituents that function as arthropod antifeedants and spatial repellents via olfactory receptor interference.
Ref: class-extrapolation from Cymbopogon nardus (citronella); Tisserand & Young 2014, Ch.13 p.435
anxiolytic / mood-lifting
Inhalation of Poaceae-family volatiles stimulates olfactory bulb projections to limbic structures; grass-class aromatic profiles are associated with mild mood modulation via hedonic olfactory pathways.
Ref: Tisserand & Young 2014, Ch.13 p.435
anti-inflammatory (mild, topical)
Monoterpene and sesquiterpene fractions in Cymbopogon steam-distillates suppress pro-inflammatory mediator release at concentrations achievable within the 5% topical dilution framework.
Ref: class-extrapolation from Cymbopogon citratus; Tisserand & Young 2014, Ch.13 p.435
AI-summary
Traditional aromatherapy use; no RCT-grade clinical evidence located specifically for Cymbopogon giganteus essential oil. Available literature is limited to GC compositional analysis (Menut 2000, via B216) and a brief safety profile in Tisserand & Young (2014, Ch.13 p.435). All therapeutic actions derive from class-level extrapolation across the Cymbopogon genus (lemongrass C. citratus, citronella C. nardus, palmarosa C. martinii). This species is considered under-researched relative to its commercial Cymbopogon peers. Practitioners should treat all efficacy claims as preliminary pending species-specific controlled studies.

| Phương pháp | Liều lượng | Ghi chú |
|---|---|---|
| Diffusion | 3-5 drops per 100ml water | Preferred route given limited dermal evidence. Run 30-60 min cycles; ventilate room between sessions. Useful for ambient insect deterrence and mood support. |
| Topical massage | 1-2% in carrier oil for first use; up to 5% adult maximum | Perform patch test 24h prior given sparse sensitization data. Dilute in jojoba or sweet almond. Not for children under 2 years. |
| Inhalation (direct) | 1-2 drops on tissue or inhaler stick | Brief 2-5 min exposures for acute mood or mental clarity support. Avoid prolonged direct inhalation at high concentration. |
| Bath | 5-8 drops pre-dispersed in bath salts or full-fat milk | Must pre-dilute in a dispersant before adding to water. Keep total EO ≤1% of bath volume to avoid undiluted skin contact. |
Dầu nền phù hợp
Jojoba oilLightweight, long shelf life, suitable for all skin types; does not overpower the grassy-herbaceous character of ahibero.
Sweet almond oilNeutral scent and gentle skin feel; ideal for massage blends where the ahibero note should remain prominent.
Fractionated coconut oilNon-greasy, good dermal penetration; practical first-use patch-test vehicle given limited dermal sensitization data on this species.
