Olfactory stimulation by the ester-rich, linalool-containing absolute activates limbic pathways associated with autonomic down-regulation; evidence class-extrapolated from steam-distilled EO grades with controlled inhalation studies showing reduced self-reported anxiety.
Ref: Tisserand & Young 2014, Ch.13 p.902–903; class-extrapolation from ylang ylang EO (steam-distilled grades)
An thần
Linalool and benzyl acetate, dominant constituents of the absolute, are associated with CNS depressant activity via GABA-A receptor modulation and reduction of sympathetic arousal at inhalation-relevant exposure levels.
Ref: Tisserand & Young 2014, Ch.13 p.902–903; class-extrapolation from ylang ylang EO
antidepressant / euphoric
The intensely narcotic, floral volatile profile (benzyl acetate, geranyl acetate, linalool) produces rapid mood-lifting and euphoric subjective effects via olfactory-limbic engagement; widely accepted in clinical aromatherapy practice.
Ref: Tisserand & Young 2014, Ch.13 p.902–903; Opdyke 1974 p.1015–1016
hypotensive
Inhalation of ylang ylang is associated with decreased systolic blood pressure and heart rate, attributed to parasympathetic enhancement and reduced peripheral vascular resistance; class-extrapolated to the absolute from EO-grade controlled studies.
Ref: Tisserand & Young 2014, Ch.13 p.902–903; class-extrapolation from ylang ylang EO
Tăng ham muốn
Traditional attribution: the narcotic-floral olfactory character and autonomic relaxant properties are empirically linked to enhanced libido and sensual mood; no RCT-grade evidence located in available citations.
Ref: Tisserand & Young 2014, Ch.13 p.902–903; traditional use
AI-summary
No RCT-grade clinical evidence specific to ylang ylang absolute (solvent-extracted) was located in the available §13 citations. Tisserand & Young (2014, Ch.13 p.902–903) address the absolute primarily in a safety context — isoeugenol sensitization risk, potential safrole content, and the IFRA 0.8% dermal cap — rather than efficacy endpoints. Opdyke (1974) monographs cover safety and toxicological parameters; Buccellato (1982) characterizes the absolute as a perfumery material without therapeutic endpoints. Clinical evidence for anxiolytic and hypotensive effects exists for steam-distilled ylang ylang EO grades (extra/complete/I–III) and is class-extrapolated to the absolute with caution, given that constituent ratios — particularly isoeugenol and safrole — differ materially between solvent extraction and steam distillation. Traditional aromatherapy use as an anxiolytic, euphoric, and hypotensive agent is widely accepted.

Phương pháp
Liều lượng
Ghi chú
Diffusion
1-2 drops in 100ml water; 20-30 min sessions only
Intensely narcotic floral scent; overdiffusion causes headache and nausea rapidly. Short intermittent sessions only. Dermal cap does not apply to inhalation route.
Topical massage
0.5–0.8% in carrier oil (HARD CAP: never exceed 0.8%)
Patch test mandatory — isoeugenol sensitizer (T&Y Ch.14). Use jojoba or fractionated coconut oil. Avoid broken/inflamed skin. Not for pregnancy or children without medical guidance.
Skincare (facial serum or cream)
0.3–0.5% in finished leave-on product
Stay below 0.8% IFRA cap for leave-on facial use. Suitable for dry or mature skin; contraindicated for sensitive/reactive skin (isoeugenol allergen risk, T&Y Ch.14).
Personal fragrance
Maximum 0.8% in leave-on fragrance product (IFRA 2009 cat 4–5 limit)
Heart note in fine fragrance; must not exceed 0.8% IFRA dermal limit. Blends with sandalwood, rose absolute, vetiver, bergamot. Patch test required before regular use.
Personal inhaler
2-3 drops on cotton wick in personal aromatherapy inhaler
Avoids dermal sensitization risk entirely. Limit to 5–10 slow inhalations per session; intense floral character causes olfactory fatigue if overused. Suitable for stress or pre-sleep use.
Dầu nền phù hợp
Jojoba oilOdour-neutral liquid wax; non-comedogenic, shelf-stable, ideal for precision dilution to the 0.5–0.8% hard cap without competing with the absolute's floral character.
Fractionated coconut oilLightweight and odourless; lets the absolute's scent predominate; excellent for massage where rapid absorption and a clean skin-feel are desired.
Sweet almond oilMildly emollient; traditional pairing for body and hair use in ylang-ylang-producing regions. Class-extrapolated from EO-grade Javanese hair-oil tradition.
Rosehip seed oilRich in linoleic acid with skin-regenerative properties; pairs well in mature or dry-skin serums at the low concentrations (0.3–0.5%) required for safe leave-on use.

Blend kinh điển
Bergamot FCF— Bergamot's bright citrus facets lift and temper ylang's narcotic weight, a classic pairing in chypre and tropical floral accords.
Sandalwood (East Indian)— The creamy-woody sandalwood anchors ylang's heady topnote, creating the backbone of classic Oriental compositions.
Patchouli— Patchouli's deep earthy-sweet character forms the hallmark ylang-patchouli Oriental accord, balancing narcotic brightness with grounded depth.
Rose Absolute— Shared rosy geraniol and geranyl acetate facets between the two absolutes build a luxuriant narcotic floral heart accord.

Tóm Tắt Khoa Học
Bản dịch Việt ngữ
Đây là Absolute (chiết bằng dung môi), không phải EO — quy trình hexane → rửa ethanol từ concrete. Thành phần hóa học khác biệt rõ so với 4 phân đoạn chưng cất hơi nước: ở đây có Safrole 0.4% (EO chưng cất chỉ có vết trong các phân đoạn đuôi); α-farnesene 14.9% + benzyl benzoate 11.8% + δ-cadinene 10.8% đều cao hơn phân đoạn tương đương.
IFRA 2009 giới hạn da 0.8% — áp dụng chung toàn nhóm (Safrole 0.4% gợi ý giới hạn 2.5% theo hồ sơ Safrole, nhưng thừa vì giới hạn Skin sensitization toàn nhóm 0.8% còn thấp hơn).
Safrole 0.4% = cờ cảnh báo thành phần — chất Carcinogenic ở loài gặm nhấm liều cao. T&Y (Tisserand & Young) ghi rõ: "hàm lượng safrole không đủ cao để gây lo ngại" ở mức giới hạn da 0.8%.
Không Phototoxic. Độc tính cấp toàn nhóm áp dụng ( > 5 g/kg).
α-Farnesene + δ-cadinene + benzyl salicylate cao hơn đáng kể → hồ sơ heart-to-base nặng hơn.
Linalool 13.2% ở mức trung bình giữa phân đoạn Extra và Complete.

§10 — da, cảm xúc, thể chất, hô hấp
Ứng dụng lâm sàng aromatherapy: Hạn chế — absolute thường dành cho perfumery. Nếu sử dụng trị liệu thì cho mục đích giảm lo âu (anxiolytic) / cân bằng cảm xúc, tương tự Complete nhưng giới hạn liều ≤0.5%.
Perfumery (ứng dụng chính): Neo hương heart-base trong nước hoa cao cấp (fine fragrance).
