Section 1 — Identification
- Danh pháp khoa học
- *Matricaria recutita* L. (syn. *Matricaria chamomilla* L.; *Chamomilla recutita* (L.) Rauschert)
- Họ thực vật
- Asteraceae (Compositae)
- Bộ phận dùng
- Flower heads (capitula) — dried, including aerial parts
- Phương pháp chiết xuất
- Steam distillation (standard); CO₂ supercritical extraction also used for higher chamazulene preserv
- Màu sắc
- Deep indigo to dark cobalt blue — characteristic color from chamazulene (formed during distillation from matricine precursor). Color fades to green/yellow-green upon oxidation or prolonged storage.
- Phân loại nốt hương
- Middle note
- Hương thơm
- Middle note; sweet, herbaceous, warm, intensely floral-apple, slightly fruity-smoky, medicinal undertone. Distinctly different from Roman Chamomile — heavier, earthier, more medicinal.
- Chemotype / Cultivar
- Multiple chemotypes recognized: α-bisabolol CT (most common, Europe); bisabolol oxide A CT; en-yn-dicycloether CT; chamazulene-rich CT (high-grade therapeutic). Cultivar "Zloty Lan" (Poland) and "Manzana" (Germany) are well-known high-bisabolol strains.

- Tình trạng tại Việt Nam
- ⭐⭐★★★ | Imported only; available from specialty aromatherapy suppliers in Hanoi/HCMC (e.g., Aroma Life VN, Tinh dầu nhập khẩu); price range 300,000–800,000 VNĐ/5ml depending on grade and origin; often adulterated with Roman chamomile or diluted in carrier oil — source verification critical.

Section 2 — Chemical Composition (GC/MS)
| Cấu tử | Nhóm | % | Tác dụng |
|---|---|---|---|
| α-Bisabolol oxide A ★★★ DOMINANT | Sesquiterpenol oxide | 17–39% | Anti-inflammatory, skin-soothing, antimicrobial |
| α-Bisabolol | Sesquiterpenol | 5–14% | Anti-inflammatory, wound healing, skin penetration enhancer |
| Bisabolol oxide B | Sesquiterpenol oxide | 5–10% | Anti-inflammatory, antiseptic |
| Bisabolone oxide A | Sesquiterpene ketone oxide | 6–14% | Anti-inflammatory, antispasmodic |
| Chamazulene | Sesquiterpene (azulene) | 5–25% | Potent anti-inflammatory (COX-2 inhibitor), deep blue pigment |
| (E)-β-Farnesene | Sesquiterpene | 4–13% | Anti-inflammatory, mild insecticidal |
| En-yn-dicycloether (spiro ether) | Polyacetylene oxide | 6–22% | Antispasmodic, anti-inflammatory |
| Germacrene D | Sesquiterpene | 1–5% | Antimicrobial, insect repellent |
| 1,8-Cineole | Oxide (monoterpene) | 1–4% | Expectorant, anti-inflammatory |
| α-Terpineol | Monoterpenol | 1–3% | Antimicrobial, mild sedative |
- Chamazulene content is the primary quality marker and color indicator; high-grade therapeutic oil: ≥10% chamazulene - α-Bisabolol + bisabolol oxides = skin-active fraction; sum typically 30–60% of total oil - CO₂ extraction yields higher chamazulene (up to 35%) vs. steam distillation (5–20%) due to matricine conversion optimization - Chemotype significantly affects ratio: Egyptian oil tends to be chamazulene-dominant; German/Polish oil tends to be bisabolol-dominant ---

Section 4 — Therapeutic Properties
Chamazulene inhibits COX-2 and 5-LOX enzymes, blocking prostaglandin and leukotriene synthesis; α-bisabolol modulates NF-κB and MAPK pathways, reducing TNF-α, IL-6, and IL-17; demonstrated in both in vitro and in vivo models; Ref: PMC8515037 (2021); PMC9611340 (2022)
German chamomile volatile oil suppresses CD4+ → Th2/Th17 differentiation and reduces serum IgE, IgG1, and histamine in atopic dermatitis models; scratching frequency significantly reduced; Ref: PMC2833428 (2010 BALB/c murine model); PMID 29193940
En-yn-dicycloether and bisabolol exert smooth muscle relaxation; historically used for GI cramps; Ref: JAPS review 2013
Effective against periodontal pathogens (P. gingivalis, P. intermedia) comparable to 0.12% chlorhexidine at 50–75% oil concentration; Ref: PMID 38193176 (2023)
Apigenin (flavonoid co-constituent) binds benzodiazepine receptors; essential oil inhalation shows calming EEG effects; Ref: PMC2995283 (2010 review)
α-Bisabolol promotes fibroblast migration and collagen synthesis; accelerates mucosal repair; Ref: PMC6020515 (oral mucositis review, 2018)
Tâm Lý & Năng Lượng
Section 5 — Emotional & Energetic Profile
Tâm trạng: Deeply calming, grounding, emotionally balancing; reduces irritability and agitation
Chakra: Solar Plexus Chakra (Manipura) — releasing control/anger; Throat Chakra (Vishuddha) — authentic expression; Heart Chakra (Anahata) — grief and compassion
Ngũ hành: Kim (Metal — grief, skin, lung, releasing) + Mộc (Wood — liver, anger, emotional flow)
Cách Dùng & Pha Chế
Section 6 — Application & Formulation
Phù Hợp Loại Da
Section 7 — Skin Type Suitability
Antibacterial + anti-inflammatory reduces cystic acne inflammation; use at ≤1% to avoid pore congestion; jojoba carrier
Excellent; bisabolol enhances barrier function and moisture retention; combine with borage or rosehip
Balance sebum + soothe dry patches; use zone-specifically at 1–1.5%
One of aromatherapy's top choices for reactive skin; reduces redness, TEWL, and reactivity; patch test first for Asteraceae allergy
Reduces chronic micro-inflammation ("inflammaging"); bisabolol stimulates collagen synthesis; chamazulene = antioxidant
Indirect benefit via anti-inflammatory (post-inflammatory hyperpigmentation prevention); not a primary depigmenting agent
Top-tier evidence: reduces IgE, histamine, scratching; inhibits Th2/Th17 axis; use at 1% in borage/EPO carrier; Ref PMC2833428
Can reduce scalp inflammation/seborrheic dermatitis; 0.5–1% in argan or jojoba scalp serum; blue color may temporarily tint light hair

Giới hạn độ tuổi
- **Children under 2 years:** AVOID — sensitization risk; 1,8-cineole content (≤4%) is low but airway proximity caution for infants
Tương tác thuốc
- ! Warfarin / Anticoagulants:: α-Bisabolol and chamomile constituents may potentiate anticoagulant effects; monitor INR in patients on warfarin (Tisserand & Young caution; thebadgea
- ! Benzodiazepines / CNS depressants:: Additive sedative effects possible via apigenin-benzodiazepine receptor binding (primarily relevant to oral chamomile, but high-dose inhalation/topica
- ! CYP450 substrates:: Theoretical CYP1A2 and CYP3A4 modulation reported for chamomile extracts at high concentrations; clinical significance at typical aromatherapy doses u
Chống chỉ định
- x Known Asteraceae/Compositae family allergy (absolute contraindication — risk of contact sensitization or systemic allergic response)
- x Near eyes or mucous membranes undiluted
- x Internal use without qualified medical/aromatherapy practitioner supervision
- x Prolonged high-concentration use (>5%) on large body surface areas
Kiểm tra chất lượng
- **Genuine:** Deep indigo-blue to cobalt blue color (chamazulene); aromatic: intensely sweet-herbal-apple; GC/MS: α-bisabolol oxide A dominant + chamazulene ≥5%; optical rotation and specific gravity consistent with botanical source - **Adulteration risks:** - Addition of synthetic azulene (guaiazulene from guaiacwood) to mimic blue color — check via GC/MS for false chamazulene:bisabolol ratio - Dilution in carrier oil (check viscosity, specific gravity) - Substitution with Roman chamomi
Bảo quản
Amber glass, cool (8–15°C), away from light and oxygen; shelf life 2–3 years unopened; 12–18 months once opened. Blue color fades to green/brown upon oxidation — discard oxidized oil; use antioxidant (0.1% vitamin E / tocopherol) to extend stability ---

Section 9 — VN Context
Vùng trồng / sản xuất tại VN
** Chamomile flower cultivation reported in northern highland regions (Sa Pa/Lào Cai, Mộc Châu/Sơn La) with cooler climates suitable for the plant; primarily tea-grade, not EO-grade
Tên gọi tại Việt Nam
Trong Y học cổ truyền VN
- Not classified in classical YHCT (Y học cổ truyền); introduced via French colonial-era herbal medicine influence - Modern use in VN: trà hoa cúc (chamomile tea) for relaxation, mild insomnia, digestive comfort — predominantly flower infusion not essential oil - Topical: Urban VN aromatherapy community uses German chamomile EO for sensitive skin, eczema care, baby skincare products (imported)
Mua hàng tại VN
- Imported from Egypt, Germany, Hungary via wholesale channels; major VN EO distributors (Hanoi, HCMC) carry 5ml–30ml units - Price range: 300,000–800,000 VNĐ/5ml for genuine therapeutic grade; cheaper products (under 200k/5ml) are likely diluted or adulterated - Verify with GC/MS certificate; deep blue color is basic authenticity indicator - Avoid products labeled "Roman chamomile" if blue color and German/bisabolol chemistry is required
