- Angelica glauca Edgew., Apiaceae. Source: root; steam distillation. "Himalayan Angelica / Chora / Gandrayan / Smooth Angelica / Bạch chỉ Himalaya". COMPLETELY DIFFERENT CHEMISTRY from [[angelica-root]] (European A. archangelica) — this is a phthalide-dominant CNS-active oil, NOT a furanocoumarin-phototoxic oil. Indian traditional herbal medicine heritage (Garhwal + Kumaon Himalayan regions).
- Chemistry (Mathela 1988; Kapahi 1991 — via B216): (Z)-3-Butylidene phthalide 11.3–20.5% + (Z)-Ligustilide 8.2–17.4% + β-Phellandrene 5.1–14.2% + α-Pinene 4.3–11.8% + (Z)-3-Butylidene-4,5-dihydrophthalide 3.1–9.5% + Myrcene 2.0–7.1% + Sabinene 1.2–5.8% + p-Cymene 0.8–4.2% + δ-3-Carene 0.5–3.5% + Senkyunolide 0.4–2.8%. Phthalide-dominant (combined phthalides ≈25–50%).
- Hazards: CNS depression at high doses; theoretical drug interactions (CNS-sedative synergy); possible emmenagogue (folk). Contraindications: Pregnancy (all trimesters, all routes — folk + phthalide); children <6y. Max dermal: No T&Y numeric cap — framework 2–3% (phthalide CNS signal). Max oral: Framework ~30 mg/day conservative.
- Phthalide-CNS-active rail (CRITICAL — distinct from A. archangelica): Butylidene phthalide + ligustilide are CNS-active sedative-anxiolytic phthalide lactones — same chemistry family as Angelica sinensis (Dong Quai — ligustilide is the signature Dong Quai active) + Ligusticum chuanxiong (Chuan Xiong). Mechanism: GABA-A modulation + calcium channel modulation + smooth muscle relaxation. Sedative-hypnotic additive with alcohol + benzodiazepines + opioids + other CNS depressants. Traditional use for anxiety, insomnia, dysmenorrhea — consistent with mechanism.
- Species-confusion with A. archangelica rail (CRITICAL): Both are called "Angelica root oil" commercially but they are radically different products — European archangelica is furanocoumarin-phototoxic + CYP3A4 inhibitor; Himalayan glauca is phthalide-CNS-sedative + possible emmenagogue. NEVER substitute one for the other. Furanocoumarin content in A. glauca is negligible; phthalide content in A. archangelica is negligible. If CoA shows phthalides dominant = glauca; if furanocoumarins dominant = archangelica; if BOTH shown, the oil is suspicious (possible blend / adulteration).

Pha Chế & Hòa Hợp
(Z)-ligustilide and related phthalides modulate GABAergic and serotonergic pathways, producing calming and mild sedative effects consistent with the Angelica phthalide class.
Ref: Pang et al. (ligustilide pharmacology, class-extrapolation from A. sinensis research line); B216 Ch.14 phthalide profile composite
Phthalide constituents including butylidenephthalide and (Z)-ligustilide relax smooth muscle via calcium-channel antagonism, reducing visceral and musculoskeletal spasm.
Ref: B216 Ch.14 phthalide profile (celery + lovage + angelica glauca + chuan xiong composite)
Traditional Ayurvedic application of Chora/Gandrali root for flatulence, gastric discomfort, and digestive atony is supported by the antispasmodic phthalide chemistry of the root EO.
Ref: Ayurvedic Pharmacopoeia of India, Chora/Gandrali monograph; Tisserand & Young 2014, Ch.13 p.441
(Z)-ligustilide exerts uterotonic activity via oxytocin-receptor sensitisation in uterine smooth muscle, constituting the pharmacological basis for the absolute pregnancy contraindication.
Ref: Pang et al. (ligustilide uterotonic mechanism, A. sinensis research line); Ayurvedic Pharmacopoeia of India (classical pregnancy CI for Chora)
Phthalide constituents attenuate pro-inflammatory mediators and modulate nociceptive signalling pathways; evidence extrapolated from celery seed and lovage root phthalide class peers.
Ref: class-extrapolation from lovage-root and celery-seed EO peers; B216 Ch.14 phthalide profile composite
Himalayan Ayurvedic tradition classifies Gandrayan root as a vata-balancing nervine tonic for fatigue and nervous exhaustion; no constituent-level mechanistic confirmation specific to A. glauca.

AI-summary
No RCT-grade clinical evidence is available specifically for Angelica glauca essential oil. GC composition is characterised by Mathela (1988) and Kapahi (1991), confirming the phthalide chemotype shared with the broader Angelica genus. The primary pharmacological evidence for the dominant phthalide constituent (Z)-ligustilide derives from the A. sinensis research line (Pang et al.), where anxiolytic, antispasmodic, and uterotonic actions have been demonstrated in vitro and in rodent models. The Ayurvedic Pharmacopoeia of India documents classical Chora/Gandrali use for digestive, nervine, and analgesic indications with a traditional-use evidence grade. All therapeutic efficacy claims are traditional-use or class-extrapolation grade (rating ≤ 3); no controlled human studies on A. glauca EO were located in available citations.
