Hinoki root essential oil (Chamaecyparis obtusa var. obtusa, Cupressaceae roots steam distillate; same species as hinoki-leaf EO741 (21a previous batch — eudesmol+elemol foliage) and hinoki-wood EO743 (21b this batch — α-cadinol+T-muurolol heartwood) but distinct longipinene-skeleton root chemotype) is a longi-α-nojigiku alcohol + α-terpinyl acetate + longi-β-camphenilan aldehyde + cadinol cluster complex sesquiterpene-rich Cupressaceae-root oil with clean Tisserand & Young profile ("Hazards: None known. Contraindications: None known."). B216 Ch.13 p.616–617 cites Shieh et al 1981 chemistry: longi-α-nojigiku alcohol 19.7% + α-terpinyl acetate 9.1% + longi-β-camphenilan aldehyde 8.4% + T-cadinol 5.9% + α-cadinol 5.3% + cadin-1(10)-en-4,β-ol 5.0% + longicyclenyl alcohol 4.8% + T-muurolol 4.5% + δ-cadinene 3.8% + α-terpineol 3.5% + β-caryophyllene alcohol 2.6% + verbenone 2.4% + longiisohomocamphenilone 2.2% + γ-cadinene 2.1% + α-muurolene 1.7% + calamenene 1.6% + longiverbenol 1.3% + caryophylla-3,8(13)-dien-5,α-ol 1.3% + cadin-1(10)-en-4,α-ol 1.2%. Framework caps default conservative (no T&Y patch data: "No information found" for skin reactions + acute tox + carcinogenicity): adult dermal 5.0% + sensitive 3.0% + pregnancy 5.0% + pediatric cascade + max_oral 700 mg/day. Phototoxicity-NEGATIVE (Cupressaceae root, no furocoumarins). α-Cadinol active against human colon cancer cell line HT-29 (He et al 1997a). Same-species cross-part chemotype divergence rail (CRITICAL — fulfilled forward reference): hinoki-root (THIS oil — longipinene-skeleton root chemistry) ≠ hinoki-leaf (EO741 21a — eudesmane+ester foliage chemistry) ≠ hinoki-wood (EO743 21b same batch — α-cadinol+T-muurolol cadinane heartwood chemistry); same species, three plant parts, three radically different chemotypes. Longipinene-skeleton class singleton in Phase 3 mass-ingest — first oil with longi-α-nojigiku alcohol + longi-β-camphenilan aldehyde + longicyclenyl alcohol + longiisohomocamphenilone + longiverbenol longipinene-rearrangement-skeleton chemistry, distinct from cadinane (hinoki-wood) + eudesmane (hinoki-leaf) classes. Forms same-species triad with hinoki-wood EO743 (THIS batch) completing the Chamaecyparis obtusa leaf/root/wood triad opened by hinoki-leaf EO741 in 21a. Limited commercial availability — root extraction is niche; CITES var. formosana threatened-species rail also applies.

Cool damp earth cradling ancient roots, dry-warm cedar hush, softly balsamic with long-fading depth, faint camphor whispering from deep bark, settling stillness of forest dusk
Đất rừng mát ẩm ôm ấp rễ cổ thụ, gỗ khô-ấm thì thầm tuyết tùng, ngọt nhựa nhẹ với chiều sâu lắng đọng mãi, thoảng long não từ vỏ cây sâu thẳm, tĩnh lặng định thần tựa chiều rừng

Pha Chế & Hòa Hợp
Longi-α-nojigiku alcohol and the longipinene-skeleton sesquiterpene-alcohol fraction are linked to calming, centering olfactory character; inhalation pathway is presumed to modulate limbic activity, consistent with Cupressaceae root-oil class empirical use.
Ref: Tisserand & Young 2014, Ch.13 p.616–617 (hinoki root monograph)
Sesquiterpene alcohols (longi-α-nojigiku alcohol primary; cadinol secondary) are hypothesised to disrupt microbial membrane integrity; Cupressaceae EOs demonstrate broad-spectrum antimicrobial activity across leaf, wood, and root parts as a class.
Ref: class-extrapolation from hinoki-wood (Cupressaceae, cadinane-dominant, same species, Tisserand & Young 2014 Ch.13)
Cadinane-class sesquiterpene alcohols (secondary fraction) are associated with inhibition of pro-inflammatory mediator release; the longipinene-skeleton alcohol also suggests analogous membrane-modulatory behaviour at sites of inflammation.
Ref: class-extrapolation from hinoki-wood; Tisserand & Young 2014, Ch.13 p.616–617
Secondary α-cadinol (cadinane constituent present in hinoki root oil) showed selective cytotoxicity toward HT-29 colon carcinoma cells in vitro in *Taiwania cryptomerioides*; mechanism involves apoptosis induction extrapolated to hinoki root secondary cadinane fraction.
Ref: He et al. 1997a (Taiwania α-cadinol HT-29 in vitro — class-extrapolation to hinoki root secondary cadinane fraction)
Lipophilic sesquiterpene alcohols (longi-α-nojigiku alcohol and cadinol class) integrate into the stratum corneum lipid matrix, supporting barrier integrity; the monoterpene ester fraction contributes mild spasmolytic and barrier-smoothing properties.
Ref: Tisserand & Young 2014, Ch.13 p.616–617; class-extrapolation from Cupressaceae sesquiterpene-alcohol class
AI-summary
Traditional aromatherapy use; no RCT-grade clinical evidence located. Tisserand & Young (2014) provide the primary monograph reference (Ch.13 p.616–617) documenting constituents and safety framing for hinoki root oil. The sole cited controlled study is He et al. (1997a), which demonstrated α-cadinol from *Taiwania cryptomerioides* to be selectively cytotoxic toward HT-29 colon cancer cells in vitro; this is a class-extrapolation to hinoki root's secondary cadinane fraction only — no direct in vivo or human data exists for *Chamaecyparis obtusa* root oil. The primary constituent longi-α-nojigiku alcohol (a longipinene-rearrangement sesquiterpene alcohol singleton) has no independent pharmacological or clinical study record. Therapeutic claims rest on Cupressaceae class-level extrapolation and traditional Japanese Hinoki cultural use context.
