Pha Chế & Hòa Hợp
Sesquiterpene hydrocarbons and alcohols (cadinane-class) from Cupressaceae wood engage olfactory limbic pathways, promoting psychological grounding, calm, and emotional stability.
Ref: class-extrapolation from cedarwood-atlas, cedarwood-virginian, cedarwood-himalayan (Cupressaceae wood sesquiterpene grounding class)
Cadinane sesquiterpene alcohols (α-cadinol class) from Cupressaceae wood oils disrupt microbial cell-membrane integrity, conferring broad-spectrum antimicrobial activity across the sesquiterpene-alcohol chemical class.
Ref: class-extrapolation from cedarwood-atlas, cedarwood-virginian, hinoki-wood (Cupressaceae sesquiterpene-alcohol antimicrobial class)
α-Cadinol and cadinene sesquiterpene alcohols disrupt fungal membrane ergosterol biosynthesis; antifungal activity is established for the cadinane sesquiterpene class across multiple Cupressaceae wood species.
Ref: class-extrapolation from cedarwood-atlas, cedarwood-virginian, hinoki-wood (cadinane sesquiterpene antifungal class)
Sesquiterpene hydrocarbons (δ-cadinene, bisabolene class) in Cupressaceae wood oils modulate prostaglandin synthesis pathways; anti-inflammatory activity inferred from constituent-class chemistry.
Ref: class-extrapolation from cedarwood-atlas, cedarwood-himalayan (Cupressaceae sesquiterpene anti-inflammatory class)
α-Cadinol demonstrated in vitro cytotoxicity against HT-29 human colon adenocarcinoma cells; constituent-class research context only — does NOT constitute a therapeutic claim at aromatherapy dilutions.
Ref: He K, Zeng L, Ye Q et al. (1997a). Planta Medica 63:158-160
Cadinane sesquiterpenes and cedarwood-type volatile fraction deter insects via olfactory and contact mechanisms; Cupressaceae wood oils are widely established in natural insect-deterrent formulations.
Ref: class-extrapolation from cedarwood-virginian, cedarwood-atlas (Cupressaceae wood insect-deterrent class)
AI-summary
No RCT-grade clinical trials specific to Port Orford cedarwood oil (Chamaecyparis lawsoniana) were identified. Craig et al. (2004) conducted a Local Lymph Node Assay (LLNA) and standard dermal irritation testing, confirming non-sensitizing and non-irritating status at standard aromatherapy concentrations — directly supporting the 5.0% adult dermal framework cap (Tisserand & Young 2014, p.513-514). Tucker et al. (2000) characterized the essential oil composition. The α-cadinol constituent class shows in vitro cytotoxicity against HT-29 colon cancer cells (He et al. 1997a) — research context only, not a clinical therapeutic claim. Remaining therapeutic applications are extrapolated from the well-studied cedarwood-atlas, cedarwood-virginian, and hinoki-wood Cupressaceae cluster. Traditional aromatherapy use; no RCT-grade therapeutic efficacy data located for this specific species.

| Phương pháp | Liều lượng | Ghi chú |
|---|---|---|
| Diffusion | 3-5 drops in 100 ml water, 30-60 min session | Primary use for grounding and stress relief. Blends well with other Cupressaceae, resinous, and citrus oils. Avoid continuous diffusion in unventilated spaces. |
| Topical massage | 1-3% in carrier oil (max 5.0% adult) | Suitable for full-body or localized massage targeting muscle tension or respiratory support on chest/back. Use jojoba or sweet almond. Precautionary avoidance in first trimester advised. |
| Skincare / facial blend | 0.5-1% in carrier | Best suited for oily and combination skin; use with jojoba or light carrier. For mature skin pair with rosehip seed oil. Patch test on sensitive skin before full application. |
| Steam inhalation | 2-3 drops in bowl of steaming water | 5-10 minute session for respiratory support. Keep eyes closed. Avoid for young children and those with reactive airways or asthma. |
| Bath | 4-6 drops pre-blended in 5 ml carrier oil | Pre-disperse in carrier before adding to bath water; undiluted drops may cause skin irritation. Relaxing evening use. Not recommended for children under 6 years. |
