Tinh dầu tuyết tùng Virginia

Chemistry insight:

• Sesquiterpene hydrocarbon ≈60% + sesquiterpene alcohol ≈25%. Profile rất stable — KHÔNG monoterpene oxidation risk, KHÔNG ester hydrolysis concern.
• Zero himachalene / atlantone content → sharp compositional contrast với Atlas/Himalayan (Pinaceae Cedrus). GC-MS authentication trivial.
• Cedrol là therapeutic lead constituent — anxiolytic + antitussive + reported hair-follicle stimulant.

• Hô hấp: Expectorant + antitussive (cedrol — Kagawa 2003).
• Anxiolytic + sedative: Inhalation cho mild anxiety / sleep support (Dayawansa 2003).
• Da liễu: Da dầu/mụn astringent; chăm sóc tóc + hair-follicle stimulation (historical).
• Insecticidal / repellent: Truyền thống cedar-closet moth repellent.
• Perfumery: Masculine fougère + chypre anchor; incense base; low-cost sandalwood alternative.

• Five-element: Kim (Metal — phổi, hô hấp, structural; dry-woody archetype) + subtle Thổ (Earth — grounding).
• TCM: Không classical Chinese placement cho Virginian (American species; Chinese analogue là Cupressus funebris 柏 bǎi).
• Western aromatherapy: Grounding + focusing + clearing; Mojay classifies assertive-masculine.
