- Callitris glaucophylla Joy Thomps. & L.A.S. Johnson (Cupressaceae) — steam distillate from wood. Synonyms: Cypress pinewood, white cypress, white cypress pine. Same genus as [[cypress-blue]] + [[cypress-emerald]] but DIFFERENT chemistry + DIFFERENT common-name history.
- Hazards: None known. Cautions: Low blood pressure. (T&Y verbatim p.558).
- Max dermal — no specific T&Y quantitative limit; framework default 5.0% adult. Non-phototoxic (wood steam distillate). Adverse skin reactions: no information found for jade cypress oil or any of its major constituents.
- Acute toxicity — no information for jade cypress oil or any of its major constituents. Oil contains no known carcinogens.
- Key rails: Guaiol 14.7% + α-eudesmol + β-eudesmol (combined 10.1%) → hypotensive effect (Arora et al 1967) → LOW BLOOD PRESSURE oral caution. CRITICAL species-confusion rail — T&Y Comments verbatim: "This oil is sometimes mistakenly referred to as deriving from Callitris columellaris (see previous profile)." → do NOT conflate with [[cypress-emerald]] (C. columellaris) despite common-name overlap in supply chains. 4-variant cypress family disambiguation CRITICAL — see §12.

Pha Chế & Hòa Hợp
hypotensive
Guaiol and β-eudesmol, dominant sesquiterpene alcohols in the wood fraction, demonstrated blood-pressure-lowering activity in animal models, suggesting peripheral vasodilatory action.
Ref: Arora et al (1967), cited in Tisserand & Young 2014, Ch.13 p.558–559
grounding / mood-stabilising
Dense sesquiterpene-alcohol-rich wood aroma activates olfactory pathways associated with parasympathetic modulation, consistent with base-note woody inhalation aromatherapy tradition.
Ref: Tisserand & Young 2014, Ch.13 p.558–559 (traditional aromatherapy framing)
insect-repellent / timber-protective
Callitris heartwood sesquiterpenes including guaiol deter wood-boring insects; the property underpins traditional Australian white cypress pine timber use referenced in the T&Y entry.
Ref: Tisserand & Young 2014, Ch.13 p.558–559; Condon (private communication, 2002)
antimicrobial (broad-spectrum, class-level)
Sesquiterpene alcohols such as guaiol and eudesmol analogues confer membrane-disrupting antimicrobial activity documented across Cupressaceae wood oils.
Ref: class-extrapolation from guaiacwood (Bulnesia sarmientoi) — analogous guaiol/bulnesol sesquiterpene-alcohol-dominant wood oil
deodorising
Persistent woody-earthy volatile profile suppresses malodour-producing surface bacteria, characteristic of dense sesquiterpene wood oils used in deodorant and masculine fragrance bases.
Ref: class-extrapolation from Virginia cedarwood (Juniperus virginiana) and Atlas cedarwood (Cedrus atlantica) — Cupressaceae sesquiterpene-class peers
AI-summary
No RCT-grade clinical evidence has been located for Callitris glaucophylla wood oil in human trials. The strongest pharmacological data is Arora et al (1967), who demonstrated hypotensive effects of guaiol and β-eudesmol — both identified as prominent wood-fraction constituents via Condon (private communication, 2002) — in animal models. This provides mechanistic plausibility for cardiovascular-calming use but has not been replicated in controlled human studies. Tisserand & Young (2014, Ch.13 p.558–559) frame the oil primarily within safety parameters. All broader therapeutic claims rest on the analogous Cupressaceae wood-oil class rather than Callitris-specific evidence. Traditional aromatherapy use predominates.

| Phương pháp | Liều lượng | Ghi chú |
|---|---|---|
| Diffusion | 3–5 drops in 100 ml water or per diffuser reservoir | Blend với sandalwood, vetiver hoặc bergamot FCF để tạo hương nền ấm, mộc mạc. Khuếch tán 30–60 phút/phiên. Không pha loãng khi khuếch tán. |
| Topical massage | 1–3% in carrier oil (adult max 5%) | Ưu tiên pha trong jojoba hoặc sweet almond. Patch-test 24h trước lần đầu. Thận trọng 3 tháng đầu thai kỳ — chưa đủ dữ liệu an toàn riêng cho loài này. |
| Inhalation (direct) | 1–2 drops on tissue or inhaler stick | Hít thở sâu 5–10 lần; giữ khoảng cách 2–3 cm. Phù hợp khi cần tập trung hoặc giảm căng thẳng nhanh. |
| Bath | 5–8 drops dispersed in 1 tsp carrier oil before adding to bathwater | Luôn pha loãng vào dầu nền trước khi cho vào bồn. Ngâm 15–20 phút. Tránh dùng cho trẻ dưới 5 tuổi. |
| Skincare blend | 0.5–1% in unscented base cream or facial serum | Phù hợp da dầu và da hỗn hợp. Tránh dùng liên tục trên da nhạy cảm chưa patch-test — chưa có dữ liệu HRIPT riêng cho loài. |
Dầu nền phù hợp
Jojoba oilLight non-comedogenic wax ester that complements the dry woody character without masking scent; ideal for oily and combination skin.
Sweet almond oilMild oleic-rich carrier that softens skin and extends massage absorption, well-suited for relaxation blends.
Fractionated coconut oilOdour-neutral fast-absorbing MCT base that preserves the oil’s natural dry-woody aroma signature.
Argan oilHigh oleic/linoleic ratio with natural tocopherols pairs well with sesquiterpene-alcohol-rich wood oils in mature or dry-skin formulations.
