A LITTLE CARE GOES A LONG WAY
Using it thoughtfully
Read the full safety context before bringing this oil into your routine.
- Cited dermal maximum · leave-on
- No restriction cited
- Phototoxicity
- Not flagged in this profile
- Oxidation risk
- low
A cited maximum is a limit, not a suggested dilution. Missing restrictions do not establish safety.
No phototoxic furocoumarin restriction was identified for Siam wood oil in the reviewed public sources.
Contraindications & cautions
- majorRetail/professional safety guidance states Siam wood essential oil is strictly contraindicated in pregnant and breastfeeding women, and contraindicated for general use in women, due to lack of dedicated reproductive-toxicity data on Fokienia hodginsii oil.
- majorContraindicated for use with children per supplier safety guidance; not for internal use without medical advice.
- mildContains farnesol, a recognized fragrance allergen; risk of allergic reaction if overdosed in blends, so use should be moderated in mixtures.

THE SCIENCE BEHIND THE SCENT
Inside the oil
An oil's character comes from its natural chemical composition. Explore each constituent to understand the connections.
About this composition
Hermitage Oils identifies this material as a 14-year-aged Siam wood essential oil from Vietnam and describes it as full of warm cedarwood, cabreuva, and amyris character with trace satsuma nuances. Public aged-lot GC data was not exposed on the product page during this pass, so the constituent list below is anchored to public Siam wood chemistry from the same botanical and process family rather than a product-specific aged assay. That preserves a usable draft while explicitly naming the missing source still required for a fully product-specific profile.

- traditionally used in aromatherapy for grounding, calming effects similar to other woody base oils
- reported to support relaxation in diffuser and massage blends
- used as a natural fixative in fine fragrance and blending work
- traditionally associated with a warm, earthy, meditative atmosphere

What we're still learning · 3 data gaps
Good decisions start with knowing what is — and isn't — in the evidence.
- No public aged-lot GC/COA was exposed for the Hermitage 14-year-aged product, so the constituent percentages are only species-and-process matched rather than product-specific.
- The stored 100% dermal maximum is only a partial archive normalization of the reviewed public Siam wood safety statement 'No known safety concerns'; a public IFRA certificate, product-specific safety sheet, or monograph that publishes an exact maximum dermal percentage for the aged Hermitage material or Siam wood generally is still missing.
- The public Siam wood COA used as a chemistry proxy reports beta-eudesmol and alpha-eudesmol as a combined peak rather than separate quantified constituents.
