Adam Michael has this to say “This essential oil is produced by steam distillation of the twigs and leafs from the White Cedar tree in Canada, clear in colour and of a pourable viscosity. The aroma is camphoraceous, fresh, green and herbal agrestic. Blends well with artemisia, lavender and sage materials.

Also known as Thuja, this oil contains approximately 55% alpha thujone and 15% Fenchone. Thujone is a proven skin irritant and in high enough dose capable of poisoning. Fenchone, also naturally found in fennel, has a somewhat sweet and slightly floral tint in pure form, and has been proven to cause epileptic type convulsions when administered in very large doses.”

Arctander has this to say “Its green, sweet-herbaceous, although medicinal and camphoraceous-minty note blends well with pine needle oils, citrus oils, lavandin and rosemary in chypre or fougere bases. The oil has even been used as a piquant topnote in high class perfumes.”
