Cinnamomum cassia (Cinnamomum aromaticum), organically produced, steam-distilled bark, Vietnam.


We've resisted offering this spicy-scented oil for a long time, but requests keep coming in for it, so here it is. Sometimes called Chinese Cinnamon, Cassia is softer scented than true Cinnamon Bark. Debi says it smells just like Dentyne Gum, to her nose.

Cassia's chemical constituents should make it a powerful germ killer, possibly useful in a diffuser blend. We use it in our Germ Beater.

WARNING: We do not recommend Cassia's use in any topical blends because it is a hazardous oil, a dermal and mucous membrane irritant, a known sensitizer, and possible dermal toxin, easily absorbed into the skin. Robert Tisserand recommends a maximum topical dilution of 0.05% (that is 1/20th of one percent). Tisserand advises that Cassia Oil may contain methyleugenol; may inhibit blood clotting, embryotoxicity, skin sensitivity (high risk), mucous membrane irritation (low risk).  Contraindicated during pregnancy and breastfeeding, before major surgery, peptic ulcers, hemophilia, other bleeding disorders.  May interfere with medications for diabetes and anticoagulants.   One of the few oils to contain coumarin.  Cassia and cinnamaldehyde are more toxic dermally than orally.

**For other possible oils to avoid, please see our Contraindications page.

BLENDS WITH: Citrus, wood notes, and other spices.
