Cassia Bark Essential Oil (Cinnamomum cassia)
Cassia Bark may also be referred to as Chinese cinnamon or cassia. It is typically processed using steam distilled as a method for extracting oil from the bark.
Resembling Cinnamon Bark Essential Oil in aroma, Cassia Bark Essential Oil is sometimes used as an economical substitute within fragrancing applications.
It is my understanding that most of the "Ground Cinnamon" that we purchase in grocery stores, and even most of the "Cinnamon Sticks" that are sold are not true cinnamon, but are really its more affordable cousin, Cassia, Cinnamomum cassia.

Cautions & Safety
Cautions when using Cassia Bark:
Tisserand and Young caution that there is a high risk of skin sensitization when using Cassia Oil (the bark or leaf oil) and recommend a dermal maximum of 0.05%. They indicate that it may inhibit blood clotting and that it is contraindicated in pregnancy/breastfeeding. Avoid use with children under 2. Reading Tisserand and Young's full profile is recommended. [Robert Tisserand and Rodney Young, Essential Oil Safety (Second Edition. United Kingdom: Churchill Livingstone Elsevier, 2014), 235.]
This essential oil poses a higher risk of causing irritation and sensitization when used in the bath. Avoid using it in the bath, even if it is solubilized/diluted.
Safety Precautions for Cassia Bark:
Do not take any oils internally and do not apply undiluted essential oils, absolutes, CO2s or other concentrated essences onto the skin without advanced essential oil knowledge or consultation from a qualified aromatherapy practitioner. If you are pregnant, epileptic, have liver damage, have cancer, or have any other medical problem, use oils only under the proper guidance of a qualified aromatherapy practitioner. Use extreme caution when using oils with children and be sure to first read there commended dilution ratios for children. Consult a qualified aromatherapy practitioner before using oils with children, the elderly, if you have medical issues or are taking medications. For in-depth information on oil safety issues, read Essential Oil Safety by Robert Tisserand and Rodney Young.
