Guide To Cassia Essential Oil Benefits and Uses

Cassia essential oil (Cinnamomum cassia) is strong and can easily irritate skin. Some sources recommend not using the oil in home aromatherapy.

Cassia bark oil is almost identical to and has most of the same uses as cinnamon bark oil. Unfortunately, commercial cassia bark is commonly adulterated, according to Aromatica: A Clinical Guide to Essential Oil Therapeutics, Volume 2. Several sources suggest cinnamon bark is a better choice than cassia.
