What’s the difference between Cinnamon Bark and Cassia essential oils? Is one better than the other?

While often thought to be the same, Cinnamon Bark and Cassia essential oils have distinct differences along with some similarities. Although extracted from different species (Cinnamon Bark from Cinnamomum zeylanicum, and Cassia from Cinnamomum cassia) they are both widely referred to as cinnamon and often used for similar purposes. Cinnamon is distilled from the bark of the cinnamon tree while Cassia is distilled from the stems and bark of the cassia shrub. Trans-cinnamaldehyde is the primary constituent in both, though the concentration is the primary chemical difference. Neither oil is better; however, the variance in aldehyde composition results in different ranges of benefits. I recommend Cinnamon Bark to support oral health and to purify the air, while Cassia elevates mood and promotes healthy digestive function.*
