Cinnamomum verum generates two types of essential oil as leaf oil and bark oil. This bark oil (known as liquid cinnamon) contains cinnamaldehyde while eugenol is the major constituent in leaf oils.

Leaf oil

The cinnamon leaf oil obtains through steam distillation on collected leaf and twigs that remains on the cultivation after harvesting. Cinnamomum verum leaf oil contains higher amount of eugenol (68 – 87%) and less amount of cinnamaldehyde (0.5 – 1%).

The leaves are obtained as a by-product of the industry. The leaf oil is cheaper than bark oil and internal consumption not recommended.

Bark oil
The other form of essential oil, the bark oil is the result of steam distillation of cinnamon bark. This contains mostly cinnamaldehyde (63 – 75%) and eugenol (2 – 13%).

The cinnamon bark oil is one of the expensive essential oils in the market. The quality of bark oils depend on the material used to distill the oil. Quills are always recommended to obtain high quality bark oil, but it is not always used for the distillation.

Cassia oil
Unlike the two categories of Sri Lanka cinnamon oil, only one category of essential oil exists in cinnamomum cassia. This is because Cassia oil is distilled from a mixture of many parts of the tree. So, there is only one type of cassia oil exists.
