As well as one of the oldest known spices, cinnamon is used as a herbal medicine. Both the bark and oil distilled from the bark and leaves are used. Although the bark and the leaves contain essential oils, the content of eugenol is much higher in the leaves, up to 80%.

Cinnamon bark has analgesic, anti-inflammatory, antioxidant, antibacterial, anti-protozoal and fungitoxic properties. It has been used for thousands of years to treat nausea and vomiting, diarrhoea, rheumatism, colds, and hypertension.

Cinnamon leaf oil is antiseptic and anaesthetic due to the eugenol content.
