Latin Name: Cinnamom zeylanicum
Family: Lauracae
Cinnamon is a common spice, coming from the bark or leaves of the tropical Coppiced tree. It is one of the most potent antimicrobial essential oils, tested against hundreds of bacteria and fungi. It has also shown the ability to help lower blood sugar and cholesterol levels, and may be useful as an insecticidal and repellent. More research is needed.
