Eat Healthy Foods for Life
In medicine it acts like other volatile oils and once had a reputation as a cure for colds. It has also been used to treat diarrhea and other problems of the digestive system. Cinnamon is high in antioxidant activity. The essential oil of cinnamon also has antimicrobial properties, which can aid in the preservation of certain foods. Cinnamon has been reported to have remarkable pharmacological effects in the treatment of Type 2 diabetes mellitus and insulin resistance. However, the plant material used in the study was mostly from cassia and only few of them are truly from Cinnamomum zeylanicum (see cassia's medicinal uses for more information about its health benefits). Recent advancement in phytochemistry has shown that it is a cinnamtannin B1 isolated from C. zeylanicum which is of therapeutic effect on Type 2 diabetes, with the exception of the postmenopausal patients studied on C. cassia. Cinnamon has traditionally been used to treat toothache and fight bad breath and its regular use is believed to stave off common cold and aid digestion.
It is reported that regularly drinking of Cinnamomum zeylanicum tea made from the bark could be beneficial to oxidative stress related illness in humans, as the plant part contains significant antioxidant potential. Cinnamon has been proposed for use as an insect repellent, although it remains untested. Cinnamon leaf oil has been found to be very effective in killing mosquito larvae. The compounds cinnamaldehyde, cinnamyl acetate, eugenol, and anethole, that are contained in cinnamon leaf oil, were found to have the highest effectiveness against mosquito larvae. Reference
