Cinnamon could have some pharmacological effects in the treatment of type 2 diabetes mellitus and insulin resistance. The plant material used in the study was mostly from Chinese cinnamon (see Chinese cinnamon's medicinal uses).[2][3] Recent studies in phytochemistry have indicated that cinnamtannin B1 isolated from C. Verum bears possible therapeutic effect on type 2 diabetes,[4] with the exception of the postmenopausal patients studied on Cinnamomum aromaticum.[5]

Cinnamtannin B1 possesses several phenolic hydroxyl groups and is reported to exhibit antioxidant property, antimicrobial activities, and anti-platelet aggregation[6] that may protect damaged tissues in wounds[7]
