Cinnamtannin B1 is a condensed tannin found in Cinnamomum verum. It is a type A proanthocyanidin.^[1]

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 C. Cassia.^[5]
