Cinnamon could potentially exhibit pharmacological effects in treating type 2 diabetes mellitus and insulin resistance. The plant material predominantly employed in the study was sourced from Chinese cinnamon (see Chinese cinnamon's medicinal uses).[2][3] Recent phytochemical research has suggested that cinnamtannin B1, extracted from C. Verum, might have a potential therapeutic impact on type 2 diabetes,[4] with the exception of postmenopausal patients studied using Cinnamomum aromaticum.[5]

Cinnamtannin B1 possesses multiple phenolic hydroxyl groups and is noted for its antioxidant properties, antimicrobial activities, and ability to inhibit platelet aggregation,[6] which could contribute to the protection of damaged tissues in wounds.[7]
