糖尿病属于中医“消渴”的范畴。消渴以阴虚为本，燥热为标，但机体阳气易被痰瘀所阻，并可阴损及阳，导致阴阳两虚。故消渴的治疗要重视扶阳，保护机体阳气。基于扶阳学说对消渴的认识，扶阳药肉桂能有效治疗糖尿病。肉桂能改善糖脂代谢和胰岛素抵抗，保护胰岛β细胞和促进胰岛素分泌，具有抗炎、抗氧化的作用，并能抑制AGEs形成及其诱导的病理生理效应，促进伤口愈合。本研究探讨扶阳药肉桂防治糖尿病的科学内涵有助于进一步丰富扶阳学说理论，并为临床应用肉桂防治糖尿病提供新策略和科学依据。

Diabetes belongs to “Xiaoke” in Traditional Chinese Medicine. Xiaoke attributes to Yin deficiency, indicating heat as external manifestation. Yang is easily blocked by phlegm-blood stasis, and Yin deficiency impairs Yang, thus leading to the deficiency of Yin and Yang. Therefore, supporting Yang and protecting Yang should be paid more attention during the treatment of Xiaoke. Based on the understanding of Xiaoke according to Fuyang Theory, Fuyang medicine Cinnamomum can effectively treat diabetes. Cinnamomum improves glycolipid metabolism and insulin resistance, protects pancreatic β cells and promotes insulin secretion, has anti-inflammatory and anti-oxidative effects, and inhibits the formation of advanced glycation end-products, accelerates wound healing. To reveal the scientific connotation of Fuyang medicine Cinnamomum in preventing and treating diabetes will be helpful to further enrich the theory of Fuyang Theory and provide new strategies and scientific basis for the prevention and treatment of diabetes using Cinnamomum in clinic.
