Diabetes mellitus (DM) is a chronic progressive systemic disease caused by a metabolic disorder. In recent years, a large number of studies have shown that certain traditional Chinese medicines and their bioactive ingredients have obvious hypoglycemic effects. This literature review focuses on medicine food homology (MFH) and medicinal health food (MHF) species used in China with a hypoglycemic function and emphasizes the bioactive ingredients and their pharmacological effects. The bioactive ingredients of MFH and MHF have been divided into six categories: saponins, flavonoids, terpenoids, alkaloids, polysaccharides, and others; and their sources, models, efficacy, and mechanisms of action have been described. It is noteworthy that the mechanisms of the bioactive ingredients of MFH and MHF with hypoglycemic effects have been summarized as follows: a) insulin-mimetic effects and restoration of the damaged pancreas; b) effect on glucose metabolism; c) increased insulin sensitivity and improved insulin resistance; and d) regulation of intestinal flora. We conclude that this review provides useful data and information to support the further investigation and application of MFH and MHF to treat DM.
