Diabetes mellitus is a chronic metabolic disorder that has become a major global health burden due to its progressive complications and rising prevalence. It is associated with long-term damage to vital organs, including the heart, kidneys, eyes, and nerves, thereby contributing significantly to morbidity and mortality worldwide. Although several synthetic anti-diabetic are currently available, their long-term use is often accompanied by adverse effects such as hypoglycemia, gastrointestinal disturbances, and reduced therapeutic efficacy. These limitations highlight the urgent need for safer, more effective alternatives to improve diabetes management. In this context, medicinal plants have emerged as promising candidates, as they not only help regulate blood glucose but also offer additional health benefits with fewer side effects compared to conventional drugs. Among the medicinal plants investigated for antidiabetic potential, Cinnamomum cassia and Terminalia catappa have attracted considerable attention. These plants are rich in bioactive phytochemicals such as cinnamaldehyde, flavonoids, tannins, and terpenoids, which demonstrate hypoglycemic, antioxidant, and β-cell rejuvenate properties. Animal model studies have shown that these plants can effectively lower blood glucose and enhance insulin sensitivity, thereby protecting against diabetes-induced complications. The growing interest in medicinal plants reflects their potential as safer and multifunctional therapeutic options. By integrating these natural agents into diabetes management strategies, it may be possible to achieve better glycemic control while minimizing adverse effects. These results strongly indicate the potential of medicinal plant as complementary therapeutic agents, supporting progressive efforts to combine medicinal plants into diabetes management strategies.
