Herbal drugs have gained significant attention in the treatment of diabetes mellitus due to their perceived safety and potential efficacy. This review explores the current landscape of herbal remedies used in managing diabetes, focusing on their mechanisms of action, clinical effectiveness, and safety profiles. Various herbs such as bitter melon, fenugreek, ginseng, and cinnamon have been studied for their antidiabetic properties, often targeting insulin sensitivity, glucose metabolism, and pancreatic function. Despite promising findings from preclinical and some clinical studies, rigorous scientific validation and standardization of herbal therapies remain essential to establish their efficacy and safety. Challenges including variability in active compounds, bioavailability issues, and potential herb-drug interactions necessitate caution in their use alongside conventional treatments. Nevertheless, herbal drugs represent a valuable adjunct or alternative in diabetes management, highlighting the need for further research to elucidate their full therapeutic potential.
