High levels of sugar in the blood caused by elevated levels of insulin or insufficiency are a hallmark of diabetes mellitus, a chronic metabolic condition that affects millions of individuals worldwide. Diabetes typically requires long-term use of synthetic drugs, which may lead to complications and negative outcomes. Interest in the use of plant-based medications has increased since they are believed to be safer, cost-effective, and more effective than alternative options. Research is now being conducted on the potential therapeutic applications of numerous medicinal plants which have been extensively used for decades in conventional treatments for treating and controlling diabetes. Numerous plants are thought to have chemicals that can boost overall metabolic function, enhance insulin sensitivity, and assist control blood glucose levels These plants work in a number of ways, including as encouraging the release of insulin, enhancing the cells ability to absorb glucose, and inhibiting the enzymes responsible for breaking down carbohydrates. Among the bioactive compounds included in these plants that support their antidiabetic effects are alkaloids, flavonoids, saponins, & polyphenols. The purpose of this study is to examine the use of plants used for medicinal purposes in the treatment of diabetes and to stress the significance of further research to completely comprehend their safety and effectiveness. With the rising global prevalence of diabetes, plant-based treatments represent a promising complementary approach to conventional therapies, offering new hope in the management of this widespread condition.
