ABSTRACT

Diabetes mellitus is a chronic metabolic disorder characterized by hyperglycemia and disturbances in insulin signaling, affecting millions globally. The management of diabetes often involves pharmacological treatments, though these can be associated with adverse effects and long-term complications. In recent years, the therapeutic potential of phytochemicals derived from plants has emerged as an alternative or adjunctive approach in diabetes management. Phytochemicals such as polyphenols, flavonoids, alkaloids, and terpenoids possess antioxidant, anti-inflammatory, and anti-hyperglycemic properties, which may mitigate the pathophysiological processes underlying diabetes. This review explores the various mechanisms by which phytochemicals exert their effects on glucose homeostasis, including modulation of insulin sensitivity, inhibition of carbohydrate digestion, and regulation of oxidative stress. Furthermore, we discuss the clinical efficacy of these compounds in human trials and preclinical models, highlighting their potential as adjuncts to conventional therapies. While promising, the safety concerns associated with the use of phytochemicals, including toxicity and drug interactions, must be addressed to ensure their clinical applicability. This article provides a comprehensive overview of the mechanisms, efficacy, and safety concerns of phytochemical interventions in diabetes, aiming to offer a balanced perspective for their future integration into diabetes management protocols.
