Abstract

Momordica charantia (bitter melon) is a significant medicinal plant, having been long used in traditional medicine in Asian, African and South American systems. M. charantia is more than a traditional medicine; by consolidating existing evidence, it is a promising source of drug discovery and can serve as a complementary in contemporary therapeutics. Over the last several decades, it has become the subject of contemporary biomedical studies due to its abundance of phytochemicals, such as saponins, flavonoids, alkaloids, and polypeptides. These bioactive compounds present a wide range of pharmacological processes that M. charantia can be a natural solution to some of the most urgent health issues. There is promising evidence of its strong antidiabetic potential, via regulation of glucose metabolism and insulin signalling, and its anticancer potential is associated with inducing apoptosis and inhibiting tumour growth pathways. In addition, antioxidant, anti-inflammatory, antimicrobial, hepatoprotective, and immune-modulatory properties further underscore its therapeutic versatility. This review summarizes the limited current preclinical and clinical evidence, where the mechanisms that mediate such effects are critically examined. Although the incorporation of M. charantia into complementary and alternative medicine has been promising in terms of data, drawbacks such as differences in bioactive content, standardization of formulations, and clinical validation of large-scale research are still translation challenges. The research must be directed toward clinical validation, safety profiling and standardization of preparations in future to unlock its full medicinal potential.
