ABSTRACT

Liver diseases, including metabolic dysfunction-associated steatotic liver disease (MASLD), alcoholic liver disease, drug-induced liver injury, viral hepatitis, liver fibrosis, cirrhosis, and hepatocellular carcinoma, remain major global health challenges owing to their increasing prevalence, complex pathogenesis, and limited therapeutic options. Growing interest in plant-based therapeutics has highlighted Vernonia amygdalina Delile (Asteraceae), commonly known as bitter leaf, as a promising medicinal plant with significant hepatoprotective potential. This review comprehensively summarizes the phytochemistry, pharmacological mechanisms, therapeutic applications, and emerging drug delivery strategies of V. amygdalina in the prevention and management of liver diseases. The plant is rich in diverse bioactive constituents, including sesquiterpene lactones, flavonoids, phenolic acids, steroidal saponins, terpenoids, tannins, and alkaloids, which collectively exhibit potent antioxidant, anti-inflammatory, antifibrotic, anti-apoptotic, immunomodulatory, hypolipidemic, and anticancer activities. These effects are mediated through the modulation of multiple molecular signaling pathways, including Nrf2/HO-1, NF-κB, PI3K/Akt, MAPK, TGF-β/Smad, AMPK, PPARα/PPARγ, and SIRT1, thereby targeting key mechanisms involved in hepatic injury, oxidative stress, fibrosis, metabolic dysfunction, and carcinogenesis. Furthermore, this review discusses the therapeutic potential of V. amygdalina across various liver disorders, recent advances in nanotechnology-based drug delivery systems to overcome bioavailability limitations, and the role of artificial intelligence and precision phytotherapy in accelerating phytopharmaceutical development. Future multidisciplinary research integrating standardized phytochemical characterization, advanced nanoformulations, robust clinical trials, and precision medicine approaches is essential to establish V. amygdalina as a safe, effective, and evidence-based phytotherapeutic agent for liver disease prevention and management.
