Plant-Based Bioactive Compounds in the Prevention and Management of Liver Disorders: A Review

Hepatotoxicity is basically harm or else weakening of the liver functioning brought on by a variety of substances, including alcohol, medications, endotoxins, and environmental factors. Because of its high blood perfusion rate and high level of enzymatic activity, the liver, which serves as the primary metabolic and detoxifying organ, is especially vulnerable to these types of attacks. Exposure to these agents may lead liver steatosis, fibrosis, cirrhosis, and hepatocellular carcinoma. The mechanisms involved in hepatotoxicity are oxidative stress, mitochondrial dysfunction, immune-mediated injury, lipid peroxidation, bile-related damage, and ischemic injury. Conventional therapies mostly offers limited protection, highlighting the growing interest in phytoconstituents with hepatoprotective potential. A wide range of natural compounds such as resveratrol, curcumin, catechins, carotenoids, quercetin, ursolic acid, silymarin, schisantherin, and saikosaponin have been widely examined for their antioxidant, anti-inflammatory, and anti-apoptotic properties. These plant based bioactive compounds lowers the inflammation, oxidative stress, and cellular death by regulating important cell signaling networks such as NF-κB, MAPK, PI3K/Akt, and Nrf2. Also, they enhance insulin sensitivity, control lipid metabolism, and stop the growth of fibrosis, all of which assist to a multi-focus treatment strategy. Clinical and preclinical research confirms their use in the prevention and management of various liver conditions. Though, challenges such as bioavailability, optimal dosage, and long-term safety remain key barriers to clinical translation. Overall, the incorporation of phytoconstituents into therapeutic approaches delivers a promising path for hepatoprotection and the prevention of chronic liver diseases.
