Nutrition and Herbal Medicine in Hepatitis: Mechanisms, Clinical Evidence, and Future Directions

Abstract

Hepatitis is a widespread liver disease with inflammation of the liver and continues to be a significant global health problem. It can result from exposure to toxic chemicals, certain drugs, autoimmune diseases, metabolic disorders, alcohol abuse or viral infections. Untreated chronic liver inflammation can cause liver fibrosis, cirrhosis, liver failure, and liver cancer (hepatocellular carcinoma). While antiviral treatment is the main treatment for viral hepatitis; supportive measures like appropriate nutrition and herbal medicine can positively influence liver health and patient outcomes. A proper diet supplies the necessary nutrients needed for normal liver function, to boost the immune system, to lessen oxidative stress and to promote repair of the damaged liver cells. A nutritious diet with good quality protein, healthy fats, and vitamins, minerals, dietary fibre and foods high in antioxidants can support liver function and slow the progress of disease. The attention is also paid to herbal medicine, as many medicinal plants contain bioactive compounds, possessing antioxidant, anti-inflammatory, antiviral and hepatoprotective properties. In experimental studies, and selected clinical trials, medicinal plants like Silybum marianum, Curcuma longa, Phyllanthus niruri, Glycyrrhiza glabra and Andrographis paniculata have exhibited promising activities of hepatoprotection, anti- inflammatory and antioxidant properties. There are, however, important challenges in their routine clinical use as a result of differences in herbal formulations, lack of standardization, limited high quality clinical evidence and potential herb-drug interactions. This paper reviews the pathogenesis of hepatitis, the importance of nutrition for liver health and the existing scientific evidence of herbal remedies. It also emphasizes safety issues, gaps in existing research, and future directions for evidence-based nutrition and herbal interventions to enhance the care of hepatitis.
