Chinese medicine for treatment of chronic hepatitis B

Contemporary Western medicines approved by the U.S. Food and Drug Administration (FDA) for the treatment of chronic hepatitis B (CHB), although available in China, have high costs, or major side effects and limited effectiveness. Research efforts have focused on looking for natural products as alternative medicines with low cost and good safety for CHB treatment. Chinese medicine (CM) has ancient, time-honored theories about methods of diagnosis and treatment for liver diseases. In recent decades, a large number of clinical trials and pre-clinical studies, which were performed in China and other countries, indicated that CM has potential benefit in several aspects of the treatment of CHB, e.g., anti-inflammatory, anticancer, antioxidant, immunomodulating, antifibrosis, and antiviral. However, there are many concerns regarding the study design and the quality of clinical trials. Further larger, stringently designed, double-blind, placebo control, randomized clinical trials and long-term follow-up are needed to provide conclusive evidence of their efficacy and safety. Components of CM deserve further study in pre-clinical models of HBV infection and in clinical trials world-wide.
