Interventions

Patients with chronic hepatitis C who were not responsive or not suitable for standard interferon-based therapy are enrolled into this study. Patients are diagnosed first by Chinese herbal doctor to identified as “dampness heat stasis” and “liver Qi stagnation” by Bian-Zheng-lun-zhi (diagnosis and treatment with Traditional Chinese Medicine) and then randomized and allocated to receive Rong-Yang-Jyh-Gan-Tang (a combination of long-dan-xie-gan-tang, jia-wei-xia-yao-san, dan-shen and hou-po and ma
