OBJECTIVES: The study was planned to evaluate the efficacy and safety of Livwin (polyherbal formulation) in acute viral Hepatitis. MATERIALS AND METHODS: In this study, there were 29 patients in each group, receiving either Livwin (containing ashwaganDHA, Arjuna, Bhumyamalaki, Daruharidra, Guduchi, Kutki and Punarnava) or placebo capsules containing lactose powder (500 mg). Both drugs were given orally two capsules two times a day for eight weeks followed by treatment free period of four weeks. Recovery of patients was assessed by noting symptomatic recovery and by measuring levels of serum bilirubin, serum aspartate aminotransferase (AST), serum alanine aminotransferase (ALT), alkaline phosphatase at baseline, 2, 4, 8 and 12 weeks. RESULTS: Significant earlier recovery of weakness was observed with Livwin as compared to placebo at 2, 4 and 8 weeks. Serum bilirubin and ALT was observed in normal range in significantly more number of patients with Livwin treatment as compared to placebo at 2, 4 and 8 weeks. AST was observed in normal range in significantly more number of patients with Livwin treatment as compared to placebo at 2 and 4 weeks. CONCLUSIONS: Livwin is found effective in uncomplicated patients of acute viral Hepatitis. Epigastric pain and diarrhea were reported with Livwin treatment.
