In vitro hepatoprotective activity of a polyherbal formulation on HepG2 cell line

Abstract

Background: In Ayurveda, use of multiple herbs in a single formulation is popular and polyherbal Ayurvedic formulations are widely used as growth promoters, gastrointestinal and hepatic regulators, hepatic tonics and so on. Despite the widespread use, there is a lack of scientific evidence on their efficacy and safety. Aim: This study was undertaken to validate the efficacy by evaluating the hepatoprotective activity of one such polyherbal blend (LIVT) on HepG2 cell line. Materials and Methods: Four doses of test formulation (62.5, 125, 250 and 500 μg/ml) were tested on D-galactosamine induced HepG2 cell toxicity model. MTT assay was performed to determine the dose range for the hepatoprotective study. Results: The test formulation exhibited significant (P < 0.05) cytoprotective activity with a maximum protection of 37% at dose 62.5 μg/ml, and the activity was comparable with that of the standard, silymarin. Conclusion: The results of the present study indicate that the polyherbal blend demonstrated a significant hepatoprotective activity and could be used as an active herbal alternative for the treatment of liver ailments.
