Evaluating the Hepatoprotective Effect of Phyllanthus emblica and Panax ginseng Powders on Acetaminophen-Induced Liver Fibrosis in a Rat Model.

Liver fibrosis is a progressive disorder, that originates from prolonged and persistent acetaminophen (APAP) exposure, a commonly used antipyretic and analgesic drug. If left untreated, fibrosis may lead to cirrhosis or hepatocellular carcinoma. Phyllanthus emblica L. and Panax ginseng C.A. Meyer possess hepatoprotective, antioxidant, and immunomodulatory properties. The aim of this study is to evaluate the individual and combined effects of P. emblica fruit and P. ginseng root powders against APAP induced liver fibrosis in a rat model. A 38-day study trial was conducted using 20 male Wistar rats, which were divided into five groups, each group containing four rats. Hepatotoxic doses of APAP were administered for 10 days to induce early-stage liver fibrosis in rats. A negative control group (G0) on normal diet without liver fibrosis, a positive control group with liver fibrosis on a normal diet (G1), and treatment groups (G2, G3, G4) receiving varying doses of P. emblica and P. ginseng were evaluated for liver function tests (alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase, gamma glutamyl transferase, total bilirubin, albumin), oxidative stress biomarkers (glutathione), hematological indices and histopathological analysis. Results demonstrated that combination treatment G4 significantly improved liver function biomarkers, and normalized hematological parameters. However, P. emblica restored glutathione levels most effectively among all treatments. Histological examination revealed a marked reduction in necrosis and fibrosis. This study concluded that combined activity of bioactive components of P. emblica (vitamin C, ellagic acid, gallic acid) and P. ginseng (ginsenosides) significantly attenuated APAP-induced hepatic damage and fibrosis, underscoring their potential role as complementary therapeutic options for drug-induced liver disorders and halting fibrotic advancement.
