This study assessed the probable effects of Ethanolic extract of Tanacetum parthenium (EETP) whole plant as hepatoprotective compound that acts on damaged liver due to administration of Sodium arsenite (NaAsO2 — 3mg/kg) in Wistar albino rats for a period of 28 days which results in alteration in Lipid peroxidation, antioxidant enzymes, biochemical factors, and liver enzyme. 30 animals were utilized for the study and are divided into five groups containing 6 rats each. Group –I treated as control received water, Group II-V were treated with sodium arsenite. Group-III received Vitamin-E (reference drug), Group IV treated with EETP 200 mg/kg dose and Group V treated with 400 mg/kg dose after hepatotoxicity induced by Sodium arsenite. Safeguarding effects of Ethanolic extract of Tanacetum parthenium whole plant were screened by analysis of the parameters like alanine transaminase, aspartate transaminase, alkaline phosphatase and total bilirubin, malondialdehyde, antioxidant enzymes. It was explored that administration of EETP at different doses could significantly decrease the enzymatic measures of AST, ALP, ALT, and TB concentration and increase catalase, GSH, GR and GPx levels in comparison with Sodium arsenite-induced control group. The data obtained from this experimental study prefigured the antioxidant potential of EETP and its potential hepatoprotective effects, and its beneficiary therapeutic effects on vandalization or disfigurement of liver due to Sodium arsenite induction in experimental animals.
