Hepatic damage was assessed using a composite score assigned to histopathological findings of degeneration, necrosis and fibrosis. The antituberculosis treatment (ATT), when given for 90 days, induced significant degeneration and necrosis (score: 7.5; <jats:italic>p<\/jats:italic> &lt; 0.01 vs vehicle) associated with morphological changes. However, no change was found in the serum bilirubin and liver enzymes. Co\u2010administration of silymarin (positive control, 50 mg\/kg) with ATT protected against necrosis (score: 1.5; <jats:italic>p<\/jats:italic> &lt; 0.001 vs ATT). <jats:italic>Tc<\/jats:italic> (100 mg\/kg) showed a reduction in liver damage (score: 6.5), which was not statistically significant. On the other hand, <jats:italic>Pe<\/jats:italic> (300 mg\/kg) prevented the necrotic changes to a significant extent (grade: 100; <jats:italic>p<\/jats:italic> &lt; 0.05 vs ATT; score: 5.5). Combination of <jats:italic>Tc<\/jats:italic> and <jats:italic>Pe<\/jats:italic> in their therapeutic doses (1:3) significantly prevented the necrosis (score: 3.5; <jats:italic>p<\/jats:italic> &lt; 0.001 vs ATT). Similar effects were seen even when the doses were halved and were comparable to the silymarin group. Thus, this study proves the synergistic protective effects exerted by the combination of <jats:italic>Tc<\/jats:italic> and<jats:italic> Pe<\/jats:italic> when co\u2010administered with ATT.
