It is well known that phyto-constituents possess hepatoprotective properties. The radical scavenging potential of catechin has received substantial research. The goal of the current study was to assess the beneficial effect of Catechin to safeguard rats from liver damage caused by isoniazid and rifampicin. In this investigation, Wistar rats were employed. Administration of isoniazid (100 mg/kg) with rifampicin (100 mg/kg) for 21 days caused hepatocellular injury. The dosages of catechin used were 25, 50, and 100 mg/kg body weight. Blood was drawn at the end of the study, and biochemical tests were performed to determine the enzyme levels. Restoration of AST, ALT, and ALP was brought about by catechin administration (25, 50, and 100 mg/kg body weight). The administration lead to in a restoration of the SOD and catalase levels. The expression of TNF-α, IL-1β, IL-6, MDA, and nitric oxide decreased. The findings prove that catechin had a significant hepatoprotective impact. The hepatoprotective action of catechin might be mediated by the radical scavenging and cytokine suppressing effects.
