Abstract Background: The broad development of the chemical industry, the use of pesticides in agriculture has led to an increase in hepatitis. At the same time, different substances in their structure can cause liver function failure. Objective: The objective of this work was to assess the functional state of the liver of animals poisoned with the pesticide Bagira, using in their diet dishes made from local food and additional introduction of a complex of local herbal medicines into the diet. Methods: The study involved patients with toxic hepatitis who had industrial contact with chemicals. The total number of patients was 80 males, aged 35 to 78 years. Results (Findings): Based on the results of our research, the antioxidant phyto tea helps to eliminate cytolytic, cholestatic, inflammatory syndrome, improve the protein-synthetic function of the liver, improve the functional activity of the liver, remove toxins from the body, maintain the function of organs and systems. It is a natural, safe, powerful antioxidant. Conclusions: 1) Studies have shown that patients diagnosed with chronic hepatitis have disorders of the functional state of the liver, as well as the gastrointestinal and nervous systems. 2) Change of biochemical indicators indicates a violation of metabolic, proteinsynthetic, biliary, antitoxic functions of the liver: increase of bilirubin fractions, the activity of alanine transferase (ALT), AST, the level of alkaline phosphatase, gamma-glutaminetranspeptidase (GGT) in serum. 3. The use of phyto tea "Antioxidant" in patients with toxic liver damage contributed to the increase of liver functional activity.
