ABSTRACT

Bidens pilosa L. is a medicinal plant popularly used for treatment of liver diseases. In this study, the dry extract of aerial parts of Bidens pilosa and Silymarin, a phytocomplex obtained from the Silybum marianum fruits and marketed as hepatoprotective, were tested in dogs experimentally acutely intoxicated with carbon tetrachloride. The liver activity was evaluated by hematological and biochemical profiles, and histological and ultrasound analyzes. It was observed that the lowest serum activities of ALT and serum concentrations of total bilirubin occurred in the groups treated with the dry extract of Bidens pilosa, while only decreased serum concentrations of total bilirubin occurred in the group treated with Silymarin. Best liver recovery was also observed for the dry extract of B. pilosa at a 400mg/Kg dose by ultrasonography. This study showed that the dry extract of Bidens pilosa acted more efficiently in the treatment of acute toxic hepatitis induced in dogs than Silymarin.
