Picria fel-terrae extract has been investigated for its hepatoprotective activity. This current study was conducted to evaluate the subchronic toxic effect of
Picria fel-terrae Lour. leaf extract. The subchronic toxicity of ethanol extract of
P. fel-terrae leaf was evaluated by OECD (Organization for Economic Cooperation and Development) guidelines. The extract at doses of 125, 250, 500, 1000 mg/kg body weight (BW) were orally administered to the test animals for 90 days. Signs of toxicity and mortality were observed for 90 days and 118 days. The biochemistry, hematology, macropathology, relative organ weight and histopathology examination was also performed. The macroscopic and microscopic examinations of liver, lung, kidney, spleen and heart displayed normal color and texture after treatment, with ethanol extract
P. fel-terrae leaf at doses of 125 and 250 mg/kg BW. The signs of toxicity, mortality, macroscopic and microscopic changes, as well as increasing biochemistry parameters were observed after treatment, with extract at the dose of 500 and 1000 mg/kg BW. However, the abnormal value of biochemistry parameters was returned to normal when the treatment was stopped. There was no effect on hematological parameters at all doses of extract. The ethanol extract
P. fel-terrae leaf is untoxic for long-term use at dose 125 and 250 mg/kg BW. The toxic effect of
P. fel-terrae at 500 and 1000 mg/kg BW was reversible.
