Effect of oral administration of “Gadagi” tea on liver function and serum glucose concentration was assessed on thirty (30) healthy non – pregnant female albino rats. The animals were grouped and administered different doses (mg/kg) i.e. (low dose; 0.75mg/kg for “Sak,” 1.40mg/kg for “Sada” and 2.10mg/kg for “magani.” Standard dose; 1.50mg/kg for “Sak,” 2.80mg/kg for “Sada” and 4.20mg/kg for “magani.” High dose; 3.00mg/kg for “Sak,” 5.60mg/kg for “Sada” and 8.30mg/kg for “magani”) for a period of one week. Animals that were not administered the tea constituted the control group. At the end of one week, the animals were sacrificed and their serum alanine transaminase (ALT), aspartate transaminase (AST), alkaline phosphatase (ALP), bilirubin (total and direct) and glucose levels were determined. Mean serum glucose level of the control animals was significantly higher (p Keywords: “Gadagi” tea, Liver function, Toxicity , Serum glucose
