Hypoglycaemic effects of Andrographis paniculata Nees on non-diabetic rabbits

So far known Andrographis paniculata Nees (AP) is a hepatoprotective, antiplatelet and antithrombotic drug. In this experiment its hypoglycaemic effect has been tried in various way. Water extract of AP 10 mg/kg body weight can prevent induction of hyperglycaemia significantly (P < 0.001) induced by oral administration of glucose 2 mg/kg body weight. But any how failed to do so in adrenaline induced hyperglycaemia. It also failed to demonstrate any "fasting blood sugar lowering effect" upon chronic administration (6 weeks) of AP. So probably AP prevents glucose absorption from gut. Whole experiment was done on rabbits.
