Biochemical studies on hypoglycemic effect of Aavirai kudineer: a herbal formulation in alloxan diabetic rats.

ABSTRACT

Aavirai Kudineer (AK) is an herbal decoction of seven botanical drugs, cited in the Gunapadam; a Tamil Siddha medical text. The anti-diabetic efficacy of this formulation was evaluated using alloxan-induced diabetic and normal rats. Glucose tolerance was observed within 1 hr in AK-treated rats (10 ml/kg body ) as compared to control. A significant decrease in the severe hyperglycemia characteristic of alloxan diabetes was noted after 15 days of AK treatment. Further AK treatment reversed the elevated urea, creatinine, cholesterol and decreased protein values to near normal levels. Assay of glycogen content and chief carbohydrate-metabolizing enzymes, viz. hexokinase, glucose-6-phosphatase and fructose 1,6 diphosphatase in the liver of diabetic and AK-treated diabetic rats clearly ascertains the hypoglycemic efficacy of this formulation. The mode of action of this herbal formulation remains to be elucidated.
