In view of suggested anti diabetic potential, effect of aqueous and cold extracts of
Terminalia Catappa
Linn (Combretaceae) leaves, on fasting blood sugar levels and serum biochemical analysis in alloxaninduced diabetic rats was investigated. All the extracts of
Terminalia Catappa produced a significant anti diabetic activity at dose levels of 1/5
th of their lethal doses. Concurrent histological studies of the pancreas of these animals showed regeneration by aqueous and cold extracts which were earlier necrosed by alloxan.
