The cinnamon Cinnamomun verum J.Presl is an evergreen tree from Sri Lanka. Various properties have been attributed to it, one of them being the reduction of the glucose level, therefore the objective of this work was to evaluate the hypoglycemic effect of cinnamon Cinnamomun verum J.Presl, which grows in the Huyro district (Convention Province, Cusco-Peru) at an altitude of 1524 masl. Cinnamon was collected (leaves, fruit and stem), its taxonomic classification was carried out and with the collected samples the aqueous extract was used that was used to perform the phytochemical screening, bromatological analysis and to evaluate the hypoglycemic activity (in concentrations 60 mg/kg, 100 mg/kg and 150 mg/kg) in rats induced by hyperglycemia with streptozocin. A significant decrease in blood glucose level was observed in rats treated with the aqueous cinnamon extract.
