Results of the present investigation strongly suggest an antidiabetic
potential for aloe. In-vivo results show decreased serum glucose and increased serum insulin levels in aloe-treated rats
compared to diabetic controls (Table 1). In agreement, previous
authors claimed for such antidiabetic effect for aloe extract
on experimental animals.18,19 Our in vitro results support this
finding, where aloe was found to increase the rate of insulin
secretion from pancreatic islets (Figs. 4 and 5).
