However, the potential of olive leaf treatments in reducing diabetic complications, the possible contribution of the Ang II, as a central target for the anti-diabetic potential of olive, where the treatment of diabetic group with OLE in the present study showed decrease in Ang II content in the kidney tissue, could be attributed to the oleuropein which is the key hypotensive component of OLE due to L-type Ca 2+ channel antagonistic effects (Scheffler, Rauwald, Kampa, Mann, Mohr, et al, 2008).
