Some European Physicians used mango tea (watery extract from
mango leaves) to treat not only diabetes but also blood vessel
problems and eye complaints related to this disease, They help
slow down the progress of diabetes angiopathy (disease of the
blood vessels due to diabetes). In fact, the definite improvement
observed in diabetes is due primarily to the healing influence of
these leafy compounds on the blood vessel in and around the
pancreas. Tea made from mango leaves is also good in the treatment
of diabetic retinopathy as well as hypertension. 1 cup each day
