One of the many complications of diabetes can be Diabetic Retinopathy.  Caused by damage to the blood vessels in the retina of the eye, diabetic retinopathy impairs eyesight and can possibly lead to blindness. In a study performed by the Department of Pharmacology and Toxicology at the Medical College of Georgia, researchers studied the protective effects of cannabidiol (CBD) on rats with diabetic retinopathy.  CBD is one of the main components of hemp and has been shown to have a regulatory effect on the body’s endocannabinoid system, as well as, a diverse pharmacological profile.

During the conducted study, rats were induced with diabetes and treated with CBD after 1, 2 or 4 weeks. The diabetes caused significant rises in oxidative stress, retinal neuronal cell death and vascular permeability; following CBD treatment, these symptoms were reduced. The CBD administered also prevented retinal cell death and vascular hyperpermeability, which is excessive leaking of fluid and proteins from the blood vessels. The combined results demonstrated that CBD could reduce neurotoxicity, inflammation and blood-retinal barrier breakdown in diabetic animals.

We look forward to reviewing more medical studies regarding CBD therapy and diabetes.  To read the study from the Medical College of Georgia, referenced above, please see here.
