This preclinical study tested purple sweet potato leaf (PSPL) extract on diabetic rats to see if it could improve diabetic retinopathy. The extract, especially at 400 mg/kg, successfully reduced markers of diabetes and protected the retina and other organs from damage.
This study evaluated the effect of lutein-rich purple sweet potato leaf (PSPL) extract on diabetic retinopathy (DR) in streptozotocin-induced diabetic Sprague-Dawley rats over 12 weeks. The 400 mg/kg dose also showed protective effects on kidney, liver, retina, and pancreas histology, reduced retinal inflammation (IL-17A), and prevented cataract formation. The study concludes that 400 mg/kg PSPL extract ameliorates DR pathology in this animal model. Limitations include the use of an animal model, which may not directly translate to humans, and the 12-week duration which may not capture long-term effects.
