Chinese Wolfberries (as dietary supplement) may improve vision imperfections caused by Type-2 diabetes..

Wolfberry, commercially called goji berry, is the common name for the  fruit of two very closely related species: Lycium barbarum. 


It is also known as Chinese wolfberry, mede berry, barbary matrimony vine, bocksdorn, Duke of Argyll's tea tree, Murali (in India), red medlar, or matrimony vine.  Unrelated to the plant's geographic origin, the names Tibetan goji and Himalayan goji are in common use in the health food market for products from this plant.

Marketing literature for wolfberry products including several "goji juices" suggest that wolfberry polysaccharides have extensive biological effects and health benefits, although none of these claims have been supported by peer-reviewed research.

Interestingly, now Dingbo "Daniel" Lin a researcher from Kansas State University, is studying wolfberries and their potential to improve damage to the retina. His findings show that the fruit can lower the oxidative stress that the eye undergoes as a result of type-2 diabetes.

Lin and his colleagues have found that wolfberries have high levels of zeaxanthin, lutein, polysaccharides and polyphenolics, which have been shown to improve vision, including the prevention of age-related macular degeneration and diabetic retinopathy. 

By using type-2 diabetic mice, the researchers are studying the effects of wolfberries on oxidative stress, one of the factors that occurs in diabetic retinopathy.
"I would not say that wolfberries are a medicine, but they can be used as a dietary supplement to traditional treatments to improve vision," Lin said. "Wolfberries have high antioxidant activity and are very beneficial to protect against oxidative stress caused by environmental stimuli and genetic mutations."
