The small, sweet fruits—known as goji berries, vitamin berries or wolfberries—are believed to improve eyesight and have been used to treat diabetes, circulatory problems and other health problems.
Goji berries are good for eating fresh or cooked. To dry them, spread the berries in a single layer on some paper and keep them in a cool, dry, dim location. Then use them dried or rehydrate them with a little water or fruit juice.
