Goji berries or wolfberries are berry fruits harvested from the Lycium barbarum tree. The tree grows up to 3 meters in height, produces a distinct berry (goji berries), and can be found natively in southeastern Europe and Asia. Goji berries are of interest nutritionally because they are a rich source of nutrients, particularly antioxidant polyphenols. However, there are other health providing nutrients within the berries and one such nutrient are a group of polysaccharides called Lycium barbarum polysaccharides (LBP). Studies suggest that Lycium barbarum polysaccharides are bioactive, and may have a number of health effects including liver function protection, anti-radiation effects, anti-fatigue effects, anti-tumor effects, as well as acting as antioxidants. Evidence suggests the Lycium barbarum polysaccharides are protective of mental health following the application of stress. This protective effect may result in improvements to memory and provide significant neuroprotective effects that protect the brain from injury.
One of the areas of the brain most affected by stress is the hippocampus. Under stressful conditions there is evidence that neurones in the hippocampus degenerate and this leads to cognitive decline and depressed mood in both humans and animals. Lycium barbarum polysaccharides from goji berries may protect the neurones in the hippocampus from this damage, and thus can prevent the cognitive and mood deficits seen with exposure to stress.
