Goji berries (wolf berries, lycii berries) are nutritious, and they are rich in immune stimulating polysaccharides. They also support the eyes, liver, kidneys.
My only complaint is that the MLM companies are once again taking a common and inexpensive product and over inflating the price and adding a lot of hype to justify their higher costs. Goji berries are nothing more than the common lycii berry found in any Chinese market for about $5.00 a pound. Better than the $45.00 a pound the MLM companies are charging.
