Considered by some a “superfruit,” as are noni and pomegranates, goji (also known as wolfberry) is a berry found on evergreen shrubs that grow primarily in the more temperate parts of Asia, such as China and the lower elevation of the Himalayas. Goji has a tart taste, and due to its appearance could easily be mistaken for a red raisin. Oddly, it is a member of the nightshade family, and therefore considered by botanists to be distantly related to the potato.
