Wolfberry, commercially called goji berry, is the common name for the fruit of two very closely related species: Lycium barbarum (Chinese: ????; pinyin: NÃngxiÃ gouqi) and L. chinense (Chinese: ??; pinyin: gouqi), two species of boxthorn in the family Solanaceae (which also includes the potato, tomato, eggplant, deadly nightshade, chili pepper, and tobacco). It is native to southeastern Europe and Asia. 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.
