Goji berry refers to the Chinese name for the bright orange-red fruit of the woody and thorny plant (shrub) Lycium babarum. In English, it is commonly known by the name wolfberry. L. barbarum is one of the 90 species of the genus Boxthorn (Lycium in latin) in the Solanaceae family (other plants in this family being tomato, potato, eggplant, chili pepper, tobacco, etc.). It is believed to have originated somewhere in the regions of southeast Europe and southwest Asia, but is now grown all over the world - China being the largest producer.
Goji berry is also known by other names like Chinese wolfberry, matrimony vine and Duke of Argyll's tea tree; in herbal health care stores the dried form of the fruit is marketed as Tibetan or Himalayan Goji berry. The majority of the commercially produced Goji berry comes from the Ningxia and Xinjiang regions in China.
