What are Goji Berries?

Goji berries are small bright red-orange fruits from the Lycium barbarum shrub. The plant is native to northern China and has been cultivated and used medicinally in China for over two millennia. In Traditional Chinese Medicine, goji is one of the most important tonics for the liver, kidneys, and eyes (the high zeaxanthin content is well-documented as supporting eye health). The berries gained substantial Western superfood marketing in the 2000s.
