Lycium (Lycium barbarum).

The berries of Lycium barbarum, a perennial plant native to Asia and southeastern Europe, have been used for centuries in traditional Chinese medicine to treat poor vision, anemia, inflammation, and cough. They are also consumed as food and used in soup recipes. Lycium has gained immense popularity in the United States over the past decade because of its antioxidant properties. It is available in health food stores and is marketed via the Internet in juice form, typically blended with the juices of other berries and fruits. A wide range of health benefits, including cancer prevention and treatment, have been claimed for lycium.
