Goji

background

The origin of goji berries is unknown. Goji berries have been used as food and medicine for over 2,000 years in Asia. The common name, "wolfberry," is often used in science. There is some controversy as to whether goji and wolfberry are the same fruit. Most experts agree that they are similar, but not identical because they are grown in different parts of Asia. However, the health-food industry has adopted the name, "goji," which may come from the Mandarin name, "gouqi."
The leaves, roots, and root bark have been used as medicine. Goji berries have been used for kidney, liver, and eye health. They have also been used for immune enhancement, male infertility, and anti-aging purposes. Goji berries are rich in nutrients such as lutein and zeaxanthin. Goji berry is being studied for eye diseases, such as macular degeneration, vision loss with age.
Data is still limited, but there is a growing body of research on goji. Some compounds in goji berries have been studied for possible anticancer, antidiabetic, blood pressure-lowering, anti-infertility, antioxidant, cholesterol-lowering, and immune-stimulating effects.
