Goji berry fruit is bright orange-red and ellipsoid in shape. It is produced by a deciduous woody perennial plant that grows up to 3 meters high. Found inside goji berries are 10-60 tiny yellow seeds.

Goji berries have both culinary and medicinal uses. Dried goji berries are added to rice congee, almond jelly, soups, and in combination with pork or chicken, vegetables, and other herbs like licorice, wild yam, and astragalus. They are also boiled to make herbal tea, usually in combination with other traditional Chinese herbs. They can be fermented to make wine.

Goji berries have many uses in Traditional Chinese medicine. It is believed that eating goji berries prolongs life, enhance fertility, and promote general well-being.

Goji Berry as Great Source of Antioxidants

The antioxidants found in goji berry are Vitamin C, lycopene, lutein, beta-carotene, zeaxanthin, cryptoxanthin, and xanthophylls. These antioxidants protect the body from free radical damage. Free radicals are reactive compounds that damages cells and DNA, causing cancer, premature aging, heart disease, neurodegenerative disorders, and metabolic diseases.

Carotenoids like beta-carotene, lutein, and zeaxanthin have been shown to protect the eye retina by absorbing blue light and by acting as antioxidant. Studies show that increased intake of fruits and vegetables high in carotenoids like goji berry may decrease the risk of developing age-related macular degeneration, the major cause of vision loss and blindness in people over the age of 65.
