Goji berries (Lycium barbarum) are the most nutritionally dense fruit on Earth. They are a member of the nightshade family (Solonaceae), which contains many other common vegetables such as potato, sweet potato, tomato, eggplant, and pepper, as well as some poisonous plants like belladonna and deadly nightshade. Native to the Himalayan Mountains of Tibet and Mongolia, the goji berry is now grown in many other countries as well. Although they have only been introduced in Western countries in recent years, gojis have been used for thousands of years in Tibet and China, both as a culinary ingredient and medicinally. Unique among fruits because they contain all essential amino acids, goji berries also have the highest concentration of protein of any fruit. They are also loaded with vitamin C, contain more carotenoids than any other food, have twenty-one trace minerals, and are high in fiber. Boasting 15 times the amount of iron found in spinach, as well as calcium, zinc, selenium and many other important trace minerals, there is no doubt that the humble goji berry is a nutritional powerhouse. This amazing little superfruit also contains natural anti-inflammatory, anti-bacterial and anti-fungal compounds. Their powerful antioxidant properties and polysaccharides help to boost the immune system. It's no wonder then, that in traditional Chinese medicine they are renowned for increasing strength and longevity. There are several variations of goji tea. The traditional version does not use any tea. Instead, you drop the goji berries into boiling water. You then drink the boiling water and eat the berries in the beverage. Newer versions of goji tea infuse the goji berries with white or green tea. Green and white teas have antioxidant properties, so combining these teas with the goji berries increases the antioxidant properties of the beverage.
