Goji tea

Gugi-cha or goji tea is a traditional Chinese and Korean tea made from dried goji berries or leaves. Traditionally, the tea was made with young goji leaves. Today, mature leaves or, more commonly, berries are used. The tea made with berries may be called gugija-cha or goji berry tea, while the tea made with leaves is referred to as gugiyeop-cha  or goji leaf tea.

Preparation
Tea using berries is prepared with around 20-25 g of dried goji berries simmered in two cups of water, with various possible flavorings or sweeteners added. Leaf tea may be prepared with around 2-3 g of dried leaves infused in a cup of hot water.
