Gugi-cha (구기차; 枸杞茶) or goji tea is a traditional chinese/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 (구기자차; 枸杞子茶) or goji berry tea, while the tea made with leaves is referred to as gugiyeop-cha (구기엽차; 枸杞葉茶) or goji leaf tea.
