What is Green Tea? Green tea, also known as unoxidized tea, is made solely from the leaves of the camellia sinensis plant. The leaves are plucked, slightly withered, then immediately cooked to preserve the green quality and prevent oxidization. As a result of these methods, green teas have a much higher concentration of chlorophyll, polyphenols and antioxidants than other tea types. The growing conditions for green tea can be broken down between two different types: sun grown and shade grown.
