Green teas come from the same plant as black, oolong, and white teas, the camellia sinensis. The leaves for green tea are
non-fermented or unoxidized. Green tea has been consumed in China for centuries, however, in the western world it has been gaining in popularity because of recent research on its antioxidant properties. 

One rule for green teas is to never use boiling water. It is just too hot for the delicate leaf.

This will almost always ensure a decent cup of tea. To make green teas, use 1 teaspoon of tea per cup.

Pour not-quite-boiling water over the tea and let steep 2-3 minutes. Many teas may be steeped multiple times.
