3 kinds of tea

From The Twelve Teas of FriendshipThere are really only three kinds of tea- Robust Black Tea, made from leaves that have been allowed to ferment; delicate Green teas, which are steamed instead of fermented; and in-between oolong teas, which are only partially fermented.  Any of these three basic varieties can be blended, scented, or flavored with fruit, flowers or herbs.  But a true "Herbal Tea" is not really a tea at all because it contains no tea leaves.
