What is tea ?

There is a separate category for herbal blends and fruit infusions, which are more properly characterized as tisanes. A tisane refers to a caffeine-free blend consisting of herbs, botanicals and/or fruits prepared like a tea, but technically not a tea. If the drink does not have tea leaves from Camellia Sinensis, it is not a tea. It is most likely a tisane. Therefore, it would be an oxymoron to call something an herbal tea because it can only be one or the other.
