Just add it to the end of the boil or finished beer
But what would be the reason to ferment other than data

But you've got to boil or at least pasteurize the 'tea', and I'm way to lazy to take another step that wouldn't make much difference in the end. Mash capping? Sure, I'll do that with some grains that may impart harshness, like black patent. But no way would I boil it separately and then add it to the beer.
