Herbal Tea for Picky Eaters

My kids are great at trying new foods, and usually enjoy my homemade concoctions. I have one boy, however, who just can't learn to like tea. "It tastes like bathwater!" he tells me. So while the rest of us are sipping warm cups of echinacea tea to stave off the sniffles, he won't touch it.
Finally I figured out the trick - I steep the tea bags in apple juice, and now he'll drink it! I don't need to add any honey or other sweeteners, because the apple juice is naturally sweet enough. While I don't usually let my kids drink fruit juices (I prefer that they eat whole fruits), for the sake of getting that immune-boosting goodness into them, I'll give them that treat.
