Just a little tip: Just Food has their Yogi Tea on sale right now, 2/$6. I always stock up on tea during this sale as I like their blends - no artificial ingredients or flavorings.
And they use mullein leaf in their respiratory support blends, the only brand I have found that adds this when I checked a few years back. And if you've taken any classes from me dealing with herbs for lung support, you know I love my mullein for tea!
There are several other varieties of tea I also like, but Yogi does seem to offer good sales more often, which I appreciate.
