I wish I wasn’t drinking this, because when I break this box out, it means I feel pretty lousy. I have noticed that this herbal remedy does make me feel a bit more energetic when I am down, but I have never drunk enough of it to assess whether it shortens the duration of a cold. I will note that I have failed to get ill quite a few times when I thought I was going to, after treating myself with a few bags of this tea. Tastes a bit green and a bit minty, like a slightly odd mint tea. Good job hiding the taste of echinacea! Doesn’t quite make the ’I’d drink it for the flavor’ list, but it’s not bad at all.
