The Beatles got it wrong. All you need is peppermint! That's literally the only thing we put in this tea. That's how we created the best possible peppermint herbal tea! By using only the best peppermint. Stash Tea became the first adopters of Pacific Northwest peppermint when we discovered that the peppermint grown right here in our backyard was the world's finest. Now, over 40 years later, this simple ingredient still makes our peppermint tea one of the best herbal teas out there.
