Our marvelously brisk Peppermint comes from Oregon, and the leaves produce a wonderfully aromatic and crisp tasting tisane. We find a cup of Peppermint can also get a pesky stomach under control in no time. Caffeine-free herbal. Featured in our Historic Royal Palaces Collection in a brilliant green tin of 30 tea sachets. Each sachet brews a 12 oz cup of tea.
