Tisane is originally a French word, which is used for any warm herbal drink. (Although today, they may also come in an iced form). In English, it carries much the same meaning, of "herbal teas." Many of these can be grown at home then dried and consumed, including chamomile, lemon balm and citrus bergamot (which has an Earl Grey flavor). One advantage, or disadvantage, of tisanes over normal tea is that they are caffeine-free, making a perfect night cap before bed. In the late 1990's and early 21st century, many of these "teas" were sold for minor mood altering characteristics, some with basis, some without. Regardless, most have been used for centuries as a sort of folk medicine. Tisanes may be a good choice for the politically active, especially in communities where fair trade tea and coffee are not widely available.
