"Tisane" is the French word for "herbal infusion". It is not tea and has no true element of tea. It is a decoction of herbs, spices, and other plant parts blended to create an aromatic and flavorful extract that is mostly caffeine free. Yet, somehow, it fits perfectly into the category of tea and is quite popular with tea lovers. It is a health drink with surprising benefits, such as diuretic qualities and as a stress reliever.
