What Is Tisane?
Also known as herbal teas, tisanes (pronounced ti-zahn) are not actually teas at all (i.e., they do not come from the
Camelia Sinensis plant). Instead they are infusions made from leaves, bark, roots, berries, seeds, and spices. Common tisanes include mint, chamomile, verbena, and rooibos.
