Tisanes are infusions. The word Tisane comes from France and in ancient times, it originated as a medicinal drink that was chiefly barley water. Over time, it has evolved. Common herbal infusions are, of course, with Mint and other herbs such as Chamomile or Lemongrass. You may also have tried infusing Cinnamon, Ginger Root or Lemon Verbena. Tisanes are not Teas although the term ‘herbal tea’ is now synonymously used for herbal blends, fruit tisanes, rooibos and decaffeinated teas. An astute tea vendor will probe further when a customer walks in and asks for Herbal Tea.
