What is an herbal Tea?

Herbal teas, or tisanes, are infusions made of various plants or shrubs, excluding Camellia sinensis tea plant. Fruits, flowers, leaves and spices may be infused as they are, or blended in aromatic mixtures. Besides the delicacy of their aroma, herbal teas are caffeine free (except for Yerba Mate, considered as a stimulating beverage). Tisanes and herbs are also often referred to as medicinal plants, known for their health benefits.
