Tisanes are often also called herbal teas. Tisanes do not contain leaves from the actual tea plant, so they don't have white tea, green tea, or black tea in the blend. Some of our blended tisanes have rooibos bases which are naturally caffeine free. In fact, the Very Berry and the Candy Apple make great gifts for teens and are both best sellers with our teen fans. Chamomile is another base that we use in our Chamomile Spa Blend, which is great for unwinding in the evening.
