When you think of tea, what do you think? Green? Black? Oolong? Some people think of herbal. I have several herbal teas, myself. But herbal teas are not actually tea.
Herbal teas are usually a blend of herbs, spices, flowers, roots, and fruits, and for all of you Hercule Poirot fans, they are more accurately called tisanes. Most studies done on tea do not include herbal concoctions. Another tea that has become quite popular is rooibos, sometimes called red tea. It, too, is an herbal drink and not a real tea. Herbal teas by their very nature are caffeine free. Sometimes an herbal may be mixed with a true tea, so read labels carefully if you are trying to reduce or eliminate caffeine.
Rooibos with turmeric, cinnamon, and vanilla. The mug is a gift from a good friend.
