Butterfly pea flower, also known as blue pea flower, is not considered a traditional "tea" in the sense that it does not come from the Camellia Sinensis plant, which is used to make traditional teas such as black, green, oolong and white tea. Blue pea is considered more of an herbal tea, which is made from the dried flowers of the "Clitoria Ternatea" plant commonly found in South-East Asia rather than the Camellia sinensis plant. Hence, it doesn't have any caffeine content and offers a different set of health benefits.
