Purple tea combines the health properties of green and black tea. Purple tea originates from the Camellia Sinensis plant, the same plant that we get our familiar black and green tea from. The purple appearance of the tea is caused by a unique genetic mutation which produces anthocyanin, the same powerful anti-oxidant found in blueberries. Purple tea has a pleasant, sweet and woodsy flavor. Purple tea has less caffeine than green tea but more than white tea.
