Black tea is the most popular tea in the world. It is the tea most widely used in making iced tea and English tea. During the fermented process, black tea formed more active ingredients and theaflavins. They contain high amounts of Vitamin C, along with calcium, potassium, magnesium, iron, zinc, sodium, copper, manganese, and fluoride. They also have more anti-oxidants than green tea, and are anti-viral, anti-spasmodic and anti-allergic. In addition to all of these health benefits, black teas are also less astringent and have a mellower flavor than green or black teas.
