Black tea is from the same shrub as oolong, green, and white teas in the Camellia sinensis. However, black tea is the least oxidized and the strongest in flavor, out of the four kinds of teas. Black tea is one of the most popular drinks in the Western world. Luckily, there are many health benefits.
