There are basically 3 types of teas (black, oolong and green) and they are all derived from the same source – they are produced from the leaves of the Camellia Sinensis plant.
The difference only lies on how they are produced (the level of oxidation/fermentation). Black tea is fully fermented (thus the strong dark color), oolong is partly fermented, while green tea is unfermented.
It is important to note that the more oxidized or fermented the tea is, the higher the caffeine level and the lower the anti-oxidant content (the main source of its health benefits).
