Facts about Green Tea


All real tea is from one plant. Herbal tea is not real tea. Real tea is made from the leaves of the shrub (or small tree) Camellia sinensis. Black, oolong, green, yellow, and white teas are all from Camellia sinensis.


Green tea is a non-fermented tea. Or in plain language, green tea is not allowed to discolor from rotting for taste reasons as are black teas. Old and fermented teas can lose most of their health benefits from losing their nutrients through oxidation.


The main difference between black, oolong, green, and white teas is the degree of oxidation that is allowed to take place. Black gets more oxidation than oolong which gets more oxidation than green. Many other factors also go into categorizing and naming teas.

Composition of unfermented Camellia Sinensis or Green Tea:

Epigallocatechin gallate or EGCG is the most abundant catechin in green tea. It is not found in black teas, because black teas are processed teas.
