So, if you actually just take a a bag of tea and weigh it in your hand, and you actually think about the third of the weight of that, that's all cancer fighting material.

The most potent one is actually called, of the cancer fighters is called EGCG or Epigallocatechin-3 gallate. It's a fancy latin word that actually identifies a molecule that not only kills cancer cells directly, but it can also cut off the blood supply that feed cancer cells, so it's a double barreled approach.

So many different teas are out there, but they all pretty much come from the same plant, the tea bush. How you dry it, how you ferment it, how you roast it can all make those subtle differences in the teas. We know that green teas, like plain raw green tea or oolong tea which is actually a type of green tea, those contain the highest concentrations of the cancer fighting flavonoid called EGCG compared to the black tea which is more fermented and often times roasted darker which still has the flavonoids, the cancer fighters, but to a lower amount.
