Epigallocatechin gallate, or EGCG, is the most abundant catechin found in tea, but it's only found in green tea, not black tea. It has proven anti-cancer as well as anti-carcinogenic effects. The only contraindication is if you're undergoing treatment for multiple myeloma and mantle cell lymphoma.
There's also evidence that it's effects are significantly anti-inflammatory, but without any of the negative side-effects of NSAIDs.
Pour boiling water over one bag in a coffee cup and let steep (and cool) for five minutes. Sip it well! About 1 cup a day will do you wonders.
PS: Coffee still has tremendous health benefits, including reduced risk of Alzheimers, dementia, parkinson's, improved cognitive function, analgesic, anti-diabetic, cancer, cardio, anti-oxidant, prevention of dental carries, gout, and blood pressure. In order to get these benefits, though, you have to stick to pure coffee. The flavored kinds contain all sorts of chemicals which do worse than the coffee does good.
Enjoy your day!
