Green tea is the unfermented leaf of the Camellia sinensis plant. The leaves are dried right after picking and researchers believe that it has more powerful antioxidant activity because it is less processed (fermented) than black tea. The American Journal of Cardiology reported in 2002 that participants in a Japanese study who drank at least one cup of green tea per day were 42 percent less likely to suffer heart attacks than those who did not. Heart disease is less common in Japan than in the West, and heavy consumption of green tea may explain why.
Experts recommend you brew green tea in a pot that allows expansion of the leaves, use hot water that is just below boiling temperature, and steep the tea for two minutes.
