Here is an article by Dr. Andrew Weil, the Founder and director of the Arizona Center for Integrative Medicine published at the Huffington Post:
I have written about the health benefits of green tea for more than 30 years, and it is possible that in some very small way I have helped this wonderful beverage become popular in the United States. I hope so, because today, thousands of scientific studies confirm what the ancient Chinese knew through simple observation: green tea is perhaps the most healthful beverage human beings can consume. Studies either strongly suggest or confirm that the antioxidants in green tea can reduce LDL cholesterol, promote fat burning, reduce the risk of several forms of cancer and alleviate depression.
But tea is much more than the healthful compounds in it. It is an experience, and for me, a personal story of discovery that continues to this day.
Drinking a daily cup of tea will surely starve the apothecary.
