Green tea

„A book written in the Tang Dynasty of China is considered one of the most important in the history of green tea. The book was written by Lu Yu and is called the "Tea Classic" or "Cha Jing". It was written between 600 and 900 AD and spoke about exactly how and where one could enjoy a fine cup of green tea.“

„A 2012 systematic review concluded the evidence that green tea can prevent cancer "is inadequate and inconclusive" but with some evidence for a reduction in certain types of cancer (breast, prostate, ovarian and endometrial).“
