It is known in China that green tea helps lower blood pressure. But it often take years to see the result. However I often ran into customers saying that after taking Tai Chi Green Tea, their blood pressure lowered.
The study finds that green tea does not affect blood pressure in short run. But why people see blood pressure lowered?
I found most people who claimed that their blood pressure lowered down after taking green tea also found that they lost a lot of weight or some other health problems of theirs are gone --joint pain is gone, lungs cleaned and etc. Most likely it is because green tea helped them to get rid of some of the problems that caused their high blood pressure, once the problems are gone, their blood pressure got normal.
