2. Green Tea (Chinese Tea / Camellia Sinensis)
First of all, in the case of green tea (also commonly known as Chinese tea), it is important to note that there is a big difference between brewing and then drinking tea made from the leaves of Camellia Sinensis as opposed to consuming an extract prepared from the dried leaves.
In the case of an extract, it is known to have high levels of Vitamin K which can interfere with and even work against the effects of some blood-thinning medications. Even when not on any medications, too much Vitamin K is not a good thing.
On the other hand, if the leaves are brewed to make a traditional green tea such as the kind which has been consumed in China and Japan for centuries, it has been shown to have a very low Vitamin K content. This is bad news for those who would rather take an extract, but good news for those who wouldn’t mind drinking a few mugs of tea per day.
