First and foremost, no one here can say green tea is or is not "against the word of wisdom". It is not written in black and white in any of the standard works, or in and modern day revelation. If you can find it, I would love to see it.
This is one of those " it's up to you" topics.
We have been told "coffee and tea" are not allowed. Those are in black and white. But herbal teas are not prohibited, and you can find that in several places at lds.org. I have heard people say if you boil a stick in a cup of water than you had made tea and it is Against The Word of Wisdom. However by using that mentality, I could not eat soup if I have put in oregano or parsley. So I guess soup is out of the question now?
Anyway seriously, green tea differs from black tea by its preparation after it is picked. Black tea goes through a fermentation process prior to drying which creates additional chemicals that are not found in green tea. Green tea is dried immediately after picking so the additional chemicals are not produced. It is a fallacy and reasoning to say that because green tea and black tea come from the same plant, then they are the same thing. I enjoy bread. Bread is made from wheat and yeast and sugar. However you can also take wheat and yeast and sugar and make liquor. It goes gone through a fermentation process which creates additional chemicals such as alcohol, that are not allowed by the word of wisdom. So one could argue that green tea is okay because it has not gone through theb fermentation process, just like you could argue that wheat is okay because it has not been fermented.
