I drink a lot of green tea and I'm going to go with no. I don't drink coffee though and I'm pretty sure coffee makes most peoples pain worse and that is why they recommend tea instead. I find that a good cup of green tea helps me relax a little and calm down. Unfortunately good green tea is hard to find without spending a fair amount. I find most green teas taste like dirt and I tend to buy the more expensive loose leaf teas to get the good ones. For a plain green tea I recommend sencha. For a little more flavor I buy genmatchia, it is really just sencha with roasted brown rice in it but it is so good, it's the one most Japanese restaurants use. I don't do fruity flavors in my tea but there are lots of those out there to choose from.
Teavana is where I shop. I know that in Edmonton Alberta Canada every mall has a specialty tea store. David's tea, Steeps tea, tea desire. If I'm not wanting to spend the money I sometimes go to the Asian grocery stores like T&T. Teavana is the best I have found but it is expensive. Mighty leaf teas are bagged tea that is available in some stores that is actually full leaf tea.
I drink teas as well. I drink loose leaf oolong to help with anxiety. Dr oz called oolong "natures xanax". Plus with a little stevia, I really like the flavor. As far as green tea, I understand that it may help to moderate inflammation and lower cholesterol. I also enjoy green tea with a little stevia. And always buy the organic.
Isn't tea a good antioxidant which helps with your immunity (getting sick). So I think it's more about supporting immunity for people in chronic pain as we tend to get sick more often than others. But I don't think it helps with the pain at all unfortunetly!
