For those of you who have had trouble with green tea, read on! Here's another blog post that explains a potential reason. Thanks a bunch to Morning Coffee and Afternoon Tea for sharing this!
I tend to be of a fiery personality (Aries and tending toward Yang). I also am choosing green teas more and more frequently. On any given day, there's a 70% chance I'll be drinking a green (or a "soft" oolong). So, this is good news for me - my body has wisely chosen a tea for me. I do tend to drink black tea more in the winter, which would be appropriate to add more "fire."
