What are those red itchy bumps under my eye?
I am afraid you have some infection there. Could be you were not washing your hands thouroughly before applying the green tea, or could be you are allergic to some preservatives there was on the tea bags to keep them fresh. Whatever it is, stop that method, and try to find the cause of your dark circles to put an end to it. A lot of people get dark circles by sitting up at night, or being on a certain diet, or staying too much in front of their laptops. Find some antiseptic eye cream, you can ask your pharmacist if he has small eye tubes of polymixin cream to use it on those bumps.
