It is difficult to analyze such a case with such a brief description, and even difficult to say that tea is the cause even if it seems to be so. Could you please specify if it was a green or browned Tie Guan Yin, how did you brewed it and how much did you drink it? Did you have headache soon after drinking that tea or much later on? And for how long? Have you eaten something after having tea? Finally, do you normally suffer from headache? If so, in which conditions?
