Why does drinking tea relieve migraine? Are there any professional experts?

Temper, anger and fear act on migraine caused by sympathetic nervous system, migraine caused by rapid contraction and relaxation of brain blood vessels, and blindness caused by compression of optic nerve by blood vessels or cranial nerves. This hospital is lying to you. No medicine can cure migraine. Drinking tea can make parasympathetic nerves play a leading role, so drinking tea has a little effect, but it is only a limited relief and cannot be cured.

If you want to recover, you must change your living habits, personality and mental activities, and heal yourself without taking medicine. But curing it is a complicated job, not as simple as taking painkillers. You need to be fully prepared for the changes in your life.
