My cousin encountered severe headache because of her migraine.what is the best home remedies for this?

Caffeine : Regular tea usually has the most caffeine although coffee and some sodas have caffeine as well. Caffeine is only one ingredient that is in excedrine which is the best over the counter headache medication. It also contains tylenol (acetaminophen) and aspirine. Beware if you are taking prescription medication especially a blood thinner.
