Answer to Question 1

Caffeine blocks the brain's receptors for the neurotransmitter or neuromodulator adenosine, which acts on the brain to produce behavioral sedation by inhibiting the release of other neurotransmitters. Blood vessels in the brain are constricted due to caffeine intake. This may be why it is good for headaches.

Answer to Question 2

Tea was the first popular caffeine drink in the U.S. Tea taxes led to the Boston Tea Party, a rejection of tea shipments that helped lead up to the revolution. Americans then began to drink more coffee and less tea. The English drank more tea as a show of support for the crown.
