why do we need to study chemistry

why do you take aspirin during a heart attack

Aspirin works on platelets by stopping their clotting action. Since blood clots can block the arteries that supply blood to your heart, the anti-clotting action of aspirin means blood can flow more easily while you seek further medical help to take care of the blockage.

Ginger has anti-nausea properties, keep that in mind. I know there are ginger pills and such you can buy for morning sickness, I never did though. Keep saltines handy, they work. Keep some by the bed and eat a few before bed and when you wake up. I also ate a lot of bananas. And drink milk, it's a filler and helps coat the stomach.
