Chocolate is made from cocoa beans which are natural products. These beans contain flavanols, a biochemical which reduces the chances of formation of clots in the blood. A person who eats natural pure chocolate is at a lower risk of heart attack caused by blood clotting. According to medical research, the chances of blood clotting go down by about fifty percent. Blood clotting is caused due to thrombus formation which clots the blood vessels. Both aspirin and cocoa bean lower the formation of a clot. The comparative effect of aspirin is lower than chocolate.
