Cinnamon
Cinnamon has been dubbed, by many, as the most delicious spice in the world. Beyond its flavor, studies suggest that it has the ability to cause short-term reductions in one’s systolic blood pressure (pressure in the arteries when the heart beats). In addition to its short-term effects on hypertension, it also lowers blood sugar levels, reduces certain risk factors for heart disease and has anti-inflammatory properties. But be careful with this spice, since too much of one thing is never a good idea. Ingesting too much cinnamon could have adverse effects on the liver. Experts recommend no more than one teaspoon a day.
