Cardiovascular diseases are a group of conditions that involve the heart or blood vessels. They are the number one cause of death globally, taking an estimated 17.9 million lives each year. A number of plants are proven to have a general positive effect on the cardiovascular system. Adding specific herbs and spices to your diet can lower the risk of a heart attack or stroke by reducing the production of plaque that may clog the arteries. Especially a spicy diet including chilli peppers or garlic can lower the blood pressure and boost your heart health.
