Cinnamon has been used medicinally around the world. It’s used daily in many cultures, because of its widespread benefits. In fact, it’s one of the most popular herbs and spices in terms of its antioxidant levels. Antioxidants prevent oxidative stress from free radicals. Oxidative stress has been linked to many harmful effects on the body, including DNA damage and metabolic conditions such as diabetes, high cholesterol levels, atherosclerosis, heart disease, and obesity. Other conditions that may involve oxidative stress include cancer, high blood pressure, inflammatory conditions, cancer, Parkinson’s disease, and Alzheimer’s disease. Oxidative stress may also accelerate aging.
