The goal of Ayurvedic medicine is to prevent diseases. Studies have suggested that Ayurveda may be effective at reducing the risk of heart disease. For example, one study found that Ayurveda helped reduce plaque and reverse the thickening of artery walls known as atherosclerosis in both healthy adults, as well as adults at high risk for heart disease. Atherosclerosis is a slow, complex disease in which cholesterol, fats, and other substances build up in the inner lining of an artery. This buildup, known as plaque, can lead to heart attack and stroke.
