Effect of garlic (Allium sativum) oil on exercise tolerance in patients with coronary artery disease

The effect of six weeks garlic oil administration was observed on cardiac performance and exercise tolerance in 30 patients of coronary artery disease. After initial treadmill stress test, they were administered garlic oil in the dose of four capsules twice a day for 6 weeks and treadmill stress test was repeated. Garlic significantly (P<0.01) reduced heart rate at peak exercise and also significantly reduced the work load upon the heart resulting in better exercise tolerance (P<0.05) as compared to the initial test. It appears to be a good adaptogen to be utilized in patients with coronary artery disease.
