* [[Astragalus]] is considered to be a cardiac tonic. In the cardiovascular system, the saponins in astragalus inhibit lipid peroxidation in the myocardium and one study using patients with angina revealed that cardiac output increased after two weeks of treatment. Astragalus strengthens left ventricular function and reduces free radical damage in patients after a heart attack and increases super oxide dismutase activity in cardiac muscle.
* [[Rutin]] is proved to be a very potently anti-thrombotic compound.
* [[Folic Acid]] supplementation improves arterial elasticity to lower heart attack risk.
