Gotu kola supports and strengthens veins by multiple mechanisms:
With insufficient strength to return blood to the heart, weakened veins can develop venous hypertensive microangiopathy (VHM). Although it is not considered a risk factor for coronary disease like arterial high blood pressure, VHM can lead to varicose veins, edema, and even leg ulcers.37 A number of human studies show that gotu kola can significantly improve these symptoms, including a randomized, controlled clinical trial that demonstrated significant improvement in VHM and no negative side effects with doses as high as 120 mg/day.17,24
