Horse chestnut is the best-known natural
treatment for
varicose veins. It helps prevent swelling and strengthens capillary and
vein walls. The usual dose is 300 mg a day. Side effects are pretty rare, but if you start feeling itchy or nauseous, taper back your dose. Nature’s Way has a widely available, quality product I generally recommend.
Grape seed extract also supports the walls of blood vessels. Take 150 to 300 mg in divided doses over the course of a day.
