You may already be taking herbal supplements containing nattokinase to improve your circulation and help prevent varicose veins.

However, if your legs are already afflicted with the blue, spidery veins, you may be able to remove them without spending the night at a hospital, the latest Mayo Clinic newsletter claims.

Experts from the clinic say that patients have the option of destroying the veins themselves without interfering with blood flow by choosing from some treatments with high success rates.

For example, sclorotherapy involves the injection of smaller veins with a liquid or form that causes them to close off over the course of several treatments.

Meanwhile, lasers that give off fast and intense pulses of light can be moved across the legs, heating veins and closing them off.

According to the National Institutes of Health, varicose veins affect around 50 percent of people over the age of 50. They arise when valves that control blood flow in the veins cease to work properly, causing blood to pool and enlarge the veins.
