A varicose vein is a sign of blood thickening and possible blood clot, and a blood clot is potentially dangerous, obstructing the heart, and we call it heart disease, obstructing the brain and we call stroke, obstructing the legs and we called it varicose veins. There is a much simpler disease that describes all three condition: blood clot. Scientist prefer to call them platelets aggregation. Now if we continue to use highly specialized words, we won't ever know the real cause of the condition. For doubting Thomas, is best to get a live blood analysis and just look at all the blood platelets clumping together. Vitamin E, and blood thinners such as aspirin may also help, but my findings is blood clot is influenced by bacteria (pathogens), excessive protein (leadng to blood thickness), metabolic acidosis (acid blood precipitates, and hence clots), heavy metals (free radicals) and of course, excessive calcium which accelerates blood clotting, leading to a major circulatory problems, and that leads to lower oxygen, and hence lower immune system. Blood circulation and oxygen is everything. People can't see we are strangulating ourselves quietly whenever blood clots forming varicose veins, and if they become large enough, and clots in the leg, those clots may travel to the brain causing stroke, to the heart causing heart disease, and they are all the same condtion.Theefore, I believe it is important to monitor the condition of our blood circulation. It's as important as oxygen. Just think of it this way: if blood circulation is constantly obstructed, then blood reaching the heart is limited. When this happens, it's no surprise that a heart can't beat without normal circulation to the heart muscles reaching it. Magnesium also helps heart muscles to relax so that it can beat more normal. Excess calcium causes heart to contract but can't release itself, while magnesium helps in relaxing and thus enable circulation to normalized. Therefore magnesium supplements, such as 500 mg may help too for heart condition.
