What is the special part of Sofeet Anti Bunions & Varicose Veins Health Sock? According to a report from the National Institutes of Health, tourmaline has been shown to be effective for most clinically severely podiatric patients in addition to surgery and diet programs. In a trial, we also found that this method was effective for 28 of 30 morbidly podiatric people (about 93%). Tourmaline is proven to have a therapeutic effect. It could help to promote blood and lymphatic circulation in the body for its high iron content. So, we know that if the blood circulation is poor, the cells in your body will not be able to get the nutrients and oxygen needed to thrive, leading to slow metabolism and toxin accumulation. Laboratory tests showed that the principle of negative ions and far infrared can help change the posture of the vessel wall membrane by circulating blood through the bottom of the foot, thus lowering the venous pressure and helping to normalize the venous valves in the legs. The lowered venous pressure heals varicose veins and various foot and leg problems such as swelling, lymphatic blockage and tissue edema. Tourmaline, working as the energy source, is attached to elastic fibers of this Sofeet Anti Bunions & Varicose Veins Health Sock and can produce power without electricity and other energy sources. There are a number of tourmaline points that can form an energy field, which can generate 100,000-300,000 energy units per hour. It helps to effectively stimulate the body's blood circulation, eliminate inflammatory cells and toxins, reduce body fluid accumulation and improve varicose veins and bunions.
