Look up iodine and IP6 and their ability to cleanse the blood, gently, of plaque. There is A LOT of research that shows that arteriosclerosis, clogged veins and the like are actually caused by calcification and the wrong forms of macro minerals (from tap water, etc) collecting in the veins and inhibiting circulation and oxygen transport. Are you on iodine? I've been on iodine for six months and my circulation is sooooo much better!
IP6 rocks. It's a little tricky to dose with but once you get the hang of it - you'll love it. Look for Newport and Vulcanel's posts on IP6 and calcification!
