Usually what gets clogged is the arteries, and that includes coronary arteries, retinal arteries, carotids and all, but these are areas most often causing trouble. There is a simple, safe remedy for this. See if you can locate a compounding pharmacist where you live and call asking them if they can prepare an 8 ounce supply of SSKI (potassium iodide). Get it quickly and in the meantime type potassium iodide into your search window and go. When references come up look for the Tahoma Clinic one (on my computer I think it appears about the 3rd or 4th page. Dr. Jonathan Wright's article can be downloaded for free, so read it thoroughly, because the decision on going this route is yours, not mine, but you will have good information in your hands to help you make a wise decision.
Start this SSKI at 4 to 6 drops in unchlorinated water once a day. Since it will take several months to unclog these arteries, be sure to have your doctor follow your thyroid function as there is a slight risk of thyroid problems developing with long term SSKI. The other thing that Dr. Wright recommends to use along with SSKI to declog your arteries, is niacin. More than the amount he recommends will be obtained from B complex 100 daily and will not hurt you. If your problem includes any irregularity of your heart rate, also get a 400 to 500 mgm magnesium supplement and take 1 morning and evening.
When you feel that your problems is much better, drop your SSKI to a maintenance dose of 2 drops in unchlorinated water each day. Don't let anyone talk you into an invasive procedure such as coronary artery bypass or placement of stents until you give the above a chance to work it's wonders.
