Sinus Infection Remedies - Danger!!! A MSDS sheet for Betadine stated the following: "Reactivity - A mixture of equal parts of a 10% povidone iodine solution (Betadine) and hydrogen peroxide 3% exploded about 100 minutes after mixing." Folks, this is the normal Betadine and hydrogen peroxide that you buy in the store! I was actually considering putting a few drops of these in some salt water and using it in an atomizing spray bottle (these are normally called "non-drip."). Not any more! On the other hand, after all of their warninings, I like the few drops of Betadine in a spray bottle of salt water, it works great! Betadine is one of the few things that kills viruses, it is stable in storage and and has a residual effect. To be on the safe side I will be keeping an eye out for possible iodine toxicity.
Another website states "REMEMBER: Betadine and tincture of iodine are not the same thing. Tincture of iodine is NOT safe to use. Tincture of Iodine is poisonous! Never use tincture of iodine when piercing skin. It dangerously inflames mucus membranes and if put on a wound or piercing it can result in a toxic level of iodine absorption." Therefore, I think I'll stick with the Betadine. http://www.phlebotomypages.com/iodine.htm
I took one tablet of Iodoral (iodine supplement) a day for a year, my blood calcium and alkaline phosphatase levels rose to above normal. A year later my blood test results were even higher, so the doctor gave me a PTH (parathyroid--which sits right next to the thyroid) blood test, and it was very high. As the only thing that I had changed in my life was taking Iodoral, I quit taking it, and 3 months later all my tests were back to normal. The parathyroid's job is to take calcium out of your bones and give it to the brain, but too much in your blood can mean heart attacks, strokes, and osteoporosis. There really aren't any symptoms of an over active parathyroid until it's very bad...feeling cold all the time, brain fog, are two. If you've been supplementing with Iodoral or iodine I suggest you get your blood calcium level tested, then alkaline phosphatase, then PTH (which is expensive, so save that for last).
Sometimes kelp is often improperly processed and has high heavy metals and/or contaminants. This is a well known fact that supplements also have fillers added. In that case, your next best choice is just use iodine foot painting or eat some seaweed. I never seem to have problems with eating seaweeds often sold in supermarkets. I guess they have better manufacturing standards as the market is much larger than those that take kelp supplements.
