<<Disclaimer: Verify this information before applying it to your situation.>> Now I know that topical things can be just as harmful as oral. I also know that I cant tolerate shellfish (due to the iodine/salt - Im not really sure which one is the problem) ---- so here are my questions: What will happen if I swim in the ocean? What will happen if I swallow salt water? What about salt in the water softener in my house?
