Thanks, I appreciate your concern. I wish you could have provided information backing it. There's a ton of studies to pick from that indicate if properly diluted, it's a helpful remedy. Like you said, they also say, not to ingest it. I know when I nasal rinse, I don't swallow it. I'm sure most don't.

I did look up concerns regarding saline and iodine nasal rinsing and wasn't able to find any. The only warnings I read was that if you have a sensitivity to iodine, to be careful and/or avoid it.
