I got Betadine Nasal Spray from Australia (I think), made in Austria, but it’s not with iodine. It uses carrageenan. Check it out. Looks pretty darn good.

That ain't right. Iodine is a disinfectant. Carageenan is seaweed, and it's used in foods as a thickening agent.

The iota-carrageenan nasal spray can also be made at home:

We made this. When buying the iota-carrageenan powder, get one that does not have dextrose or other sugars in it.
