nasal irrigation, AKA a neti pot

Safety concerns are there, but they're not the main focus of this page.

To maximize comfort, make sure the water is slightly warm.

Solution

What's included in those saline packets that come with neti pots:

• It's almost entirely table salt (NaCl). Typically this is medical grade salt, meaning it's high purity.
• baking soda
• some rare additions:
  • povidone-iodine, AKA iodopovidone [2]
