it's 1/2 tsp to 1-1/2 tsp natural/unrefined salt (not the commercial/boxed salt sold in stores). put that in 1 quart
of water and warm it up.
another option is a pre-mix formula called NeilMed sinus Rinse. you can find this is stores like Longs or check out neilmed.com. i haven't used it but my co-worker use it and he said it works.
