Took me a while but I found it. My oops, it was my husband who posted the recpe for me, coincidentally, I as in CA at the time. Which is where I am now.
Saline for Sinus irrigation:
1 quart distilled H2O...
1 tsp baking soda- buffers the solution
2 tsp noniodized salt- canning, pickling, sea salt are noniodized.
Mix in a nonbreakable tupperware type container. This should last a few days.
You can use a bulb syringe or a one of many types of irrigators available at the drug store. Water pik makes an attachment that you can also use. If you use a bulb syringe make sure you replace it every few weeks.
Pour about 4 ounces in a cup and then transfer to the syringe, don't stick your syringe into the quart jug. You can tilt your head forward or backward or keep it straight when you squirt the solution into one nostril. Don't try to "suck it in", this will open your vocal cords and may cause you to aspirate (choke). This is really very beneficial for those that have had sinus surgery (FESS). For those with allergies but without surgery it will still help keep the sinus passages somewhat clear of mucus and clean the nasal mucus membranes of allergens to some extent.
