So sorry to hear your OH is suffering Ann. My Son has had 3 ops for Sinus problems and still suffers. His consultant told him to use this to ease the problem. Sqad will suggest if this is helpful or not.
"Making a Sinus Irrigation Solution
With its cleaning and bacteria-bashing powers, sodium chloride, more commonly known as salt, is the essential ingredient in a sinus irrigation solution. However, many add sodium bicarbonate, more commonly known as baking soda, to the mix as well in order to lessen the sting. Melissa Pynnonen, M.D., of the University of Michigan recommends using 1/4 tsp. of each dissolved in 8 oz. of distilled water, to be used once or twice a day. Look at the ingredients of a commercial packet of sinus rinse powder and you'll find sodium chloride and sodium bicarbonate. There's no need to spend money on prepackaged powders unless you value the convenience."
