I use Naturalist vitamin E-OIL Prod.No.827 a few drops in each side and i can breathe in the cold again. The oil absorbs into the nasal tissue and into your blood stream it is actually good for your heart. I call it nase-oil I use it from a dropper bottle. It soothes the tissues and opens up the air passages. I have also used sesame oil orderless and clear you can eat it rub it on your face put some in your nose sesame oil is great.
