Don't know if anyone else has tried using the Herbal Spray as nasal spray but I'm giving it a go. I have had this pressure in my nasal cavity for 14 months which will not go away. I directly link it to chem-trails. The town I lived in most my life didn't see much chem-trail activity it wasn't until I moved on the east-side of Cleveland when I noticed chem-trails almost daily. The came the sinus pressure.
I have tried the Herbal Spray I & II both burn a little for about 5 seconds.
