I was given this by a doctor sometime back. This is a sea-salt nasal spray which is used to cleanse the nostrils. It works great except that it has Xylitol added to it. That totally ruined it for me. Each time I used it, it felt like I was spraying brown sugar water into my nostrils which flowed down to the back of my throat. I've used nasal sprays which only have sea-salt. Those were great.
Verdict: I hated this. It would have been great without Xylitol.
