For Allergic Rhinitis "Allergies had absolutely taken over my life. I was regularly sniffly if not in full blown sneezing attacks all year round. I'd tried everything I could find and nothing ever worked. When a new doctor suggested I tried this I didn't expect it to my any different but its been life changing. As long as I keep taking this one or two sprays a day, it keeps my symptoms at bay. If I forget it for two consectuive days they come back with a vengeance. Its also settled my asthma so I've been able to reduce my inhalers. Yes there's a taste from it but honestly I still couldn't recommend this enough. I'm in northern Ireland so get it free on prescription but I would absolutely pay for if I needed to."
