I have hayfever but also have nasal polyps, so can I use these herbal nasal sprays?

Sinuforce Nasal Spray may be helpful in terms of clearing congestion in nasal passages already hampered by containing polyps. The effect will only be temporary, but being natural the remedy doesn’t cause rebound dilation, so that is a benefit. Pollinosan Luffa Nasal Spray reduces inflammation, which may also be helpful. You could try either or both of these to see how well they worked for you.
