Great for hay fever and sinusitis. Easy to take and use. Significant improvement in symptoms after 2 days of use.

I've been taking it for a few years now and it's the only spray that you can take permanently without damage.

In the case of allergy symptoms such as a blocked nose caused by house dust etc., the product can be used well. Depending on the symptoms, a different hay fever spray may help better, but this would have to be determined individually through tests.
