hay Fever / Pollen Allergy

I have been suffering with severe hay fever for about 22 years. I react to hazel, alder, ash, birch, most pollens. I have really tried almost all the remedies available. I have now started taking 3 capsules of Aronia per day, and the symptoms have practically disappeared. It took a few days for the desired effect to kick in. Currently, I am taking the Aronia extract as a preventive measure against inflammation and to fill my "reserves". I wouldn't have expected it to be so effective against my allergy...
