Suffered for nigh on twenty years with sinus allergies. Couldn't open my eyes during the height of the allergy season as they would crust up and I had to prise them open and remove the flaking pollen that had gathered in my eyes. It was like my eyes were a magnet for pollen. My nose was also constantly blocked like I had a really bad cold. In desperation I sought the advice of a natural healer and she recommended I try a pollen barrier, natural of course. I purchased sinubalm and haymax just in case one worked and the other didn't. They both worked equally well and I only expected them to give me slight relief from the blocked nose. Wow! was I amazed when the other symptoms, crusted eyes, sore throat, streaming eyes, all subsided. Now I don;t have to hide myself away indoors any more.
