"HayMax Pure is an award-winning pollen barrier designed to trap allergens using natural ingredients. It's proven to trap over 1/3 of pollen grains and dust & pet allergens (National Pollen & Aerobiology Research Unit trials, 2009 & 2012).HayMax™ is an organic, drug-free, allergen barrier balm which can help bring relief from these symptoms. Made from natural ingredients, trials have proven that this award-winning balm helps trap pollen, dust mite droppings and animal dander. When applied to the nostrils, it traps a proportion of the allergen which would otherwise travel up the nasal tract, where it would cause the reactions. The balm works on the principle that if enough is trapped, this will keep you below your sensitivity or trigger level so the reactions for that allergen will not be triggered. Can be used with other medication. Suitable for children and pregnant women"
