How does a grass extract help if the cause of allergies is generally grass pollen?
• Pollen grasses are carriers of protein substances which, when inhaled release these proteins when in contact with a moist surface. This results in the release of substances, e.g. histamine and other mediators which cause swelling and constriction of the airways. Rye grass extract is not pollen and is not a carrier of these proteins. Also its primary action is not related with mediators like histamine.
