A scientific study reported in the Journal of Allergy and Clinical Immunology isolated the substance in cowshed dust that possibly protects farm children from developing allergies and allergic asthma — namely the plant sugar molecule arabinogalactan. If high concentrations are inhaled during the first year of life, it inhibits the immune system from excessive defense reactions. It has long been know that children who grow up on farms are less prone to allergies and allergic asthma. The scientists now plan to investigate whether arabinogalactan can be used as prophylaxis or whether it is also suitable for the treatment of allergies and allergic asthma. It is conceivable that arabinogalactan could be used as spray or nose drops because it is highly water-soluble. For access to the full study, please click here.
