Abstract Background Agaricus blazei Murill AbM is an edible Brazilian mushroom that has been used in traditional medicine for a range of diseases. It has been shown to have anti-infection and anti-tumor properties in the mouse which are due to induction of Th1 responses. On the other hand IgE-mediated allergy is induced by a Th2 response. Objective Since according to the Th1 Th2 paradigm an increased Th1 response may promote a reduced Th2 response the aim was to examine whether AbM had anti-allergy effects. Methods A mouse model for allergy was employed in which the mice were immunized . with the model allergen ovalbumin OVA . Additionally the animals were given a mushroom extract AndoSan mainly 82 containing AbM but also Hericium erinaceum 15 and Grifola frondosa 3 or PBS . either a day before or 19 days after the immunization. The mice were sacrificed
