If enough anti-allergic probiotics are supplemented in the intestine, excessive immunoglobulin E(IgE) antibodies in serum are reduced, the secretion of interferon IFN-γ is stimulated, and the production of human immunoglobulin E(IgE) is inhibited, the allergic constitution can be effectively improved through immune regulation aiming at the upstream source of allergy. Not all probiotics have this magical effect. At present, Kangminyuan Probiotic Granules, an antiallergic probiotic, has developed from antiallergic probiotics to Kangminyuan enhanced probiotics rich in five kinds of antiallergic strains, which are widely used in the regulation of allergic patients and allergic constitution, especially children allergic patients. Let children with repeated allergies gradually get rid of or get rid of dependence on antihistamines or corticosteroids.
