Collins, AM, et al. Bovine milk, including pasteurized milk, contains antibodies directed against allergens of clinical importance to man. International Archives of Allergy and Applied Immunology 96:362-367 (1991). The presence of antibodies against many of the most common allergies in man, including ryegrass pollen, house dust mites, Aspergillus mold and wheat gluten, were detected in bovine colostrum.

Delespesse, G. Polypeptide factors from colostrum. US Patent #5,371,073 (1994). IgE (the immunoglobulin involved in allergic response) binding factors (IgE-bf) and IgE suppressor activity (IgE-SF) obtained from colostrum have been successfully used to treat allergies.

Yoshioka, Y, Kudo, S, Nishimura, H, Yajima, T, Kishihara, K, Saito, K, Suzuki, T, Suzuki, Y, Kuroiwa, S, Yoshikai, Y. (2005) Oral administration of bovine colostrum stimulates intestinal intraepithelial lymphocytes to polarize Th1-type in mice. International Immunopharmacology 5(3):581-90. Stimulating the Th1 immune response from the Th2 skewed immune response in infancy is important to reduce the incidence of allergies. Mice given colostrum showed a polarization to Th1 response in intestinal intraepithelial lymphocytes while intestinal microflora and IgA levels showed no change. This suggests that colostrum may protect from both infectious disease and allergies mediated by Th2 type responses.
