The antiviral, antifungal, and antibacterial properties of colostrum enable it to kill numerous types of pathogens. Therefore, colostrum is widely used in natural medicine to treat a variety of diseases and disorders. A number of recent clinical studies have shown that colostrum is effective in reversing the inflammation of the digestive tract in HIV/AIDS patients caused by opportunistic infections. Colostrum is effective in preventing intestinal infections by keeping the bacteria from attaching themselves to the intestinal wall, and also by killing the bacteria themselves. A large proportion of the immunoglobulins in colostrum are not absorbed by the body but remain in the digestive tract where they attack organisms that cause disease. Colostrum has proved to be capable of killing Campylobacter, Helicobacter pylori, Listeria, Salmonella, Shigellosis, and five types of streptococci. Allergies and Autoimmune Diseases The PRP in colostrum has been demonstrated to reduce or eliminate the pain, swelling, and inflammation associated with allergies and autoimmune diseases (multiple sclerosis, rheumatoid arthritis, lupus, myasthenia gravis). These effects are related to PRP’s ability to inhibit the overproduction of lymphocytes (white blood cells) and T-cells. Possible Side effects With the exception of allergic reactions in persons who are known to be allergic to cow’s milk, colostrum does not produce any major side effects at any level of consumption. Mild flu-like symptoms that disappear with continued use of colostrum have been reported in children.
