It is then, if the body's immune system is weak, that the cold attacks us, and can lead to bronchitis, influenza, or pneumonia. In addition, one needs to remember that antibiotics are ineffective against viral infections. There are several vitamins and herbal supplements that will build and maintain a healthy immune system. Vitamin A assists in healing inflamed mucous membranes, and boosts the immune system. Vitamin B Complex aids in healing, and reduces stress, allowing the body to rest.
Zinc strengthens the immune system as well.
Herbs should never be over looked when considering any type of illness. Echinacea has recently become a popular herb in treating colds. The polysaccharides found in echinacea enhance the immune system. Researchers have discovered echinacea increases T cells, and interferon which fight against viruses. Echinacea is to be taken at the onset of illness, and should be discontinued once healing is noticed.
