Immunity is the totality of systems and mechanisms that help the body to preserve its genetic integrity, and at the same time its uniqueness. Immunity can not be changed within a few days by eating or drinking something. The basis of the immune system is the ability to distinguish everything between yourself and the outside: who you are and what's in the environment. If this is lacking, the body can not resist environmental factors. It causes damage that we know as an autoimmune disease. Natural supplements that contain Kalawalla and licorice can help to improve immunity system.
