Our immune system is our body’s key defense mechanism for preventing and fighting off disease.  It is your body’s own personal army and consists of cells, organs and tissues that work together to defend the body against “foreign invaders” such as bad bacteria, fungi and parasites.  It is the immune system’s job to keep  these invaders out or destroy them altogether. If you have a weak, or weakened immune system, steps such as regular detoxification of toxins, added nutrition and getting a good night’s sleep will be of prime importance.
