Today we have many external toxins that our bodies must deal with. They are in the food we eat, in the form of pesticides or chemical additives used for longer shelf life. Toxins are in the air that we breathe from automobiles and factories. In addition, our lives are full of stress and excitement which creates internal chemicals that turns into toxins when in excess. All these factors contribute to weakening of our immunity system. An individual's immunity tends to get compromised with day-to-day physical and psychological stress.

It is generally believed that biological organisms require certain amount of stress in order to maintain their well-being. When stress occurs in quantities that the system can't handle, it produces pathological changes. The immuno compromised person becomes prone to slightest microbial assaults and his condition further deteriorates.
