Allopathic physicians see disease as one of two different things happening in the body.
The first scenario is that there is an invader from the outside world that needs to be eradicated. An example of this would be when someone gets an infection. Our medical answer to this is to take an antibiotic to kill the invader. The second way in which allopathic medicine sees disease is that there is a chemical imbalance in the body that needs to be balanced. An example of this would be an allergy.
