Antoine Bechamp
French microbiologist, Antoine Bechamp, Professor of Medical Chemistry and Pharmacy at the University of Montpelier, was a contempory of Mr. Pasteur. Bechamp, along with Claude Bernard had a different idea about germs. They believed that germs where pleo-morphic, that they changed depending on the terrain. This means that disease usually arises from within the body, that healthy microorganisms exist within the body, and microorganisms change and transform based on their environment. Microorganisms become dangerous when there are unhealthy conditions within the body.
If Dr. Bechamps theory is correct, then our health is a direct reflection of the conditions of the body, and thus we are responsible for our health.
