Your body is is your temple, protect it from all enemies, but creating continuous and lasting homeostasis

It's not the germ, but the condition of the host body is responsible for every single disease.

As summarized and greatly simplified by author Walene James10—and ridiculed by Mark Crislip11 in Science-Based Medicine—Béchamp’s basic message was that:

Disease arises from micro-organisms within the cells of the body.
These intracellular microorganisms normally function to build and assist in the metabolic processes of the body.
The function of these organisms changes to assist in the catabolic (disintegration) processes of the host organism when that organism dies or is injured, which may be chemical as well as mechanical.
Microorganisms change their shapes and colors to reflect the medium.
Every disease is associated with a particular condition.
Microorganisms become “pathogenic” as the health of the host organism. deteriorates. Hence, the condition of the host organism is the primary causal agent.
Disease is built by unhealthy conditions.
To prevent disease we have to create health.
Among those who rejected germ theory, instead championing the influence of diet, climate, ventilation, hygiene and sanitation in causing disease were Florence Nightingale and Rudolf Virchow.

Rudolf Virchow, an early opponent of the germ theory of disease, believed that germs do not cause disease but instead gravitate to the diseased area as scavengers, to feed on and clean up the dead tissue caused by the pathogenic process. Virchow stated in his later years, “If I could live my life over again, I would devote it to proving that germs seek their natural habitat—diseased tissues—rather than causing disease.”12

Western Medicine Rules
Western medicine fiercely protects the germ theory of disease, scorning and dismissing Béchamp’s ideas out of hand. There is no doubt that much of what Béchamp was able to determine has been supplanted now by scientific resources unavailable to him at his time, but that can also be said of Pasteur’s theories. Such a narrow view of disease misses the gist of Béchamp’s teachings: the importance of supporting a strong internal defense system to ward off disease and attain true health rather than relying on drugs and vaccines as a sledgehammer to treat symptoms and attempt to destroy germs.

Many disease-causing microbes are normally present in the body and do not cause disease as a matter of course but are kept at bay in people who have healthy immune systems. Other infectious microbes can spread from person to person via water, air, insect bites or exposure to infected body fluids and have the potential to cause serious complications in an immune compromised host.
