Retrieved sources document that there is a widely discussed online claim and question regarding whether Louis Pasteur made a deathbed admission about terrain theory.
In blood circulation (systemic circulation), the order of blood circulation is that arterial blood flows into capillaries only after venous blood refluxes. The human body controls the flow of arterial blood into capillaries by controlling the flow of venous blood. The refluxing power of venous blood changes with the rotation and revolution of the earth, and leads to changes in arterial blood obtained by cells, tissues and organs. If the refluxing power of venous blood of the lungs has a problem, the actual amount of blood obtained by the lungs will be less than the amount of blood distributed to the lungs by the human body (supplying the lungs with nutrients and oxygen they need), and what Pasteur called “the terrain” (There is a paragraph in Seasons of Life: “On his deathbed, Louis Pasteur, the founder of the germ theory of disease, allegedly said, ‘the germ is nothing, the terrain is everything’.”) will form in the lungs. The severity of problems induced by the intensity of venous reflux changes with time, leading to the variation of lung’s susceptibility to viral infections with time.

## Question
On many 'health' sites defending terrain theory (the theory that the state of the body, not just germs, is the primal factor for disease development) one finds quotes that Louis Pasteur is said to have admitted that terrain theory was right. Here, for example, [Prestige Wellness Center from Dr. Ray Andrew](https://www.prestigewellnessinstitute.com/blog/its-the-terrain):
> By contrast, Pasteur’s friend, physiologist Claude Bernard, taught that the ‘terrain’ of the human body was more important than the ‘pathogens’ that infect it. We are surrounded by, and even harbor, microorganisms in our bodies. When exposed to pathogens, we become ill if our defenses are weakened by deficiencies or toxicities. Unlike the germ theory, the terrain theory explains why some people get sick while others, when exposed to the same pathogens, do not. For this reason, it is said that on his death bed, Pasteur a
