One of the things that fascinates me most isn’t just biology. It’s language.
Words are powerful. They don’t just describe reality—they shape the way we think. They influence the questions we ask, the stories we believe, and ultimately the way we approach health. If someone changes the meaning of a word, they can change the story people believe.
Today, I want to explore one fascinating example: sepsis.
Most people hear the word sepsis and immediately think of a dangerous infection. But that’s not what the word originally meant.
The word sepsis comes from the ancient Greek sēpsis, meaning putrefaction, decay, or rotting. It comes from the Greek verb sēpein, meaning “to make rotten” or “to decay.” Long before anyone knew what bacteria were, physicians simply observed that tissue could become foul, stagnant, and break down.
Here’s what I find interesting. Originally, the word described what physicians observed. It did not describe what they believed caused it.
Observation is not the same as explanation.
Over time, as germ theory became the dominant framework of medicine, the meaning shifted. Today, sepsis is defined as a life-threatening condition in which the body’s response to an infection leads to widespread inflammation, tissue damage, and organ dysfunction.
Whether or not you agree with every aspect of that definition isn’t really my point. My point is that something subtle happened. A word that originally described a state of decay gradually became associated with a specific explanationfor why that state exists. That shift in language influences the way we think.
The same observation can produce two completely different stories. Imagine two practitioners looking at the same patient. One says, “An infection is attacking your body.” The other says, “Your tissues have become stagnant and are beginning to break down.”
They’re observing the same situation, but they’re asking completely different questions. The first asks, “What is attacking the body?” The second asks, “Why did the tissues become stagnant in the first place?”
The observation hasn’t changed.
Only the story has.
During one of our recent webinars, my brother Josh made a joke that actually stopped me in my tracks. He said, “You become blocked, they fill you full of stuff, and you literally become a septic tank.” Everyone laughed, but then something else occurred to me.
We use the word septic every day in a completely different context: the septic tank.
Why do we call it a septic tank?
Because it’s literally a place where organic material is allowed to decompose. Waste collects. Material becomes stagnant. Microorganisms participate in breaking it down.
The tank wasn’t named because it contains dangerous germs. It was named because it is a place of sepsis—a place of putrefaction and decay.
No one would argue that the bacteria created the waste. The waste was already there. The microorganisms participate in breaking it down.
I find it fascinating that the same ancient root gave us both the medical word sepsis and the everyday term septic tank. That connection makes me wonder whether we’ve forgotten what the original word was actually describing.
From the terrain perspective, the questions naturally become different. Instead of immediately asking, “What invaded the body?” we begin asking different questions.
What became stagnant?
What stopped moving?
Where is circulation compromised?
Where are normal pathways of elimination no longer functioning?
Why has this terrain become difficult for healthy tissue function?
Those questions lead us down an entirely different path.
This is one reason I find Reckeweg’s Homotoxicology model so interesting. As the terrain becomes increasingly congested and less capable of eliminating waste, the body has fewer options available. We often observe increased compensation, increased inflammation, and attempts to restore balance. The body continues trying to adapt.
Whether or not you interpret those adaptations the same way I do, I think they’re worth observing before jumping to conclusions.
Another word I’ve become increasingly curious about is infection. For many people, infection immediately means, “Something has invaded me.” But I often wonder whether we’re observing part of the body’s attempt to clean up damaged tissue and restore order.
That doesn’t mean every situation is harmless, and it doesn’t mean severe illness should be ignored. It simply means we should keep asking better questions.
For me, this article isn’t really about sepsis.
It’s about language.
Words shape medicine. Words shape perception. Words shape the questions we ask.
When you begin studying the origins of medical words, you discover that many of them carried very different meanings hundreds—or even thousands—of years ago. Sometimes we’ve forgotten what they originally described.
This article isn’t asking you to automatically accept another explanation. It’s simply inviting you to notice something.
Words change.
Definitions change.
Stories change.
And when the story changes, it’s worth asking why.
Perhaps the most important question isn’t, “What’s attacking the body?”
Perhaps it’s, “Why did the terrain reach this state in the first place?”
I find that to be a much more interesting question.
Because sometimes changing one word changes the entire story. And when the story changes, so do the questions we ask.
Ultimately, the questions we ask determine the answers we’re likely to find.
Food for thought.
Keep asking questions.
Keep thinking critically.
