Etymologist Barry Popik’s chronology finds the sentence first in a colon-therapy advertisement in the Daily News-Record of Miami, Oklahoma, dated 24 September 1944 — not in Hippocrates, and not in a text by any of the other men credited with it. Popik notes the line is pinned on both Hippocrates and the Nobel laureate Élie Metchnikoff, but that “it’s not clear what writing of theirs is most similar to the saying.”
“Death begins in the colon” not Hippocrates. No text by Hippocrates has been identified containing it; the earliest appearance documented by etymologist Barry Popik is a colon-therapy advertisement in the Daily News-Record (Miami, Oklahoma), 24 September 1944. Élie Metchnikoff's The Prolongation of Life (English translation, 1908), often named as the source, does not contain the phrase. — Quotle.info

DEATH— BEGINS IN THE COLON

Advertisement, 1944
Transcribed by Barry Popik from Newspapers.com. The reading “bloom stream” is his transcription of the ad as set; “blood stream” is the evident intent. The ellipsis is Popik’s.
Barry Popik’s entry, dated 12 September 2011, records that the saying “has been credited to” Hippocrates and to Metchnikoff, “although it’s not clear what writing of theirs is most similar to the saying,” and dates the phrase in print “from at least 1944” — see the citation list ↗.
The same page transcribes a near-variant from The Medical Summary, September 1919: “We don’t know whom to credit for the dictum that ‘Cancer begins in the colon.’” — Popik, 1919 citation ↗.
Metchnikoff’s actual argument is in The Prolongation of Life: the large intestine is “certainly useless in the case of man,” and waste “retained in the large intestine for considerable periods, becomes a nidus for microbes which produce fermentations and putrefaction harmful to the organism.” The phrase itself is absent — search the full text ↗.
Wikiquote’s Hippocrates page carries a Disputed section for exactly this class of line — “Let food be thy medicine and medicine be thy food” is listed there as not found in the Hippocratic corpus — and this quote does not appear on the page at all: Wikiquote: Hippocrates ↗.
No author or work of origin has been established, so no rights status can honestly be asserted for the sentence. The earliest documented carrier is an unsigned 1944 American newspaper advertisement; Élie Metchnikoff’s The Prolongation of Life (English translation, 1908) is old enough to be public domain in the United States but does not contain the phrase, so it cannot be the source that clears it.

Four claimants, no text
This is a phrase with more credited authors than sources. Each attribution below is real — people really do print it — and each one collapses when you ask for the page it appears on.

The popular creditHippocrates Unsupported
Popular science repeats it as ancient: Ray Kurzweil and Terry Grossman’s Transcend (2011) writes “as Hippocrates observed centuries ago, ‘Death begins in the colon.’” No Hippocratic text has been pointed to. Barry Popik, who compiled the citations, says only that it’s not clear what writing of his is most similar ↗. Hippocrates is a standing magnet for unsourced medical maxims — Wikiquote files “Let food be thy medicine and medicine be thy food” under Disputed ↗, noting it is not found in the Hippocratic corpus.

The scientific creditÉlie Metchnikoff Not in his book
Bernard Jensen’s Dr. Jensen’s Guide to Diet and Detoxification (2000) opens chapter one by stating the expression “apparently originated with” Metchnikoff during his Pasteur Institute years. The theory did; the sentence did not. A full-text search of the 1908 English translation of The Prolongation of Life ↗ returns no occurrence of “death begins” or “begins in the colon.”
✕
The coinage claimBernard Jensen Too late
Ted Aloisio’s Blood Never Lies (2004) says the chiropractor Bernard Jensen “coined the phrase” while his medical contemporaries laughed. But the words were already set in a newspaper advertisement in 1944 under a different practitioner’s name, per Popik’s citation list ↗ — and Jensen’s own book credits Metchnikoff, not himself.
✕
The third claimantNorman W. Walker Unsourced
Peter Glickman’s Lose Weight, Have More Energy & Be Happier in 10 Days (2005) says the juicing author Norman W. Walker “is credited with the statement.” Credited by whom, and in which of his books, is not said — and the chronology ↗ records no Walker citation.
✓No page has ever been produced — not by Hippocrates, Metchnikoff, Jensen or Walker. The earliest appearance Barry Popik records ↗ is a colon-therapy advertisement in the Daily News-Record of Miami, Oklahoma, 24 September 1944, and it spread through naturopathic and chiropractic advertising from 1976 onward.
Context
Why a slogan needed a Greek
The idea underneath the phrase is real medical history. Through the nineteenth century, auto-intoxication — the belief that waste held in the bowel poisons the rest of the body — was mainstream doctrine, and Metchnikoff gave it a Nobel laureate’s imprimatur at the Pasteur Institute. What he argued was narrower and stranger than the slogan: that the large intestine is an evolutionary hangover, a reservoir that let running mammals defer defecation, and that the putrefaction it harbours shortens life.
The slogan itself is American, commercial and much later. Popik’s citations are advertisements and lecture write-ups — a chiropractor’s colon-therapy ad in 1944, a Chicago naturopath’s “main tenet” in 1976, ads in California, Georgia and Washington through the 1990s. Attaching it to Hippocrates does a specific job: it converts a sales line into an ancient verdict.
“A triumph of ignorance over science” — Edzard Ernst’s 1997 title for the colonic-irrigation revival
The 1919 near-variant, and what became of the theory
A near-variant ran earlier. In September 1919 The Medical Summary discussed the dictum “Cancer begins in the colon,” adding that “We don’t know whom to credit” for it — the same anonymous-maxim shape, a quarter of a century before the death version surfaces.
By 1997 Edzard Ernst was reviewing auto-intoxication in the Journal of Clinical Gastroenterology and concluding that once “it became clear that the scientific rationale was wrong and colonic irrigation was not merely useless but potentially dangerous, it was exposed as quackery.” The slogan long outlived the doctrine it summarised.

1845–1916 · Russian-born biologist at the Pasteur Institute · 1908 Nobel laureate in Physiology or Medicine
Metchnikoff shared the 1908 Nobel Prize in Physiology or Medicine with Paul Ehrlich for work on immunity, then spent his later years at the Pasteur Institute arguing that microbes in the large intestine poison the body and hasten old age — the theory of intestinal auto-intoxication. In The Prolongation of Life: Optimistic Studies he called the human large intestine “certainly useless” and prescribed soured milk to crowd out putrefactive bacteria, which is why he is the figure most often named as the source of this slogan. He never wrote the sentence. The phrase appears nowhere in the 1908 English translation of the book, whose full text is searchable at Project Gutenberg.
