When we talk about 10 ancient medical traditions, we’re diving into a bizarre museum of cures that once seemed cutting‑edge but now belong in the history books. Civilizations across the globe experimented with everything from scalpels on infants to powdered mouse paste, often with disastrous results. Fortunately, each of the following practices has been retired, allowing modern healthcare to thrive.
10 Ancient Medical Practices Overview
Below, we rank ten of the most eye‑opening, cringe‑worthy, and downright dangerous remedies that ancient healers swore by. Buckle up for a wild ride through time, geography, and some truly questionable hygiene.
10 Cutting TeethFrance
The phrase “cutting teeth” once described a literal surgical procedure, not just a metaphor for learning a trade. In 16th‑century France, physicians believed that a newborn’s gums were so obstinate that a tiny scalpel was needed to carve a path for the emerging teeth. The practice, pioneered by French surgeon Ambroise Paré after he examined a child’s corpse in 1575, involved slicing the gum tissue to expose the hidden teeth. Paré’s notes read, “When we diligently sought for the cause of his death, we could impute it to nothing else than the contumacious hardness of the gums… when we cut the gums with a knife we found all the teeth appearing… if it had been done when he lived, doubtless he would have been preserved.”
Despite its noble intent, the method persisted well into the early 20th century, sparking fierce debate among physicians. Sterile instruments were nonexistent, and the trauma inflicted on infants often proved fatal. While the exact death toll remains unknown, the combination of infection, blood loss, and crude tools made “cutting teeth” a perilous rite of passage for newborns.
9 Mouse PasteEgypt
Ancient Egyptians, plagued by relentless toothaches caused by gritty sand in their diet, turned to an unsettling remedy: dead mice. The theory was simple—grind the carrion into a paste and slather it onto the aching tooth, or even press an entire mouse against the pain point. The practice likely arose because sand eroded enamel, exposing nerves and blood vessels, and the Egyptians believed the mouse’s decay somehow soothed the irritation.
Modern science, however, tells a different story. Applying rotting tissue to exposed nerves is a perfect recipe for infection, turning a manageable ache into a full‑blown abscess. While the ancient healers were earnest, the mouse paste method was more harmful than helpful, and it eventually vanished from medical textbooks.
8 Clay ConsumptionGreece
On the Greek island of Lemnos, a special type of clay called terra sigillata was marketed as a cure‑all for stomach ailments and diarrhoea. Merchants shipped disks of this earth‑derived substance across the Mediterranean, encouraging patients to swallow it for relief. The clay’s composition—rich in kaolin and bentonite—mirrors ingredients found in contemporary anti‑diarrhoeal medicines.
Even Hippocrates praised the benefits of ingesting this mineral, noting its ability to bind toxins and calm the gut. Modern medicine still harnesses the adsorptive power of kaolin‑bentonite blends, proving that while the ancient practice of eating raw clay sounds odd, the underlying chemistry was sound. Today, we reserve clay consumption for specific medical formulations rather than casual munching.
7 Retribution Or CompensationMesopotamia
In circa 1700 BC Mesopotamia, King Hammurabi codified a set of laws that, among other things, regulated surgical practice. A successful operation earned the physician a payment in shekels proportional to the patient’s social standing. Conversely, a botched surgery could cost the doctor his hand—especially if the patient was of high rank and did not survive.
Mesopotamian medicine featured two main practitioners: the ashipu, a sorcerer who identified and expelled malevolent spirits, and the asu, a more conventional physician who applied herbal poultices and plaster casts. Hammurabi’s code only imposed penalties on surgeons who wielded a knife; non‑invasive healers faced no legal retribution, which discouraged risky incisions and nudged practitioners toward less invasive, homeopathic treatments.
6 Have Some PooEgypt
When ancient Egyptians treated eye infections or wounds, they often reached for an unlikely pharmacy: animal dung. Pig, donkey, lizard, and even child excrement were ground into salves or taken orally, based on the belief that the resulting pus was therapeutic. Egyptian physicians thought that encouraging pus formation helped draw out disease, a notion we now know to be backward—pus signals infection, not cure.
Modern medicine has reclaimed a sanitized version of this practice. Fecal microbiota transplantation (FMT) uses screened donor stool to restore healthy gut flora in patients suffering from severe Clostridioides difficile infections. Advances have even produced freeze‑dried “poop pills,” allowing clinicians to deliver the treatment without fresh donor material. While the ancient approach was unsanitary, today’s controlled use of feces saves lives.
5 Partial Tongue RemovalEurope
Hemiglossectomy, the surgical removal of half a tongue, is a legitimate modern treatment for oral cancers. In the 18th and 19th centuries, however, European physicians misapplied the procedure, believing that excising part of the tongue could cure a stutter. The logic was that removing tissue would somehow eliminate the involuntary speech interruptions.
The reality proved far more brutal: patients suffered from severe infection, massive blood loss, and permanent speech impairment. The misguided operation persisted until rigorous scientific studies demonstrated its ineffectiveness for speech disorders, prompting a shift toward speech therapy and safer surgical indications.
4 TobaccoNorth America
Native American cultures revered tobacco as a versatile remedy, employing it for chronic pain, tuberculosis, and a host of other ailments. The plant’s leaves were smoked, chewed, or ground into poultices, and the tobacco used was pure, free from the chemical additives found in modern cigarettes.
Despite its historical medicinal reputation, tobacco is a potent toxin. By the 19th century, physicians were prescribing it for ringworm, constipation, hernias, and infections—often orally or rectally. Today, we recognize nicotine’s addictive properties and the severe health risks of smoking, and medical professionals no longer endorse tobacco as a therapeutic agent. If you’re looking to quit, countless cessation resources are available.
3 Grub SalvesAboriginal Australia
Aboriginal Australians once harvested the larvae of the witchetty moth (Endoxyla leucomochla) to create a healing salve. The grub‑worms were ground into a paste and packed into cuts or abrasions, where they acted as a natural barrier, keeping out air and bacteria while promoting tissue regeneration. The method proved surprisingly effective for wound care.
While the practice has faded, the grub remains a nutritional staple in many Indigenous diets. Today, the insects are roasted, boiled, or ground into cakes, and they’re celebrated as a protein‑rich delicacy. Visitors to Aboriginal communities are often offered these treats, and refusing is considered impolite.
2 IrritationWorldwide
Counter‑irritation, the principle of creating a mild new discomfort to distract from a greater one, is something we all do when we scratch an itch. Ancient physicians turned this instinct into a brutal therapy: they would repeatedly reopen wounds, cut into injuries, and pour irritating concoctions over the fresh lesions, hoping the new pain would mask the original ache.
Historical variants included inserting inflamed limbs into anthills, scorching skin with hot irons or acid to produce blisters, and cutting saw‑shaped wounds to lodge dried peas or beans, which were then replaced weekly to prevent healing. Leeches were also employed for bloodletting in various body cavities, even purportedly to calm “sexual excitement” in women. Modern medicine retains a gentler echo of this concept through acupuncture, which may stimulate natural pain‑killing chemicals without the gruesome side effects of antiquity.
1 Babylonia
In ancient Assyria and Babylon, castration was a medically sanctioned procedure, though its primary purpose was social rather than therapeutic. Physicians performed orchiectomy to create eunuchs for service in royal harems. The operation typically involved removing only the testicles, leaving the penis intact—a practice distinct from later Turkish customs that excised both organs.
Violating a man’s genitalia was a grave crime: a woman who crushed a man’s testicle faced finger amputation, and damaging both testicles could result in the loss of both her nipples. Though the practice faded, modern equivalents such as chemical castration are employed as punitive measures for sexual offenders, underscoring how the medical profession’s role in altering reproductive capacity has evolved dramatically.
