Stone Age healing wasn’t superstition — it was applied botany, surgery, and pharmacy. And the evidence for who practiced it points in a direction that shouldn’t surprise anyone but somehow still does.


There’s a skull in a museum in Washington, D.C., that should stop you in your tracks.

It belonged to a Neanderthal man who lived roughly 45,000 years ago in what is now Shanidar Cave, northern Iraq. Anthropologists call him Shanidar 1. His injuries read like a medical chart from a disaster ward: a crushing blow to the left side of his face that blinded his left eye, a withered and eventually amputated right arm — probably from birth or early injury — degenerative damage to his right leg and foot that left him with a severe limp, and extensive arthritis across his entire skeleton.

He lived to be somewhere between forty and fifty years old. In the Pleistocene. With one arm, one eye, and a body that couldn’t hunt, run, or fight.

Somebody kept him alive.

Not for a week. Not through a single crisis. For decades. Somebody fed him when he couldn’t hunt. Somebody guided him over rough terrain when his leg failed on loose scree. Somebody treated his pain — the arthritis alone would have been agonizing — with whatever they had. And given what we now know about what Neanderthals had, “whatever they had” was a great deal more than anyone assumed fifty years ago.

Shanidar 1 is not evidence of primitive survival. He is evidence of medicine. Sustained, knowledgeable, deliberate care delivered over years by someone who understood pain, nutrition, mobility, and the pharmacology of the plants growing on the hillside above the cave.

The question is: who was that someone?

Evidence They Healed

Shanidar 1 isn’t an anomaly. He’s part of a pattern that runs across the entire Paleolithic — a pattern of survival that can only be explained by the existence of healers.

At the same cave, Shanidar 3 survived a deep stab wound to the chest — likely a projectile injury that penetrated between the ribs. The wound partially healed before he died, meaning he lived for weeks after the injury. Someone managed a penetrating chest trauma without antibiotics, surgical thread, or sterile dressings. Someone kept a punctured lung from killing him long enough for bone to start knitting.

At Romito Cave in southern Italy, a young man with a severe form of dwarfism — acromesomelic dysplasia, a genetic condition that would have left him profoundly short-limbed — survived to roughly seventeen years of age in a Paleolithic community that depended on physical mobility. He was buried with apparent care and ceremony. He lived because people carried what he couldn’t carry, and someone managed the joint pain and complications his condition would have caused.

At La Chapelle-aux-Saints, the “Old Man” Neanderthal — severely arthritic, missing most of his teeth, with a badly deformed spine — survived well past the age of usefulness by any ruthless evolutionary calculus. Someone chewed his food for him, or prepared it soft enough for toothless gums. Someone treated inflammation that would have made every movement agony.

This isn’t scattered anecdote. Across dozens of Paleolithic and Neolithic sites, the pattern repeats: individuals with severe disabilities, chronic conditions, and catastrophic injuries who survived far longer than they could have alone. The only explanation is organized care — and organized care requires knowledge.

The Plant Pharmacy

We don’t have to guess what they used. We can test it.

In 2017, a landmark study of Neanderthal dental calculus from El Sidrón, Spain, changed the conversation permanently. Calculus — the hardite plaque that accumulates on teeth — traps microscopic particles of whatever passes through the mouth: food, fibers, pollen, plant compounds. It’s a time capsule of diet and behavior, sealed in enamel and preserved for tens of thousands of years.

The El Sidrón individual had a dental abscess — a painful, dangerous infection. The calculus on the same tooth contained traces of poplar bark, which is rich in salicylic acid (the compound in aspirin), and DNA sequences matching *Penicillium* — the mold genus that produces penicillin. This person was consuming a natural painkiller and a natural antibiotic at the same time, targeted at the same infection.

This was not accidental foraging. Poplar bark is bitter and has no caloric value. You don’t eat it because you’re hungry. You eat it because your tooth is screaming and you know — because someone taught you — that this particular bark makes it stop.

The Iceman, Ötzi, offers a later but beautifully preserved snapshot of a prehistoric medicine kit. Found frozen in the Alps at 5,300 years old, he carried birch polypore fungus threaded onto a leather thong. Birch polypore contains agaric acid, a potent laxative and anti-parasitic compound. Ötzi had intestinal whipworm — confirmed by analysis of his gut contents. He was carrying his treatment on a string around his neck.

Yarrow, chamomile, wormwood, meadowsweet, willow — the pharmacopoeia of the Stone Age reads like a modern herbalist’s dispensary, and in many cases the active compounds have been confirmed by laboratory analysis. These plants work. Not metaphorically. Pharmacologically. The people who used them weren’t guessing. They were practicing medicine within a knowledge system built across thousands of generations of observation, trial, and transmission.

Surgery Before Metal

If the plant pharmacy proves Stone Age people understood internal medicine, what comes next proves they understood surgery. And the survival rates are going to bother you.

Trepanation — the practice of deliberately cutting, drilling, or scraping a hole through the living skull — is the oldest known surgical procedure. It appears in the Neolithic archaeological record across Europe, South America, Africa, and Asia. Thousands of trepanned skulls have been recovered. And a significant number of them show clear evidence of healing — new bone growth around the margins of the hole, which means the patient survived the procedure and lived for months or years afterward.

At the Neolithic site of Ensisheim in France, a skull dating to roughly 5,000 BCE shows two separate trepanations, both fully healed. The patient survived two brain surgeries and lived long enough for the bone to completely remodel. At some Peruvian sites, trepanation survival rates reached an estimated 80 to 90 percent. For context, survival rates for cranial surgery during the American Civil War — performed by trained surgeons with metal instruments, in an era that at least understood the concept of infection — hovered around 50 percent.

Stone Age surgeons, working with flint blades and obsidian scrapers, outperformed nineteenth-century doctors.

And then there’s Liang Tebo.

In 2020, a team published the discovery of a 31,000-year-old burial in a cave on the island of Borneo containing the remains of a young adult whose lower left leg had been surgically amputated. Not torn off by an animal. Not crushed in a rockfall. Amputated — cleanly, deliberately, with evidence of post-surgical care. The individual survived the amputation and lived for six to nine years afterward, walking on the healed stump through a rugged tropical-forest environment.

Thirty-one thousand years ago, someone performed a below-knee amputation in a limestone cave in the rainforest, managed post-operative infection without antiseptic, controlled bleeding without clamps, handled pain without anesthesia beyond whatever plants were available — and their patient walked for another decade.

That’s not folk wisdom. That’s surgery. And it demands a surgeon.

Why Women?

Here’s where the argument needs to be made carefully, because it matters.

We can’t excavate gender. Stone tools don’t come with name tags. A trepanned skull tells us someone performed surgery; it doesn’t tell us who held the blade. Any claim about who the healers were requires inference — but some inferences are stronger than others.

Start with the ethnographic record. Among documented forager and horticultural societies across the world — the San of southern Africa, the Hadza of Tanzania, Aboriginal Australians, dozens of Amazonian and Southeast Asian groups — plant-medicine knowledge is overwhelmingly concentrated among women. Not exclusively. But overwhelmingly. Women gather. Gathering requires deep, systematic botanical knowledge: what’s edible, what’s toxic, what heals, what harms, what ripens when, what grows where. That knowledge base is the pharmacy.

Now layer in the logic of care. In forager societies, who tends the sick? Who sits with a feverish child through the night? Who cleans a wound, changes a poultice, monitors a recovering patient over days and weeks? The same people who are already in camp, already managing children, already processing food, already maintaining the fire. The labor of care and the labor of healing overlap almost completely — not because women were assigned lesser work, but because sustained close-proximity caregiving is the prerequisite skill for medicine. You cannot develop surgical competence without first developing nursing competence. Someone had to notice that pressure stops bleeding before someone could plan an amputation.

Does this mean every healer was a woman? No. Does this mean male healers didn’t exist? Of course not. What the evidence — ethnographic, logical, and circumstantial — suggests is that the knowledge system we now call medicine emerged primarily from the accumulated expertise of women who gathered plants, tended the sick and injured, managed pregnancies and births, and transmitted that knowledge to their daughters across hundreds of thousands of years.

The healer at Shanidar Cave who kept a one-armed, half-blind man alive for thirty years didn’t do it with brute strength. She did it with knowledge — which plants dulled pain, which foods sustained a body that couldn’t hunt, how to splint a limping leg, when to let him rest and when to make him move. That knowledge had a lineage. It came from somewhere. It was taught.

And the most parsimonious explanation for where it came from is the people who spent the most time with plants, with patients, and with the slow, patient work of keeping damaged bodies alive.

What She Carried

Picture the pouch.

Soft hide, gathered at the top with a sinew drawstring, darkened with use and age. She wears it at her hip, always. Open it and you find: dried yarrow leaves, rolled tight and bound with grass fiber — for wounds. A thumb-sized lump of birch tar wrapped in a dock leaf — antiseptic sealant, waterproofing, all-purpose adhesive. Strips of dried willow bark — painkiller, anti-inflammatory, fever reducer. Powdered ochre in a tiny leather packet — styptic, ritual, identity. A bone needle and a coil of fine sinew — for closing deep cuts. Dried meadowsweet flowers, still faintly fragrant — for fever tea and for the dead. A flat river stone, smooth and palm-sized — mortar for grinding fresh plants against.

It’s not magic. It’s a medical kit. Every item in it has been confirmed by archaeological discovery, chemical analysis, or ethnographic parallel. Some of them — willow bark, yarrow, birch tar — appear across multiple independent Stone Age contexts spanning tens of thousands of years and thousands of miles.

She doesn’t call herself a doctor. The word won’t exist for another forty thousand years. But she carries the knowledge, the tools, and the responsibility. When the child burns her hand in the fire, people look at her. When the hunter comes back with a gash from a flint edge that slipped, people look at her. When the old man’s joints seize and he can’t straighten his back in the cold morning, people look at her.

She opens the pouch.

She Placed Her Hands

Go back to Shanidar. Go back to that dark cave in the Zagros Mountains, forty-five thousand years ago, where a man with one arm and one eye is lying on a bed of grass and hide, his ruined body radiating pain that never fully stops.

Someone is with him. Someone has always been with him, for as long as he can remember. She smells like smoke and crushed leaves. Her hands are rough and warm and sure. She’s pressing something against the inflamed joint of his shoulder — a poultice, wet, faintly bitter, that makes the heat recede just enough for him to breathe.

She doesn’t know the word salicylic acid. She knows the tree it comes from, the river where it grows, the season when the bark pulls cleanest, and the face he makes when the pain starts to let go.

That’s medicine.

It didn’t begin in a laboratory. It didn’t begin in a university. It began in a cave, with a woman’s hands and a leather pouch full of plants, and a patient who would have died a hundred times over without her.

Every doctor who has ever lived is her descendant.
