History is messy. If you were living in Florence or London around 1348, you weren't looking at a "learning opportunity." You were looking at piles of bodies. People were terrified because they didn't understand the Yersinia pestis bacterium. They thought the air was toxic or that God was furious. Because of that, treatments for black death during the Middle Ages were a wild, often gross, mix of religious ritual and "heroic medicine" that usually did more harm than good.
It's actually pretty wild to think about.
Imagine a doctor walking into your room wearing a heavy leather coat and a mask that looks like a giant bird beak. Inside that beak? Dried flowers, mint, and spices. They thought "miasma"—bad smells—carried the plague. Honestly, the mask was probably the most logical thing they did, even if they had the science completely backwards. It acted as a primitive respirator, though it didn't do much against the fleas that were actually jumping from rats to humans to spread the bubonic strain.
The "cure" that was actually a death sentence
When we talk about treatments for black death, we have to talk about bloodletting. This was the gold standard of medieval medicine. Doctors believed in the four humors—blood, phlegm, yellow bile, and black bile. If you were sick, your humors were "unbalanced." To fix it, they’d slice a vein or apply leeches to drain the "excess" blood.
If you already have a high fever and your organs are failing from a bacterial infection, losing a pint of blood is literally the last thing you need. It weakened the immune system and often introduced new infections from dirty blades. It's one of the reasons the mortality rate was so staggering.

Then you had the "vicary method." It sounds fake, but it's real. Some practitioners suggested plucking the feathers from a live chicken's backside and strapping the bare bird to the patient's swollen lymph nodes (buboes). The idea was that the chicken would "draw out" the poison. Naturally, the chicken just ended up dying of the plague too, and the patient stayed sick.
Lancing the buboes
Not every medieval treatment was totally insane, though. Some surgeons realized that the painful, hard swellings in the armpits and groin—the buboes—were the center of the infection. They would use a hot poker or a blade to cut them open and drain the pus.
Was it painful? Incredibly.
Did it work? Sometimes.
By draining the infection, a small percentage of patients actually recovered. But without antibiotics, most people just ended up with sepsis anyway. They’d pack the open wounds with weird mixtures like dried human excrement, crushed herbs, or even "treacle" (a sugary syrup that was supposedly aged for ten years to gain medicinal power).

What actually works today: Modern medical reality
If you get the plague today—and yes, people still get it in places like New Mexico, Madagascar, and Mongolia—you aren't reaching for a chicken. Treatments for black death in 2026 are purely about aggressive antibiotics.
The most common tools are:
- Streptomycin (the heavy hitter)
- Gentamicin
- Levofloxacin
- Doxycycline (often used for exposure)
Timing is everything. If you don't start these within 24 hours of the first symptoms appearing, the survival rate drops off a cliff. For the bubonic version, antibiotics can bring the death rate down from 60% to under 10%. For the pneumonic version (the one that gets in your lungs), it’s still an emergency. Without treatment, it’s 100% fatal. Every time.
The quarantine factor
We have to give the 14th-century Venetians some credit. They invented the trentine (30 days) and later the quarantino (40 days) of isolation for incoming ships. They didn't know about bacteria, but they saw the pattern. They realized that if you keep sick people away from healthy people, the fire eventually runs out of fuel. This wasn't a medical "cure" in the sense of a pill, but it remains one of the most effective historical treatments for black death at a population level. It's basically the foundation of modern public health.

Fragrant air and diet: The lifestyle "cures"
People were desperate. If you were wealthy, you were told to avoid "heavy" foods like meat and instead eat light soups or fruits. You were told to stay indoors and keep the windows shut to block out the "poisonous" night air.
Many people carried "pomanders." These were little decorative balls filled with ambergris, musk, and expensive spices. You’d hold it to your nose whenever you walked past a "stinky" area. While it made the walk more pleasant, it did zero to stop the Yersinia pestis bacteria from entering your bloodstream via a flea bite.
Then there was the "Four Thieves Vinegar." Legend says a group of grave robbers in Marseille were caught during an outbreak but didn't get sick because they drank and doused themselves in a special herbal vinegar. The recipe usually involved wormwood, rosemary, sage, and garlic. Modern science suggests that some of those herbs, especially garlic and rosemary, might have actually acted as a mild insect repellent. It wasn't a cure, but it might have kept a few fleas away by accident.
Actionable steps for modern safety
The Black Death isn't a ghost of the past; it’s a living pathogen. While we have the luxury of modern medicine, prevention is still the smartest move if you live in or travel to endemic areas.
- Manage your rodents. If you live in the American Southwest or other plague-prone regions, don't let rats or squirrels nest near your house. No rodents means no fleas.
- Protect your pets. Cats are especially susceptible to plague and can pass it to humans. Use vet-approved flea control and don't let them hunt wild rodents in high-risk zones.
- Know the symptoms. If you develop a sudden, high fever accompanied by a painful, swollen lump in the armpit or groin after being outdoors, get to an ER immediately. Do not wait for it to "clear up."
- DEET is your friend. When hiking in areas where plague is active, use insect repellent on your skin and clothes. Fleas are tiny and easy to miss.
- Antibiotics are the only cure. Forget the "natural" remedies you see on TikTok or historical blogs. This is a bacterial infection that requires prescription-grade intervention.
The history of plague treatments is a story of human desperation and the slow, painful birth of real science. We've moved from strapping chickens to our bodies to using targeted molecules that dismantle bacterial cell walls. It took us six hundred years to get here, but the result is that a disease that once killed half of Europe is now mostly a footnote in a doctor's handbook.
