Revisiting Erik Heinrichs’ The Live Chicken Treatment for Buboes: Trying a Plague Cure in Medieval and Early Modern Europe

Today we revisit a post originally published in 2017 by Erik Heinrichs on a seemingly odd treatment for plague buboes: the feathers from a chicken’s backside. Erik notes that there is a very long history of using chickens and chicken broths in medicine, partly because chickens are such commonly kept animals. I certainly remember being fed chicken broth when I was ill as a child, but I must say that I broke that tradition with my children. They still get ice cream though… Laurence Totelin

While researching German plague treatises I became fascinated by one odd treatment for buboes that appeared again and again, despite sounding so far-fetched. One sixteenth-century version calls for plucking the feathers from around the single hole in a chicken’s backside, then placing it on a person’s bubo. The instructions say to hold the chicken on the bubo until it dies, when it must be replaced with a new chicken, similarly plucked. I soon dubbed this the “live chicken treatment for buboes” and after years of casual encounters I began to track the recipe more systematically. As strange as it sounds, versions of this “live chicken treatment” were fairly common in plague writing, beginning with the Black Death and lasting, amazingly, into the eighteenth century. Tracing the long history of this recipe led me to explore questions such as: Where might this come from? Why chickens? Why might healers think that this was a good idea? Did anyone actually try this or is this all theoretical? As a historian, I was also interested in change over time within the recipe. Here I found much to explore, as I followed the recipe’s twists and turns over a seven-hundred year period, roughly 1000 to 1700.

The “live chicken treatment” turns out to have a long history, indeed. Its origins seem to lie in Avicenna’s Canon of Medicine, although it may be older than that. Chickens and chicken broth were a common source of medicine in early times, probably because chickens were such ubiquitous and useful animals since antiquity. Not only did Avicenna praise chicken broth for its general benefits for the body, but he also recommended placing a cut chicken on a poisonous bite or sting in order to fight poisons. In later centuries European physicians turned to Avicenna’s advice when they faced the mysterious and devastating epidemics of the fourteenth century. As Europeans emphasized the poisonous nature of the plagues around them, older treatments for poisons drew new attention. The first mention of using a chicken rump to draw poisons out of a bubo appeared in the very first plague treatise of 1348, coming in response to the so-called Black Death. Here the Catalan author Jacme d’Agramont seems to have introduced a novel and lasting adaptation of Avicenna’s recipe, although the “cut chicken” version persisted in plague treatises for centuries to come.

Most interesting for the history of trying and testing cures are the many variations of the “cut chicken” and “chicken rump” versions of the treatment, as well as physicians’ comments about how effective they are. Especially after 1400, physicians seem to be thinking about this recipe quite often as they seek practical treatments for the plagues of the time. Physicians were preoccupied with altering the recipe in order to reason out the nature of the mysterious poisons underlying the plague. Some add substances to the process, such as salt placed on top of the chicken as it is placed on the bubo. During the fifteenth century, a number of German physicians began to explain the treatment’s workings in a strikingly physical way—that the chicken breathes through its backside and thus pulls the bubo’s poisons into itself. This change led to the suggestion to hold the chicken’s beak shut during the treatment in order to force the chicken to breathe from below. My article (accessible here) show how all aspects of the treatment changed over time as physicians engaged with the recipe, including the quantity of chickens used, the amount of time required, and even the type of animal in question. This work demonstrates the importance of the recipe itself as a platform for thought, experimentation, and communication among physicians.

Perhaps a surprise to modern readers, many physicians praised their version of the “live chicken treatment,” describing it as effective and desirable. Such comments multiply after the introduction of print, which encouraged the production of plague treatises, some fitted with fetching cover illustrations for the marketplace (see image below of Philippus Culmacher’s treatise of circa 1495). In German-speaking lands especially, sixteenth-century physicians used their printed plague treatises to promote their own services and expertise at a local level.[1] This brought about a change in the genre whereby physicians seem more eager to discuss their own experiences with effective recipes in order to appeal to the practical interests of a broad audience. Amidst this change comes evidence that some German physicians witnessed first-hand the successful use of the “live chicken treatment.” Another interesting change during the sixteenth century is the increased attention to the bodily warmth of the chicken as the treatment’s active healing force. These emergent views provide a tantalizing link to modern medicine, since moist heat remains one of the treatments for buboes today. For more information, please read my article.

Revisiting Tillmann Taape’s Recipes against the plague – in pharmaceutical code?

Editor’s note: Today we revisit a post originally published in 2013 by Tillmann Taape on plague remedies given by the apothecary Hieronymus Brunschwig in his Liber pestilentialis (1500). The book included an interesting mix of recipes in the vernacular German and in Latin. Readers unable to read Latin could copy a recipe, visit their apothecary, and collect their anti-plague remedies a little while later. Tillmann’s post offers  insights into the use of Latin as a sort of code. 

It strikes me that, five hundred years on, in the midst of another pandemic, Latin has now been almost entirely replaced by English in scientific discourse. And yet, Latin still lingers on, not the least in the name of the disease that has changed our lives: corona, the crown. To this classicist, the name ‘coronavirus’ calls to mind an evil crown-wearing tyrant. But as it did in the late Middle Ages, Latin obfuscates as much as it clarifies, and I find it fascinating that, to many, the new plague, under its shortened name of COVID-19, evokes not an item of jewellery, but a family of birds: the corvids (Latin: corvidae).

Although the plague is best known for having wiped out about a third of Europe’s population in the fourteenth century, it continued to loom large as a threat to people’s health for hundreds of years, and medical writings on the Black Death or the ‘pestilence’ abounded. One of them, the Liber pestilentialis (1500) by the surgeon-apothecary Hieronymus Brunschwig (introduced here), was the first of its kind to be published as a printed book. Written in German, it had the potential to instruct a wide readership, reflecting Brunschwig’s mission to disseminate medical knowledge among laypeople. It struck me as somewhat odd, therefore, that quite a few of the recipes for remedies against the plague were given in Latin. What use were these to the readers of a book which was specifically addressed to all social ranks, including ‘common people’ who were not part of the Latin-speaking learned élite? Fortunately, Brunschwig provided an answer only a few pages on: simply copy the recipe on a slip of paper, send it off to your local apothecary, and collect your anti-plague pills a few days later.

Since Brunschwig was himself an apothecary in Strasbourg where the Liber pestilentialis was first published, one might suspect that by including these recipes he was hoping to advertise his trade, and draw attention to the knowledge and skill required to turn such coded messages into remedies. By his own admission, though, this only worked for readers who lived a manageable distance from an apothecary and could afford his services and ingredients, some of which, like theriac or amber, could be very costly. But Brunschwig also catered for those readers who lived in remote villages or were less well off. Often on the same page as the Latin instructions, he included an alternative recipe in German, using cheap everyday ingredients and simple household techniques.

This commitment to his less privileged readers, present in much of Brunschwig’s work, suggests that he was not printing recipes ‘in code’ simply in order to improve apothecaries’ image or to turn a better profit, much less to monopolise medical knowledge. There was, in fact, another very good reason for the use of Latin, as he explains in an intriguing comment: “Many recipes and ingredients cannot be succinctly expressed in the German language […], so I have left them in Latin.”

Some things are best left to professionals: mixing medicines at the apothecary's shop (from Brunschwig's 'Buch der CIrurgia')

This points to a major difficulty faced by all medical authors writing in their native tongue. They were not only up against the disdain of learned physicians who wanted to keep all medical knowledge within university walls, well away from the ignorant ‘common people’. They were also facing the daunting task of creating a scientific vernacular in which to express medical concepts: how the human body works, what happens when it becomes diseased, and what to do about it. Finding their feet on uncharted linguistic territory and creating medical terminologies was the work of generations of practitioners from the middle ages to the early modern era. By the beginning of the sixteenth century, this process had come a long way, as Brunschwig’s writing shows: in his books on surgery and distillation (see here and here), he articulates elaborate techniques and medical theories in a confident technical vernacular – albeit one peppered with terms borrowed from Latin. In the case of specialist pharmaceutical ingredients and preparations, however, Brunschwig clearly felt that no adequate vocabulary was available in German. Some ingredients were just too  specific or too exotic to be known to the layman. Perhaps even more problematic were shorthand instructions such as fiat pulvis (it shall be a powder) or formentur pillule communi quantitatis (pills of equal quantity shall be formed). One can imagine what these few words translated to in practice: complicated series of decoctions, infusions, drying, boiling, grinding and mixing, all defined and learned over the course of an apprenticeship.

With no alternative to certain elements of Latin pharmaceutical jargon, then, the recipes in Brunschwig’s Liber pestilentialis inevitably fell into two categories. On the one hand, his wealthier readers had the option of having ‘professional’ remedies made according to the Latin recipes, which allowed them to tap into the entire range of medicinal ingredients and preparation techniques available at the nearest apothecary’s shop. Poorer folks and country dwellers, on the other hand, were offered a different type of recipe which could be articulated in the vernacular, required cheaper ingredients and could be managed at home.

Revisiting Lisa Smith’s Coffee: A Remedy Against the Plague

Editor’s note: Today, we revisit a post by our editor Lisa Smith on the use of coffee as an eighteenth century cure-all against smallpox and the plague. The botanist Richard Bradley claimed that coffee would be effective in treating such diseases because it ‘lifted the spirit’. I certainly find that caffeine lifts my spirits, even if temporarily, but we know that high spirits are unfortunately no protection against COVID-19 and other viruses. Still, there is no harm in taking a break – caffeinated or not – and I hope that this post will give you good cheer. Laurence Totelin

1721, London: The plague raging in Marseilles threatened London’s busy ports. The British government took action, asking a core group of physicians to devise a plan in case the plague reached London. Smallpox was already rampant and the King had ordered a series of inoculation experiments on prisoners. Troubled times.

Enter the impecunious botanist Richard Bradley. (I discussed his interesting life in a recent blog post.) When he wasn’t in debt to booksellers, he made a living from popular medical and scientific writings, such as The virtue and use of coffee, with regard to the plague, and other infectious distempers (London, 1721). He wrote: “At this time, when every Nation in Europe is under the melancholy Apprehension of an approaching Plague or Pestilence, I think it the Business of every Man to contribute, to the utmost of his Capacity, such Observations, as may tend to the Service of the Publick.”

And in the face of the plague and smallpox he offered… coffee. Remedies prescribed by other physicians, he insisted, “are little different from each other.” Coffee, however, “is of excellent Use in the time of Pestilence, and contributes greatly to prevent the spreading of Infection.” Who knew?

Apparently the Turks. Bradley explained: “in some Parts of Turkey, where the Plague is almost constant, it is seldom mortal in those Families, who are rich enough to enjoy the free Use of Coffee.” In his treatise, he discussed coffee’s efficacy and provided (most tantalizingly for the coffee-mad Brits) “an Account of the best Method of roasting the Berries, and preserving them after roasting.”

I present to you Bradley’s instructions for preparing coffee. First, he recommended spreading out the ripe berries to dry and harden beneath the sun. The husks were then to be removed so that the berries could be toasted in an “airy place to clean them.” Finally, the berries were ready for the roaster, and this was an important step: the roasting process, Bradley claimed, would determine “the Goodness of the Liquor.” Never fear, though, Bradley had “taken some pains to experience the best Method of roasting it.” His conclusion was that the berries would be heated most equally by placing them in an iron vessel and turned on a spit over a clear or charcoal fire. His personal preference was “roasted in a middle way, not overburnt.” To modern readers, this seems like a lot of work, but Bradley reassured his readers that this process could easily be done at home, as apparently many “Persons of Distinction in Holland” did.

Making the beverage also required special equipment and techniques. To prepare the decoction, earthen or stone vessels were best, as metal spoiled the flavour. Boiling the coffee evaporated “too much of the fine Spirits”. Pouring boiling water over the powder of ground berries and infusing it for four or five minutes in front of the fire would be better and “much exceeds the common way of preparing it.” He provided an alternative, too: grinding the berries into powder, adding the powder and water into a stone or silver coffee pot and leaving the pot in front of the fire for a couple minutes. The liquid was always “thick and troubled” after brewing, but could be made “clear enough for drinking” by adding a spoonful or two of cold water to force the grounds to sink.

Coffee was worth the effort, being the ultimate cure-all. Bradley described its many virtues, which included treating head pains, vertigo, lethargy, coughs, moist and cold constitutions, consumptions, swooning fits, digestive problems, sleepiness, running humours, sores, scrofula, drunkenness, rheumatism, gout, intermitting fevers and infection. It could also purify the blood, provoke urination, stimulate the menses and deworm children. Indeed, it was particularly beneficial for menstruating women. According to Bradley, Arabian women drank coffee during their “periodical Visits, and find a good Effect”, such as contraction of the bowels and toned up genitals. Coffee was not for everyone though. Those suffering from melancholy vapours, hot brains, or paralysis should avoid it.

The reason that coffee would be so efficacious in treating infectious disease was that it lifted the spirits—and those “whose Spirits are the most overcome by Fear, are the most subject to receive Infections”. The correct use of coffee supported the drinker’s “vital Flame”, protecting the drinker from fear and despair. To gain coffee’s maximum benefits, Bradley recommended the following dosage: at least twice a day, first in the morning and at four in the afternoon.

Coffee breaks: good for your health!

Remember, remember the fifth of November

The Early Modern Recipes Online Collective transcribathon for 2019 is coming soon… November 5! Flex those fingers, boot up your computer, and get ready to join in, because this is no ordinary transcribathon.

Please join EMROC for our fifth annual international transcribathon as we transcribe an anonymous early modern medical recipe book (which includes recipes for whiskey and novel uses for oatmeal). It’s a super source, which Rebecca Laroche describes here. We will have transcription groups working in at least a dozen locations around the world, on three continents, with people coming and going virtually throughout the day.

The goal? To complete a transcription of a recipe book, making it easier for users to search than a digitised manuscript. This will eventually be available through the Folger Shakespeare’s Library catalogue alongside page images. Our other goal is to have fun with a community of people interested in transcribing and recipes, whatever their skill level.

We have lots of exciting activities planned to accompany our transcribing delights, which will run from 11:00 a.m. to 11:00 p.m. GMT.

There will be:

  • subject hashtags on Twitter: #EMROCtranscribes, #feministOED, #materialhealthtech, #animalproducts, and more. (Details on the EMROC blog.)
  • a Zoom link ( all day to connect participants from around the globe.
  • and speakers!

Joining Zoom

Zoom is an easy-to-use platform that enables participants to ask the EMROC team questions throughout the day and to chat with other transcribers. You don’t need any special tools, either. Just click on our Zoom link, download the exe (if you don’t already have Zoom), and you’ll be in. There are details here on how to join, participate, and leave. We are hoping that the chat and Q&A functions on Zoom will make it easier for novice transcribers to get help quickly, as well as to bring the transcriber community together.


The Department of History at the University of Essex is also hosting an EMROC panel on ‘Recipes in the Making’, which focuses on the manuscript we’re transcribing. Speakers include Heather Wolfe (Folger Shakespeare Library), Sara Pennell (Greenwich), and Anne Stobart (Exeter).

The panel will be recorded, though it won’t be up immediately…


We would love it if you filled in our pre-transcribathon survey, which will take no more than five minutes of your time. The survey will help us to learn more about our participants’ interests and backgrounds.

If you want to join in or have other questions, please do let me know on Twitter (@historybeagle) or by email (

Thank you so much for your interest in our transcribathon and for filling in the survey. We would be so excited to transcribe with you on November 5.
