On the “Oil of Swallows”, Part 1: Did anyone actually use these outrageous remedies?

By Michelle DiMeo, with Rebecca Laroche

Part of the appeal of old medical remedies is that many are filled with seemingly outrageous ingredients. A recipe “For deaffnesse” attributed to Sir Kenelm Digby, Fellow of the Royal Society, required one to “Take a hare new killed, Take out the bladder in which you will still find some urine … soe pouer into each eare by degrees”. The recipe concludes by suggesting one continue to do this “for several dayes with new hares”.[1] The chemist Robert Boyle’s medical remedy book includes plenty of unsavory ingredients, including wood lice and earth worms, as well a treatment for dysentery that involves drinking baked pig’s dung.[2] This, coupled with the fact that many early modern recipe books do not show all the burns, spills and edits one would expect to find in a heavily used book, leads to the question:  did anyone actually make these recipes? If so, how’d they accomplish it?

The “Oil of Swallows” is one such remedy. An early version may be found in Thomas Dawson’s The Good Husvvifes Ievvel [Housewife’s Jewel] from 1587, which begins “Take eight Swallowes readie to flie out of the nest, driue away the breeders when you take them out, and let them not touch the earth, stampe them vntill the Fethers can not be perceiued” (fols. 50r-50v). It also requires the addition of approximately five herbs to be mixed with butter, and it eventually produces an oil that should be externally applied to aches and bruises.

The recipe continues to evolve over the next 100 years and seems increasingly less believable. By the mid-seventeenth century, “Oil of Swallows” is almost ubiquitous in recipe books; however, the number of swallows greatly increases, as do the number of additional ingredients. This may be due to certain print versions of the recipe, such as that found in Gervase Markham’s The English House-vvife (1615), which requires more than two dozen separate ingredients and as many as 20 live swallows. This example from an anonymous manuscript compiled over the late-seventeenth and early-eighteenth centuries requires over twenty ingredients and “twenty Young Quick Swallows”, showing just how complicated the recipe became:

Late-17th-Century Recipe for "Oil of Swallows"
Wellcome Library, Western MS 1795, fol. 222v 

A historian’s first instinct might be to dismiss this as a remedy that was never actually tried. After all, how did they catch 20 live birds, and how did they beat them all in a mortar without the birds flying away? However, a closer reading of how the recipe language evolved over time shows contemporaries trying to sort through these complicated issues, providing tips for how and when to capture the birds, and what to do if you can’t get enough. Dawson’s recipe, quoted above, is an early example of this.[3]

But perhaps the best evidence that the “Oil of Swallows” was used is an undeniable reference to the final product in Elizabeth Isham’s autobiographical “Rememberance”, written around 1639. Isham recalls having a recurring pain in her thigh in her early adulthood. In her closet, she found a glass jar, which, upon opening, she “thought it to be by the smell oiles of swallowes”. She deduced that it must be about 40 years old and that it was made by her great grandmother “Who was … very skillful in Surgery”. Isham’s aunt “thought it might have some virtue because it retained the sent [scent]. Being close stoped.” So Isham applied the ointment to her aching thigh and found some relief, noting that “it [came] foorth in a rednes and after weared away by de grees”.[4]

Isham’s “Rememberance” makes it impossible for us to deny that the “Oil of Swallows” was actually made, and it provides contextual information to help us better understand the recipe.  If we continue to read recipes against other available archival material, including letters, diaries, and account books, we might continue to find surprising evidence that these seemingly outrageous remedies really were tried and approved. But while Isham testifies to the use of “Oil of Swallows”, we still don’t know exactly which ingredients comprised the final product she tried. And as Rebecca Laroche will explain in Part 2 of this blog post on Thursday, the ingredients in this remedy were sometimes even stranger than just swallows and herbs…

Gumpowder? A strange little recipe for sensitive teeth…

If you go to your bathroom and check the ingredients in your well-known brand of sensitive toothpaste, you may well find that the recipe contains the active ingredient potassium nitrate. Also known as saltpetre or nitre, this naturally occurring mineral is found in foods as a preservative (e.g. corned beef), and used in fertilizer, cigarettes, blood pressure medicines and fireworks. Since medieval times it has formed one of the main ingredients in gunpowder, and it is this connection that has also given potassium nitrate a long association with teeth and gums.

Many of the seventeenth and eighteenth century recipe books in the Wellcome Library’s manuscripts include treatments for gunpowder burns, but some also proposed that gunpowder could be therapeutic. Katherine Jones, Lady Ranelagh (sister to the famous chemist Robert Boyle), recommended a ‘little gunpowder’ applied in a linen cloth to ease toothache. On one page of Anne Brumwich’s recipe book (Wellcome MS 160, p.83) we can find nine recipes for toothache remedies written in two different hands. One, ‘An aproved medecine for ye toothake’ (approved meant that it worked) required gunpowder, aniseed water and lint, mingled together to ‘make a litell thing’.

Once the sufferer had picked their tooth very clean, the recipe instructed them to push the preparation into the tooth, taking care not to allow any of the mixture down the throat.

A century later, in A Treatise on the Scurvy (1795) David Paterson introduced his fellow naval surgeons to a wonderful, and apparently unknown remedy for scurvy: during a voyage in 1784, he claimed, he had restored the health of eighty sick seamen not with lemon juice, fresh fruit or vegetables, but with the potassium nitrate extracted from the gunpowder in his ship’s stores. Paterson’s remedy was soon forgotten, until in 1828, a desperate surgeon named Charles Cameron, having used up all his supplies of lemon juice, remembered Paterson’s recipe. Cameron was stranded in the calms near the equator and he was faced with a ship’s hospital full of scorbutic convicts, less than half way through the voyage to Australia. He extracted the nitre from the powder, dissolved some of it in vinegar, and mixed some more with vinegar and lime juice. He also added a little sugar (to taste?!) The effects were ‘miraculous’.

For the Navy, if Cameron was right, this was a money-saving opportunity; nitre was cheap and did not decompose over time. In the following decades surgeons continued to experiment with different remedies for scurvy until, in 1840, the Admiralty decided to perform a large-scale experiment to determine once and for all the best scurvy remedy. Over the next four years the surgeons of sixty ships transporting fifteen thousand convict men from Britain and Ireland to Australia received crystallised citric acid, potassium nitrate, and lemon juice. Their instructions clearly forbade the surgeons from trying to cause scurvy during the voyage but if the disease did appear, the patients were to be divided into three groups, each group receiving one of the remedies. Of course, the surgeons often had their own ideas, and often altered, combined and varyed the doses according to their own personal favoured recipe. So, while Surgeon Deas mixed some nitre with lime juice and some with citric acid, and felt that both mixtures were useful, Alexander Bryson gave each group the remedies mixed in a glass of wine, water and sugar. After many of the convicts developed severe scurvy, Bryson finally decided that potassium nitrate was ‘objectionable’. The surgeons had come to very different conclusions about the value of potassium nitrate but the results of the experiment were clear; potassium nitrate was abandoned as useless, lemon juice was in for good.

In the mid 1970s, dental researchers – in laboratories this time, rather than on ships – began to report a strange occurrence: mixing potassium nitrate with toothpaste seemed to reduce dental sensitivity in sufferers.  More work confirmed the compound’s beneficial effects, but the scientists still admitted that they were unclear why it should work; being soluble, it seemed that it should simply dissolve in water and wash out of the teeth at first rinse.

Jump forward again to the present, and potassium nitrate is often used as the active ingredient in products for sensitive teeth. So we have come a long way in medical understanding since women like Anne Brumwich stuffed aching teeth with gunpowder soaked lint, or Victorian naval surgeons dosed their convicts with nitre in the certainty that it helped with scurvy, and yet nitre has proved persistent: these earlier ideas about potassium nitrate’s ability to reduce not only the pain of toothache, but the symptoms of scurvy – a disease so commonly experienced in the mouth and gums – are worth wondering about.

Gathering Ingredients For Early Modern Recipes/Herbal Remedies

By Jennifer Munroe

An entry from Mary Doggett’s receipt book from 1682 in The British Library for a “Water called Rosa Solis” includes a curious set of instructions, curious not so much for the way it explains how to make said water, but rather for the lengthy details about how to gather its ingredients:

“How to make ye Water called Rosa Solis to be gathered in the Month of June or July”:
Take this herb called Rosa Solis it growes in Meadows or Marshy Grounds and in no other places, it is of an herb color and grows very Low and flat to ye ground wth a long stalk in the midst wth six branches, springing out of ye root round about ye stalk, and wth a leaf herb color, and of main bredth and length; and when you gather it take heed in any case you touch no where but ye stalk when you put it up for ye vertue lys in ye leaf, and if you touch it it’s gon; lay it in a very clean basket for ye leaves of this herb is of great strength, vertue and nature…(BL Add 27466 f.2r)

While we might assume that early modern Englishwomen collected their ingredients from their own gardens or from neighboring natural areas, receipt books from the period do not typically say as much. In fact, it would have been entirely possible for women to purchase the ingredients for their receipts. This receipt makes it clear, though, that Doggett’s reader is expected to get them herself.

But what does this receipt tell us about the plant and the woman (or person) collecting it? I find it interesting, first and foremost, that while many receipts in Doggett’s book (and so many others) seem to take for granted that the reader will already know how to acquire and use (and will probably have on hand) key ingredients, this receipt does not. Instead, the reader learns not only where to find it, but also how to identify it once she traipses through the meadow or marsh where it grows. So, either this plant isn’t as common as it might seem, as it appears in countless receipt books in the period without such instruction, or Doggett provides these directions because she assumes that her reader has simply never gathered rosa solis before. After all, the warning about how to handle the plant bespeaks an attention to (critical) detail that one would presumably not require if one had actually picked and used the plant before. Otherwise, would one not already know to “take heed in any case you touch no where but ye stalk when you put it up for ye vertue lys in ye leaf, and if you touch it it’s gon”? Reiterating the restorative powers of the leaf, not the stalk, Doggett’s receipt insists at the end that the reader must lay the leaf ever so carefully in the basket after picking as well, as the “leaves of this herb is of great strength.”

Perhaps this receipt indicates more, though, than something about its user. It may tell us as well about Doggett, about her aspirations as a manuscript compiler of receipts. Doggett’s book is arguably itself an exercise in underscoring the authority and expertise of its author. The book is presented in beautifully rendered italic hand, elaborate in such a way as to mimic the care taken in preparing an illuminated manuscript. It is neatly ordered: first waters, then salves and ointments, followed by plasters, balsams, and then medicines for different parts of the body. What this book tells us is that Doggett was concerned with how it represented her as its knowledegable source. And so, when we read not to touch anywhere but the stalk, we are reminded of the care one should take while gathering, but we are also reminded that Doggett has likely tried this receipt herself, that she too has crossed the meadow or traversed the marsh in search of the rosa solis; and we should be grateful that she has spared us wasting our precious ingredient by not knowing that the virtue lies in the leaf, that she has done the experimenting for us.

Green sickness, red plants

By Helen King

I’ve been interested for a long time in green sickness, a condition affecting girls at puberty that involved menstrual suppression, often along with some sort of dietary ‘blockage’. The remedies for it, over the 400 or so years that it was recognised as a disease, raise all sorts of problems. For example, in the 19th century it was seen as a form of anaemia, so iron was prescribed. In the 17th century, before that level of knowledge of blood existed, ‘steel filings’ were often part of the remedy, and iron is a constituent of steel. So, how did they know to use steel? Or was this nothing to do with the iron content, but instead about steel being imagined as ‘cutting through’ the blockages?

Langham’s text. From http://www.cardiff.ac.uk/insrv/libraries/scolar/digital/healthyreading.html . Copyright: Cardiff University, used with permission.

William Langham wrote ‘The Garden of Health’ in 1597. It was based on earlier recipe collections, and I came upon it when I was thinking about using recipes to tease out what exactly was supposed to be causing the symptoms – so, if the recipe involved plants that were clearly evacuative, then this could suggest that the cause of the disease was seen as a blockage. Langham arranged plants in simple alphabetical order, rather than arranging the material under the names of diseases; but, as part of his accessibility, he also gave a list of conditions with references to the different plant entries where the reader could find out more.

Langham gives a range of recipes for green sickness. One is packed full of ‘red’ plants –

‘seethe powder of the Keyes [i.e. the ash tree] with Betonie, red Sage, red Mynts, and Magerom [marjoram] in running water from a pottell [= 2 quarts] to a quart, and drink thereof a good draught with sugar warme morning and evening’

Elaine Hobby pointed out to me that this recipe also appears in 1677 in ‘The Accomplish’d Lady’s Delight’ by ‘T.P.’ (possibly Hannah Woolley), but with ‘red Fennel’ instead of ‘red Mynts’. There was a second edition of Langham in 1633, and maybe the author used this.
So what’s all this red about? Betony, sage and marjoram often appear together in later collections as a gentle sternutatory. Red sage and betony are used against bilious attacks. Ash keys feature today on ‘wild food’ sites with the warning that they are very bitter and need to be boiled several times before eating, but what was used here was the ripe seed, dried and then reduced to powder. The ash-powder is used elsewhere for the stone (by provoking urination), jaundice and dropsy.

So maybe there’s something here about getting rid of obstructions. But to me, all this redness suggests the colour of blood, and the use of running water also makes me think that this is aimed at restoring or establishing a normal menstrual flow. How do we balance the known effects of the plants chosen, with the symbolic power of red? Comments please!
