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!
