How Coffee, Chocolate and Tea Overturned a 1500-Year-Old Medical Mindset

When Italian botanist Prospero Alpini trafficked to Egypt in 1580, he detected a universe of surprising plants—strangely done bananas, splendid red drug poppies, corpulent baobab trees. After returning to Europe 3 years later, Alpini publicized his commentary in dual volumes, De Plantis Aegypti and Da Medicina Aegyptiorum. Among their illustrations and descriptions of a opposite flora of a Middle East and North Africa were observations of a rare plant: a coffee bush.

This plant would not customarily find a approach into daily rituals opposite Europe—it would invert a millennia-old medical mindset.

“The Arabians and Egyptians make a arrange of mush [hot brew] of it, that they splash instead of celebration wine; and it is sole in all their open houses, as booze is with us,” wrote Alpini, whose papers done him a first European to report Egyptian medical treatments.

Alpini and other physicians quickly began perplexing to report a impact coffee had on health. But doctors struggled to know a effects of coffee and dual other newly alien beverages— chocolate and tea. All of these arrived around a same time in a mid-16th century. Chocolate was described by European travelers to South America; tea from those who trafficked to China; and coffee came from North Africa, as Alpini described. As general commerce grew via a 16th and 17th centuries, direct for all 3 exploded.

These outlandish beverages presented physicians of a day with a poignant problem: How did they fit into a accepted medical speculation of a time, a humors?

The judgment of humors stretches behind to Ancient Greece. Writers including Hippocrates and Galen believed a tellurian physique was stoical of 4 humors, or fluids: blood, phlegm, black bile and yellow bile. The pivotal to this pseudo-medical complement was balance. Every individual, a meditative went, had a singular humoral composition—and if their physique fell out of equilibrium, illnesses befell them.

Medicine during a time, therefore, was greatly personal, writes David Gentilcore in Food and Healthy in Early Modern Europe: Diet, Medicine and Society. “Foods like cheese and booze competence be converted into nutritive dishes in some bodies,” he writes, “but could be poisons in others.”

According to Galen, a initial approach physicians would provide illness was with food; medicine and cauterizing were a final option. Every food had a possess humoral affiliation, that altered somewhat formed on credentials (if it was baked or spiced). Foods could be hot, cold, dry or moist, with any evil mapping onto a fluids of a body. Galen’s famous content On a Power of Foods personal dishes formed on their humoral powers, withdrawal a roadmap for destiny physicians. The book enclosed recipes, “because Galen believed that a good alloy should also be a good cook,” writes translator and historian Mark Grant.

The approach this worked in use was that doctors would allot specific dishes to adjust their patient’s humoral balance. So if someone displayed too most heat—a fever—they competence accept a bloodletting diagnosis and be educated to eat cold foods, like salad or vegetables. If a chairman gifted indigestion from eating too much, they could take a prohibited and dry prescription, like peppers and wine.

But as general trade stretched pantries and palates opposite Europe, physicians clashed over how to specify mixture that weren’t described in Galen’s work. “As we have some-more and some-more of these new things, by perplexing to fit them in, we raze a aged complement from a inside,” says Mary Lindemann, a highbrow of story during University of Miami and a author of Medicine and Society in Early Modern Europe.

Sometimes physicians were some-more successful, quite if a New World dishes were identical adequate to those already existent in Europe. Finding New World beans to be tighten adequate to European beans, and turkeys to be not distant off from informed peacocks, Europeans reserved them a same humoral properties as their Old World counterparts.

But coffee, tea and generally chocolate valid some-more troublesome. All 3 were dietary chameleons, ostensible to change in form and peculiarity during will. “Some people contend [chocolate] is fatty, therefore it’s prohibited and moist,” says Ken Albala, a highbrow of story during University of a Pacific and author of Eating Right in a Renaissance. “But other physicians say, if we don’t supplement sugar, it’s sour and astringent, so it’s dry and good for apathetic disorders. How can something be both dry and wet or prohibited and cold?”

The same debates happened with coffee, Albala says. Some physicians noticed a splash as carrying a heating effect. Others claimed coffee cooled a physique by drying adult certain fluids (an early confirmation of coffee as a diuretic). All 3 drinks—chocolate was customarily consumed as a beverage—were astringent, though if churned with sugar, their season was richer and some-more pleasant. Were they medicinal in all their forms, or customarily some? The answer depended mostly on a physician.

The discuss continued as coffee houses sprang adult opposite Europe and chocolate became even some-more renouned as a beverage. In 1687, Nicolas de Blegny, medicine and pharmacist to France’s Louis XIV, wrote a book on a “correct” use of coffee, tea and chocolate to heal illness. In it, he uttered his distrurbance during physicians who personal a qualities of a beverages differently formed on a diseases they wanted to treat.

If one piece could heal any illness, what did that contend about a rest of humoral theory? As new medical paradigms began entering physicians’ evidence wording in a 17th century, humoral speculation began to tumble apart. Some doctors now looked during a physique as a array of automatic parts, wise together like a well-oiled machine. Others saw it in terms of a chemistry.

But tradition is a realistic thing. For decades, copiousness of doctors continued to pull on humors for their medical practice. “Doctors persisted in gripping a Galenic humoral complement and resisted people who argued opposite it,” Lindemann says. “In niggardly terms, it’s a matter of people preserving their medical monopoly. It’s also substantially a matter of conviction.”

In a 19th century, countless discoveries struck a final blow to a humoral system. Physiology and anatomy advanced. Disciplines like pharmacology began questioning how drugs influenced a body, and a find of microorganisms revolutionized how doctors noticed illness. With a invention of some-more absolute microscopes, they could suppose about how germ competence interrupt a healthy body, destroying a idea that an imbalance of humors was a source of disease.

Humors might have died with complicated medicine, though their bequest did not. Even today, they’re manifest in aphorisms like “starve a fever, feed a cold” and in certain herbal remedies. As for a medicinal values of chocolate, coffee and tea—whether chocolate helps us lose weight, tea stimulates a metabolism, or coffee is healthful or harmful—we’re still arguing over that too.
