A Treatise on Tobacco, Tea, Coffee, and Chocolate

In Short

This work serves as a skeptical medical examination of the four "exotic" commodities that began to define European social life in the 1600s: tobacco, tea, coffee, and chocolate. By applying the principles of period chemistry and observation, the text critiques the health claims surrounding these substances. It is a polemic against global trade, urging readers to return to native, reliable remedies. The book has endured as a fascinating record of early globalization, capturing the panic and curiosity that these transformative, mind-altering substances sparked in the European medical imagination.

The Story

The narrative arc begins with an appeal to caution. The reader is presented with the idea that the physical constitution of a person is fixed by their native geography, making the consumption of foreign, distant substances inherently suspicious. The discussion opens with tobacco, relying on earlier historical descriptions to paint a picture of a plant once used by indigenous peoples for medicinal purposes, but now abused by Europeans for a "narcotic" high. The author argues that while tobacco may serve a purpose in specific, limited medicinal contexts—such as addressing catarrhal issues in autumn—its habitual use is a "barbarous custom" that stupifies the nerves and destroys the tone of the brain.

The focus then shifts to the mysteries of tea, which the author approaches with intense scrutiny. He presents anecdotal reports from travelers describing the virtues the Chinese attribute to tea, such as curing gout and preventing fatigue. However, he quickly pivots to a radical, skeptical conclusion: that the European Chamelæagnus (or Myrtus Brabantica) is essentially the same species as the prized Asian tea. He suggests that the "miraculous" benefits Europeans seek in expensive imports are actually available in their own backyard. He further alleges that the tea arriving in Europe is often stale, adulterated, or mixed with local leaves, rendering the entire trade a form of fraudulent profiteering.

The argument continues into the realms of coffee and chocolate. Regarding coffee, the author draws on reports of Persian and Egyptian customs, warning that excessive consumption of this "hot" drink leads to sterility and exhaustion of the vital spirits. He views the adoption of these habits as a sign of cultural decline, echoing ancient warnings that societies which abandon simple, local diets for exotic luxuries invite their own physical and moral ruin.

As the work concludes, the author brings these observations together into a broader critique of contemporary medicine and commerce. He dismisses the "fulsome exaggeration" of the Chinese who claim these plants can prolong life. Instead, he advocates for a return to the wisdom of antiquity and the use of native, fresh simples. The final pages shift from medical warnings to a technical appendix, offering detailed copper-plate illustrations of Chinese tea utensils. This inclusion serves as a final, ironic touch—a meticulous study of the very foreign culture he has spent the entire volume warning the reader to avoid.

How It Unfolds

The medical premise The text establishes that different human constitutions require specific, localized treatments. It sets the stage by arguing that foreign substances, arriving corrupted by long voyages, are fundamentally ill-suited to European bodies.

The indictment of tobacco The author provides a detailed, often vivid description of the tobacco plant’s physical properties. He concludes that its narcotic sulphur creates a dependency that dulls the senses and harms the stomach, marking it as a dangerous vice rather than a cure-all.

The botanical challenge The book pivots to tea, questioning its exotic status. By comparing the scent and physical structure of Chinese tea leaves to the native European Chamelæagnus, the author asserts they are botanically identical, framing the tea trade as a costly deception.

The cautionary tale of coffee and chocolate The narrative moves to these darker stimulants, warning of their potential to emasculate the consumer. The author links these drinks to foreign customs he views as decadent, urging European readers to resist the urge to mimic these habits.

The final judgment The work closes with a stern plea for moderation and a return to the natural order. It leaves the reader with a set of technical drawings of tea equipment, providing a strange, clinical conclusion to a heated argument against consumption.

The People

Simon Paulli stands as the central, guiding intelligence of the book. He is a man of the seventeenth-century medical tradition, deeply invested in the humoral theory of medicine. He wants to save his readers from the physical and financial ruin of "exotic" habits, but he is constantly blocked by the widespread public infatuation with these new, stimulating commodities. He emerges not as a dispassionate scientist, but as a moralist who views the trade of these plants as a form of foreign fraud.

He relies heavily on the reports of travelers like Gulielmus Leyl, whose accounts of the East Indies provide the raw data for the book's claims. Leyl acts as an envoy of the "foreign" perspective, describing tea-drinking habits with a sense of wonder that Paulli subsequently dismantles.

Finally, the reader is positioned as the primary figure of concern. Paulli treats the reader as a vulnerable patient, someone susceptible to the "avarice of apothecaries" and the deceptive marketing of imported drugs. By the end of the text, the reader is invited to become a more skeptical consumer, one who realizes that their health is better served by the humble, local shrub than by the glamorous, expensive leaf from across the globe.

In Its Own Voice

"As Tobacco is hot, dry, unctuous, and penetrating; it must, on account of these Qualities, soon take Flame: And, as it is possessed of an highly narcotic Quality, it, by its narcotic Sulphur, stupifies those who use it, corrupts the Temperature of the Brain, and destroys its Tone."

This passage summarizes the core medical argument against tobacco, detailing why the author believes it is harmful to the nervous system.

"I intreat every Lover of Truth, to throw the Leaves, (not the Shrub, Flowers, or Seeds) of the European Chamelæagnus, which, when dry, have no Scent upon live Coals, and do the same with an equal Quantity of Chinese Tea, tho' in different Rooms, and by the exact Resemblance of the Smell diffused by each, he will be convinced that the Chamelæagnus is a Plant of the same Species with Tea."

The author proposes this sensory experiment to prove that local plants are identical to the expensive tea imported from the East.

What It's Really About

At its heart, this book is an early, impassioned critique of consumer culture and globalization. The author is obsessed with the idea of "purity"—the purity of the body, the purity of medicine, and the purity of the state. He views the expansion of trade routes as an intrusion of corruption into the local, stable life of Europe. The questions he raises are existential: Does the health of a person depend on the soil they were born in? Can a society survive when it adopts the habits of its distant neighbors? He frames the adoption of tea and coffee not merely as a change in diet, but as a dangerous shift in the biological and moral composition of the European citizen.

Why Read It Today

Readers with an interest in the history of science, botany, or the rise of global commerce will find this book deeply rewarding. It provides an unfiltered window into the 1700s, where the line between medicine, moral philosophy, and superstition was remarkably thin. You will feel the author's palpable frustration with a world that is moving too fast and becoming too interconnected.

The prose can be challenging; it reflects the dense, syllogistic structure of period academic writing and relies on the humoral theories that were standard in the author's day but are now obsolete. However, there is a warmth in the author's concern for his readers—a genuine, albeit crotchety, desire to protect them from what he perceives as a global scam. You will likely walk away from this book reflecting on our modern obsession with "superfoods" and the persistent human desire to find salvation in a bottle, a leaf, or a bean. If you enjoy texts that are as much about the anxieties of their time as they are about the subjects they claim to analyze, you will find this work an essential, if eccentric, piece of history.
