A treatise concerning the properties and effects of coffee

A mid‑century medical treatise offers a surprisingly thorough look at coffee’s place in everyday life, blending scientific observation with the economic concerns of an expanding empire. Its author, a physician attached to London’s Chelsea Hospital, writes with the confidence of a scholar who has already published on tropical disease and military health. The fifth edition, updated with fresh data and footnotes, still carries the same meticulous style that marked its earlier printings.

The work argues that coffee delivers tangible health benefits while also serving as a catalyst for social stability and colonial prosperity. It outlines how the drink’s cultivation can revive underused lands, provide modest capital for small‑scale planters, and support the growth of “useful inhabitants” in the West Indies. By linking personal wellness to broader political advantage, the author makes a case for coffee as both a daily tonic and a strategic commodity.

Listeners will hear a voice from the 1790s that treats coffee as a medicine, an economic engine, and a tool of empire, offering a rare glimpse into the era’s blend of science, commerce, and colonial policy.
