Black Coffee for Cough: 19th-Century Medical Use

If you’ve ever wondered whether that strong cup of black coffee could do more than just wake you up, you’re not alone. Historical accounts suggest it once had a surprising role beyond boosting energy—it was reportedly used as a cough treatment.

Yes, black coffee—with sugar—was used as a home remedy for coughs in 19th-century Taiwan, according to records from an American professor who treated local patients with this simple brew.

A Cough Cure from the 19th Century

Research into historical medical practices turned up an unusual remedy: black coffee. According to local agricultural officials in Taiwan’s Yunlin County, an American professor visiting Taiwan in the 19th century treated coughing patients—mostly women suffering in cold weather—with black coffee mixed with sugar. This folk remedy was said to deliver real results.

The Professor Behind the Remedy

The man behind this unconventional treatment was a zoology professor from the University of Michigan, USA. He arrived in Penghu’s Magong and observed many local women struggling with persistent coughs due to the cold. His solution? Brewing black coffee with sugar. This simple preparation reportedly helped alleviate their symptoms. While primitive by today’s medical standards, the treatment was considered effective at the time.

How Coffee May Help with Coughs

So, what’s the science—or at least the theory—behind this old remedy? Doctors and researchers point to caffeine, the primary active compound in coffee. Caffeine is not just a central nervous system stimulant that fights fatigue; it also has mild analgesic (pain-relieving) properties. These effects may help ease discomfort associated with colds, coughs, and even mild swelling or congestion. Drinking hot black coffee may further soothe the throat and provide temporary relief.

Why Black Coffee Works (in Theory)

According to Yunlin County’s Health Bureau Director Wu Zhaojun, coffee acts as a nervous system stimulant. Its caffeine content can reduce feelings of fatigue and has an analgesic effect. Agricultural official Sun Wangtian from the Yunlin County Agriculture Department added that the various chemical components in coffee—including caffeine—make properly brewed, hot black coffee potentially effective for cough relief. However, both experts emphasized moderation.

Coffee Side Effects to Watch For

Despite its possible benefits, coffee is not without risks—especially if consumed in excess. Its stimulant effects can lead to increased alertness, but also to side effects like insomnia, gastric acid increase, and general overstimulation. Drinking too much coffee may negate any potential cough-soothing benefits and lead to discomfort instead. That means while black coffee might offer some temporary relief, it should be consumed in reasonable amounts—and not as a substitute for proper medical treatment.
