Description
This clear glass, rectangular medicine bottle bears the bold embossing: “Dr. W. B. Caldwell’s Syrup Pepsin” on the front, with “Monticello, Illinois” on the reverse. Syrup Pepsin was marketed from the late 19th century into the 20th century as a family laxative and digestive aid, advertised as “pleasant to take, safe for children, effective for adults.”
The active ingredients often included senna (a stimulant laxative), pepsin (a digestive enzyme), and sugary syrup as a vehicle. It was widely advertised as a remedy for constipation, indigestion, and “stomach troubles.”
Condition
Glass intact, no major cracks or chips.
Some light haze and residue inside.
Embossing crisp and legible on all sides.
Finish (lip) intact, typical for early 20th-century machine-made bottles.

Historical context
Dr. William B. Caldwell (1845–1922) began promoting Syrup Pepsin in the 1880s. The product became one of the most widely sold laxatives in the United States. Heavy marketing emphasized its safety for the whole family, contrasting it with harsher purgatives of the day.
Caldwell’s product survived well into the 20th century, transitioning into a legitimate pharmaceutical brand. Monticello, Illinois, where Caldwell practiced medicine and founded his company, became synonymous with Syrup Pepsin.
Curious Facts, Ephemera, and Trivia
Caldwell was a practicing physician who found fame (and fortune) through his syrup rather than clinical practice.
The company’s advertising campaigns included trade cards and elaborate posters.
Syrup Pepsin bottles are highly collectible today, often found in old dump digs due to their wide distribution.
Unlike many quack remedies, Syrup Pepsin contained ingredients that actually worked as a laxative — though dependence was a risk with prolonged use.
Excerpt
From an early 1900s advertisement:
“Syrup Pepsin — A pleasant laxative, safe for infants, effective for adults. Recommended by physicians everywhere.”
