Knill's Anti-Dyspepsia Tablets "Pepsin Compound," circa 1898

Summary

Nineteenth-century entrepreneurs promised cures with patent medicines. Some of these concoctions, however, contained harmful ingredients or ingredients used in unsafe quantities -- the industry was unregulated and manufacturers were secretive about their recipes. Beginning with the Pure Food and Drug Act of 1906, national legislation increasingly prohibited misleading health claims and required manufacturers to list their product's contents.

Specifications

Overview: In 2009, The Henry Ford conservation department teamed with Department of Chemistry and Biochemistry, University of Detroit Mercy to analyze a selection of patent medicines in The Henry Ford's collections. The purpose of this analysis was to identify the exact composition of the medicines. Armed with this information, conservators at The Henry Ford will be able to determine appropriate storage methods of the medicines and, in some instances, proper disposal methods for any hazardous materials.

Abstract: A series of patent medicines and nostrums, permanently housed in The Henry Ford in Dearborn, MI, have been analyzed by energy dispersive Xray fluorescence (EDXRF) spectroscopy and multi-nuclear NMR. Such materials were created over a century ago in relative secrecy, and thus the ingredients and recipes have never been made public. The initial findings for metals and organics in these items are presented.

Product Label: Knill's Anti-Dyspepsia Tablets "Pepsin Compound"

Possible Ingredients: Unknown

Form: Tablet

Physical Description: Surface is a dark brownish/black color, but due to moisture exposure has a blotted appearance. Flattened circular shape with a flat, band like equator. Very dense.

Size (mm): 9 x 4

Elements Present at 20.0 keV, grouped by Qualitative Peak Size: Small: Iron (Fe); Very small: Calcium (Ca), Potassium (K), Chlorine (Cl), Bromine (Br), Rhenium (Re); Detectable: Zinc (Zn), Gold (Au), Silver (Ag), Copper (Cu), Silicon (Si), Potassium (K)

Elements Present at 40.98 keV, grouped by Qualitative Peak Size: Very small: Iron (Fe), Bromine (Br); Detectable: Gold (Au), Aluminum (Al)

Method of Analysis: A combination of EDXRF and 1H NMR was used to help determine these compositions. When analyzing for a wide spectrum of elements, a semi-quantitative system was determined. A 1,000 ppm Pb standard was used to compare against peak sizes of the unknowns.
