In the early 20th century dangerous and often poisonous chemicals were included in many common household products. Browse these pictures of medicines, liniments, moonshine and a cyanide furnace.
A 1905 cover of Collier's magazine accuses patent medicine of poisoning Americans. "Babies who cry are fed laudanum under the name of syrup," the cover reads.
Philadelphia pharmacist John B. Ferguson produced and sold "Lead Water" to soothe infant eczema, poison ivy, hives or other itchy skin rashes.
Mercury was used for medicinal purposes for centuries, and when compounded with chlorine, mercury chloride was sold as an antisyphilitic, as seen in this Squibb's pharmaceutical catalogue.
In 1927, Vigoradium advertised a water dispenser containing a small amount of radium in glass in the center, thus offering consumers "liquid sunshine" at their fingertips.
An advertisement for Radium Radia claims the product is "unquestionably the only reliable and sure cure for Rheumatism, and all other bodily pains." It is also "a sure cure for appendicitis."
Radium was considered such a health additive and miracle cure in the early 20th century that dozens of companies began branding their wares as "Radium". Radium brand cookware (pictured), "Radium Silk" neckties, and a "radium heater" were all advertised in popular magazines.
It is unlikely that Radium Spray actually contained any radium, but the combination bug killer/furniture polish was nonetheless advertised to "kill everything but a guilty conscience."
In the early 20th century, chloroform was easily available for doctors to use as an anesthetic -- or for burglars to use to render their victims unconscious.
Cyanogas, or calcium cyanide, is still used in some parts of the world as a rodenticide and insecticide, though its toxicity has made it unpopular in the U.S. In 1926, the American Cyanamid Sales Company advertised Cyanogas "to kill rats quickly, cheaply and surely."

During the 1920s Prohibition era, hundreds of Americans learned to produce homemade alcohol, commonly called moonshine.
To help enforce Prohibition, the government made denatured alcohol even more vile and toxic by adding more methyl alcohol and sometimes even kerosene and benzene.
The use of poison as a murder weapon goes back thousands of years. Forensic toxicology, however, is much newer.
In the early 20th century, the average American medicine cabinet was a would-be poisoner's treasure chest.
