It was issued by the Dr. Seth Arnold Medical Co., probably in the 1880s. It advertises Dr. Seth Arnold's Cough Killer for curing coughs, whooping cough, colds, pneumonia, asthma, croup, malaria, inflammation of the stomach, and malignant fevers as well as Arnold's Anti-Bilious Pills, which were supposed to cure liver complaints, biliousness and headache. Like many 19th century over-the-counter medicines, a lot of its effect was due to the fact that it contained a narcotic drug or hallucinogen - in this case morphine, a derivative of opium. People were unwittingly being exposed to habit forming drugs; something the American Medical Association started investigating about this time by compiling a list of dangerous ‘nostrums’ in May 1909, including alcohol, opium and its derivatives, morphine and codeine, cocaine, chloral, and cannabis. Legislation followed eventually. Dr. Seth Arnold was a doctor and a patent medicine manufacturer from Smithfield, Rhode Island. Other popular cures included Dr. Seth Arnold’s Balsam, for cholera, dysentery, diarrhoea, etc. and Soothing and Quiet cordial, for stomach and bowel problems. In 1892, Dr. Seth Arnold died leaving his sons in charge of the firm which they sold about 15 years later to Gilman Brothers of Boston, Massachusetts.
