Patent medicines, often called nostrums, were basically over-the-counter remedies marketed directly to the public, promising cures for all sorts of ailments. They were popular in the 19th and early 20th centuries. Think of them as the unregulated energy drinks of their time, often with dubious ingredients and even more dubious claims. Unlike today's medicines, they weren't tested for safety or effectiveness. Many contained high levels of alcohol or narcotics. They were pure marketing hype, preying on people's hopes and fears. They represented a time before consumer protection laws.
