“Latin for 'our own' became English for 'snake oil' — because every quack doctor insisted their secret remedy was exclusively theirs.”
Latin nostrum means 'ours' — the neuter form of noster. When a Roman physician prepared a proprietary remedy, he might call it nostrum remedium — 'our remedy,' emphasizing that it was his own formulation, not something borrowed from another healer. The word entered English in the early 1600s, initially without negative connotation.
The problem was that every charlatan also claimed to have a nostrum. The traveling medicine sellers of the 1700s and 1800s — men who sold bottles of colored water from the backs of wagons — always insisted their product was special, proprietary, their own. 'Our remedy' became code for 'we won't tell you what's in it.' The secrecy that once implied expertise began to imply fraud.
By the 1800s, nostrum was firmly pejorative. When the American Medical Association began its campaign against patent medicines in the early 1900s, nostrum was the word they used most often. Samuel Hopkins Adams' exposé series 'The Great American Fraud' in Collier's magazine (1905-1906) repeatedly denounced nostrums — the proprietary remedies that contained alcohol, opium, or simply nothing at all.
Today, nostrum means a pet solution or a quack remedy, usually applied to political or economic proposals. A politician's nostrum for unemployment. A pundit's nostrum for social decline. The word has left medicine almost entirely, but it carries with it the memory of wagons, bottles, and promises that something exclusively 'ours' will fix everything.

Every generation has its nostrums — the confident, proprietary solutions offered by people who insist they alone have the answer. The word has survived because the phenomenon never disappears. There is always someone selling something secret and claiming it works.
The Latin is honest about what nostrums are. They are 'ours' — not yours, not universal, not tested. Just ours. Buyer beware.
