Etymology
The term originated in the late 19th-century United States, directly referencing the fraudulent liniments and potions sold by traveling "medicine shows." These products were often marketed as containing oil derived from snakes, particularly the Chinese water snake, and were falsely touted as miraculous cures for ailments like arthritis and rheumatism. The literal combination of 'snake' and 'oil' thus became a byword for any worthless, deceptive cure. Over time, its meaning expanded metaphorically to describe any product, idea, or service that is deceptively promoted as effective but is fundamentally worthless or fraudulent.
