A valueless or fraudulent cure, remedy, or solution. (Often used in the phrase "snake oil salesman," one who sells or promotes such a product.) My mom keeps giving me all of these hippie-dippie pills to help my migraines, but I think they’re just snake oil, honestly.

Snake oil is something which is sold or presented as a cure or a solution to a problem but which, in fact, has no use or value. Do vitamins really help the skin or are cosmetic companies simply promoting the latest in snake oil? Note: You can also describe someone as a snake-oil salesman, meaning that they try to sell you or persuade you to believe in snake oil. Smooth-talking snake-oil salesmen use the telephone to take money from the foolish and the greedy and then vanish. Note: In the United States, snake oil was a substance typically made from the plant snakeroot. Dishonest salesmen tried to persuade people to buy it, claiming that it was a medicine which would cure their illnesses.
