is that oil made from snakes?
Nope, just like Baby Oil is not made from Babies,(Wikipedia says -) Snake oil is a fraudulent liniment without snake extract. Currently, it has come to refer to any product with questionable or unverifiable quality or benefit. By extension, a snake oil salesman is someone who knowingly sells fraudulent goods or who is a fraud, quack, or charlatan.
