Snake Oil

In North America the term snake oil is what we call someone selling something fake or a product that is dubious or ineffective or has made exaggerated claims about the quality or benefit.... so I laughed when I saw these stands selling snake oil.... At first I thought these jars were being sold as a snack but apparently snake oil is a traditional Chinese medicine for treating joint pain. Whether the snake oil works or not on the old joints doesn't really matter because having the snakes in jars, instead of slithering around, would mean that I would feel a lot better about walking around to give my joints a stretch...
