Good idea. Also, even better idea if they don't list ingredients in the stuff (you don't want them to get any strange chemical you've never heard of, "Propolene Glycol? what the heck is that?"). Nothing better than just good ole Eich Too Oh.
But then again if you got it in a petstore it could just be overpriced glycerin in a bottle. (we humans can eat that stuff fine, but dunno about snakes).
But yeah, chucking sounds like a good idea.
