We all know that cough medicine can be a lifesaver when you’re feeling under the weather, but have you ever wondered what was in those old-timey remedies?

That’s right, a real 19th-century advertisement for cough medicine touted the benefits of its “special” ingredient.

While it may sound absurd (and downright dangerous), it’s a reminder that we’ve come a long way when it comes to medicine. So the next time you’re feeling sick, be thankful for modern medicine and steer clear of any cough syrups that promise a little something extra. Trust us, it’s not worth it.
