Chloroform Cough Syrup
Somehow, this ad for cough syrup was allowed around the world. Cough syrup is fine, but it’s the ingredients in this one in particular that make it horrible, and that’s Chloroform. We’re not sure who took chloroform for coughs, sore throats, bronchitis, and diseases of the lungs, but it was a thing back then. That’s something better left in the past (via Pharmacy Techs).
