Back in the day, medicine didn't fool around, not even for a cough. This picture shows the alarming active ingredients in One Night Cough Syrup. I’m sure anyone that took this got their money’s worth. It would certainly stop your cough, or at least make you forget you had one. It’s nice that they assured us the alcohol was less than 1%, as if that was the scariest ingredient.
I found a legal case from 1934 involving this cough syrup, in which the FDA ruled that the claims of its therapeutic properties were misleading, and a few dozen bottles that had been shipped across state lines were destroyed.
