Although it has recently come to our attention that constipation is as much if not more of a problem for women than men, men also have days when they need to induce gentle release—or, in the case of this product from 1936, explosive diarrhea. The happy housewife in this ad from ModernMechanix gave her husband some NR tablets, which didn't just provide "partial relief," but "thorough, cleansing action that aided in ridding his system of poisonous waste." Then she took some herself! You, too can use NR tablets when you need to shit your brains out, the stuff is now called Nature's Remedy. Or Ex-Lax. [ModernMechanix]
