Glass bottle containing dark brown liquid with a stained label for Hadacol Dietary Supplement. This concoction was created by Louisiana State Senator Dudley J. LeBlanc. Although he had no medical or pharmaceutical training, LeBlanc began creating patent medicines in 1938 when he founded the Happy Day Headache Powder Company. Described as a "Dietary Supplement", Hadacol contained about as much alcohol as a bottle of wine which made it very popular in dry counties. Promotion for the product included radio testimonials, fliers, a popular song called the "Hadacol Boogie," a "Captain Hadacol" comic book, and the popular traveling Hadacol Caravan Show.
