Small, faded, black and white box cover for Piso's Tablets. Piso's tablets were marketed as a remedy for a wide range of ailments, including "diseased womb," dyspepsia, kidney disease, neuralgia, leucorrhea, backache, lumbago, headache, disordered menses, constipation, and urinary troubles. Early iterations of this medicine included cannabis and chloroform among its ingredients. Over time, it evolved, shedding its opiate content and, eventually, its alcohol and cannabis components. Its reign effectively ended shortly before World War II. A laboratory analysis revealed that Piso's ingredients consisted of dried alum, dried borax, boric acid, and water. Interestingly enough, these were the exact ingredients in another Piso's product called Micajah's Medicated Uterine Wafers.
