History of Medicine
The first almanacs consisted of a astrological calendar, showing the days on which therapeutic blood-letting should not be performed. By the eighteenth century they often included brief articles of health advice. In the early nineteenth century, pharmaceutical manufacturers began to buy advertising space in these popular and widely circulated publications. In 1843, C.C. Bristol of Buffalo, N.Y., brought out its own almanac to advertise Extract of Sarsaparilla. This precipitated a flood of almanacs published by pharamceutical companies. By the late nineteenth century, they had evolved into colorful and heavily illustrated works, displaying catchy and clever cover art.
