I have as much of a sense of nostalgia as anyone. I love history. I think that there is lots to be said about the “good old days,” whenever the heck they were. I do not, however, think that the “good old days” generally include medicine.
The fact is that it’s only been about 100 or so years since medical practitioners really got their acts together and started to be able to figure out if they were actually doing anything good. Prior to that, medicine was a world of humo(u)rs and miasms, treated by bleeding, burning, and purging, plants and animal matter of all sorts (the 6th century Chinese apparently liked otter feces) and all sorts of other awfulness. In light of some of the things that were done, it’s kind of amazing that anyone survived their treatments. Mostly, people (and horses) survived in spite of the crazy things that were done to them.
Nevertheless, in those wild and wooly days of yesteryear, enterprising medical entrepreneurs turned out an endless stream of products, with some pretty fantastic claims. They designed some absolutely artistic advertising cards to go along with those claims, too. These trade cards surged onto the scene in the 1870’s, coinciding with the advent of color printing.
