✹ About Friday 6 September 1667 arby on 4 Sep 2020 • Link I happened to read this week that asparagus was also considered a "cure" for syphilis back then. Almost anything had the potential to be a "cure" due to the dormant phases of the disease, as Susan suggests. You eat the sparrowgrass, the syphilis went away, or so it seemed. I think mercury was somewhat effective, but it carries its own boatload of risks. Lewis and Clark carried a large supply, (and needed it) speaking of boatloads.
