From what I remember from writing an undergrad history paper on these dudes, it was used for lots of things such as a treatment for chlamydia (or another STI - I don't remember exactly). These dudes were banging their way across America, especially the black slave they brought along as apparently the locals thought he had big magic.
I'm not condoning any of this sort of colonialism - just clarifying that these dudes probably single-handedly introduced some new STIs to whole populations, and they were dragging their leaky mercury-riddled dicks along in their boats.
You're right (I didn't make the meme); mercury chloride was a historical multipurpose medicine.
Your comment is amazing, as an aside.
Thanks! Their story is interesting in and of itself (in its problematic way suited to the era), but I do try to give it my own flair.
That's some seriously radioactive shit
Nah, just chemically toxic.
If you want some radioactive shit, apparently there existed radium blankets, that would warm you up
