> THESE PILLS WERE the pride and joy of Dr. Benjamin Rush, one of the Founding Fathers and a signer of the Declaration of Independence.

A later descendent of Dr Rush would go down in infamy for a foolhardy escapade to the Titanic in a carbon-fiber submersible called Titan.

> Dr. Rush’s style of “heroic medicine” had caused his star to fall quite a bit by this time — especially after the Philadelphia yellow fever epidemic of 1793, when his patients died at a noticeably higher rate than untreated sufferers.

Seems familiar...

"600 giant pills that the men called 'thunder-clappers,'"

I love little reminders that people haven't changed that much over the centuries

Hunter-gatherer tribes probably had some natural laxative they called some version of "thunder-clapper" and giggled as they said it.

I bet.

I just got back from backwoods camping, each site has a wooden chest/thunderbox/toilet out in the open woods near the site. I'm not sure if the thunder is the heavy wooden lid closing or the noises that come from it. Some are out of sight of the campsite but ours was only 75ft away, fortunately the lid blocked your view if it was in use.

I could be wrong, but I don't think that is the thunder the "thunder clappers" was named after.

'The main active ingredient in “thunder-clappers” was a mercury salt.'

This doesn't seem particularly safe or good for the environment.

I doubt if the product is sold now.

Travelling thousands of miles overland, in constant fear of ambush from a fearsome plains tribe war party, alternating between intense constipation and explosive diarrhea - bet they didn't put all that on the brochure when they were signing folks up to paddle the canoes.

Here is an article that actually describes the search for the mercury in the laxatives: https://www.discovermagazine.com/following-lewis-and-clarks-...
