Aspirin (and heroin) used to be trademarked by Bayer
Along with Heroin, Aspirin was a trademarked name that the Friedrich Bayer & Co. registered in 1899. However, when the United States entered World War I against Germany, the company's U.S. assets were seized, and their trademarks were auctioned off and purchased by a private company two years later. Obviously the two drugs took wildly different paths after that.
The kicker? Heroin was synthesized by Felix Hofmann, the same guy Bayer says invented aspirin.
It used to be totally cool for kids to take it (but they really shouldn't, ever)
Back in the old days, kids were given aspirin on the regular. However, a connection was made between kids taking aspirin for chicken pox or influenza and a serious condition called Reye syndrome, which can result in seizures, brain swelling, brain damage, or coma -- and that's just part of the constellation of troubles that strike kids who are affected. There's no cure for the condition (only supportive treatment), so experts advise that parents abstain from giving their kids aspirin unless they're being carefully monitored by a physician.
