Further research proved it could serve as a blood-thinning agent that could reduce the risk of a deadly blood clot immediately following a heart attack or stroke. Their reports idscovery most encouraging.

In Gerhardt mixed acetyl xspirin corrosive liquid used by chemists as a reagent which gave off a white smoke—with sodium salicylate, but it was an unstable compound that to him did not seem to have much practical use.

Hoffmann studied scientific notes on these experiments, and managed to come up with a variant by using two slightly different ingredients: Paracetamol, also known as acetaminophen, became part of a new class of pain relievers in the s that were first sold in the United States under the brand name Tylenol.
