Today in history – May 1st
Today is the 110th anniversary of the first distribution to medical practitioners of the drug Aspirin.
The active ingredient of Aspirin was first discovered from the bark of the willow tree in 1763 by Edward Stone of Wadham College, Oxford University.
He had discovered salicylic acid, the active metabolite of aspirin. Aspirin was first synthesised by Felix Hoffmann, a chemist with the German company Bayer in 1897.
Aspirin is one of the most widely used medications in the world, with an estimated 40,000 tonnes of it being consumed each year.
Colombia issued this stamp in 1999 to celebrate the Centenary of the first distribution of the drug.
