The trade name “aspirin” was invented for the drug in the 1890s by the Bayer Drug Company in Germany.
The name “aspirin” is the trade name of the drug based on the chemical salicin, properly known as acetylsalicylic acid. These chemists, Brugnatelli and Fontana, determined that the active chemical that was responsible for the medicinal characteristics in the willow bark was the chemical salicin, which is the active ingredient of today’s aspirin. Several decades later, further studies on the medicinal value of the willow bark were being conducted by two Italian scientists. In 1763, Stone presented his findings to the British Royal Society. His tests demonstrated that this pulverized willow bark was effective both in reducing high temperatures and in relieving aches and pains. He obtained some, pulverized it into tiny pieces, and conducted experiments on its properties. Stone decided to test the effectiveness of the willow bark. To Stone, this particular bark seemed to have much in common with “Peruvian Bark,” which had been used medicinally since the 1640s to bring down fevers and to treat malaria. In that year, Englishman Edward Stone noticed a distinctive bitter flavor in the bark of the willow tree. Aspirin’s origins go back at least as early as 1758.
