126 years ago today, March 6, 1899 (January 25, 1899 in the lunar calendar), aspirin was approved for marketing. Aspirin is a time-honored antipyretic analgesic. It was born on March 6, 1899. As early as 1853 in the Shire, Fredrik Gerard synthesized acetylsalicylic acid from salicylic acid and acetic anhydride, but it failed to attract people's attention; in 1898, German chemist Fihoffmann synthesized it again and treated rheumatoid arthritis for his father, with excellent results; it was introduced to the clinic by Dreiser in 1899 and named it aspirin. So far, aspirin has been used for a hundred years and has become one of the three classic drugs in the history of medicine. It is still the most widely used antipyretic, analgesic and anti-inflammatory drug in the world, and it is also used as a standard preparation for comparing and evaluating other drugs. It has an anti-thrombotic effect in the body. It can inhibit the release reaction of platelets and inhibit platelet aggregation, which is related to the reduction of TXA2 production. Clinically used to prevent the onset of cardiovascular and cerebrovascular diseases. According to documentary records, it is said that the inventor of aspirin was Felix Hoffman of Germany, but a very important role in this invention was a Jewish chemist, Atul Eichingrin. In 1934, Felix Hoffman claimed to have invented aspirin himself. At that time, Germany was in the dark period of Nazi rule, and the persecution of Jews had intensified. Under such circumstances, the arrogant Nazi rulers were even more reluctant to admit the fact that the inventor of aspirin was Jewish, so they made the mistake of putting the title of inventor on Felix Hoffman alone, praising their "theory of greater German national superiority." The Nazi rulers also imprisoned Artur Eichingrin in a concentration camp to silence him. After the end of World War II, around 1949, Artur Eichingrin raised the issue again, but he died shortly after. From then on, this matter fell into the sea. British medical scientist and historian Walter Snyder obtained a license from the German Bayer Company after many twists and turns, consulted all the archives of the Bae Company's laboratory, and finally restored the historical true nature of this invention with conclusive facts. He pointed out that Artur Eichingrin was instrumental in the invention of aspirin. The fact is that in 1897, Felix Hoffman did synthesize the main substance that makes up aspirin for the first time, but it was under the guidance of his boss, the well-known chemist Atur Eichingrin, and he completely adopted the technical route proposed by Eichingrin.
