Bayer actually didn't invent aspirin they marketed it(in the year 1900). Aspirin was first made in 1853 by a french chemists named Charles Frederic Gerhardt by buffering salicylic acid with sodium and acetyl chloride. This idea was lost but was rediscovered in 1899 by the German Chemist Felix Hoffmann. Felix worked for the company Bayer and had the company market it.
Chewing on willow bark is commonly practiced to relieve pain and inflammation due to its active ingredient, salicin, which is similar to aspirin. However, it is essential to consult with a healthcare provider before using willow bark, as it can interact with certain medications and may not be suitable for everyone. Overconsumption can lead to side effects such as digestive issues or allergic reactions.
In 1853.By: Zoya MobeenCharles Gerhardt invented aspirin in 1853.In 1853, Gerhardt neutralized salicylic acid by buffering it with sodium (sodium salicylate) and acetyl chloride, creating acetylsalicylic acid. Gerhardt's product worked but he had no desire to market it and abandoned his discovery.In 1899, a German chemist named Felix Hoffmann, who worked for a German company called Bayer, rediscovered Gerhardt's formula. Felix Hoffmann made some of the formula and gave it to his father who was suffering from the pain of arthritis. With good results, Felix Hoffmann then convinced Bayer to market the new wonder drug. Aspirin was patented on February 27, 1900.The folks at Bayer came up with the name Aspirin, it comes from the 'A" in acetyl chloride, the "spir" in spiraea ulmaria (the plant they derived the salicylic acid from) and the 'in' was a then familiar name ending for medicines. Aspirin was first sold as a powder. In 1915, the first Aspirin tablets were made. Interestingly, Aspirin ® and Heroin ® were once trademarks belonging to Bayer. After Germany lost World War I, Bayer was forced to give up both trademarks as part of the Treaty of Versailles in 1919.*The information above was taken from About.com's History of Aspirin(link in the related links section below)If you want a quicker answer its 1853
