Aspirin, also known as acetylsalicylic acid (ASA), is a medication used to treat pain, fever, or inflammation. Specific inflammatory conditions in which aspirin is used include Kawasaki disease, pericarditis, and rheumatic fever. Aspirin given shortly after a heart attack decreases the risk of death.

Aspirin is also used long-term to help prevent heart attacks, ischaemic strokes, and blood clots, in people at high risk.Aspirin may also decrease the risk of certain types of cancer, particularly colorectal cancer. For pain or fever, effects typically begin within 30 minutes. Aspirin is a nonsteroidal anti-inflammatory drug (NSAID) and works similar to other NSAIDs but also suppresses the normal functioning of platelets.

Common side effects include an upset stomach. More significant side effects include stomach ulcers, stomach bleeding, and worsening asthma.Bleeding risk is greater among those who are older, drink alcohol, take other NSAIDs, or are on blood thinners. Aspirin is not recommended in the last part of pregnancy. It is not generally recommended in children with infections because of the risk of Reye's syndrome. High doses may result in ringing in the ears.

Aspirin, in the form of leaves from the willow tree, has been used for its health effects for at least 2,400 years. In 1853, chemist Charles Frdric Gerhardt treated sodium salicylate with acetyl chloride to produce acetylsalicylic acid for the first time. In the second half of the nineteenth century, other chemists established the chemical structure and came up with more efficient methods to make it.

:6975 In 1897, scientists at Bayer began studying acetylsalicylic acid as a less-irritating replacement for common salicylate medicines.:6975 By 1899, Bayer had named the drug Aspirin and was selling it around the world. The word Aspirin was Bayer's brand name; however, their rights to the trademark were lost or sold in many countries.

Aspirin's popularity grew over the first half of the twentieth century leading to competition between many brands and formulations.

Medical use
Aspirin is used in the treatment of a number of conditions, including fever, pain, rheumatic fever, and inflammatory diseases, such as rheumatoid arthritis, pericarditis, and Kawasaki disease.Lower doses of aspirin have also been shown to reduce the risk of death from a heart attack, or the risk of stroke in some circumstances. There is some evidence that aspirin is effective at preventing colorectal cancer, though the mechanisms of this effect are unclear. In the United States low dose aspirin i
