Aspirin is an antipyretic and rheumatic that is used to allay fever, headache, arthralgia, acticerheumatism, and rheumatoid arthritis, toothache and dysmenorrhea and as raw material for making anti-carcinogen.

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 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.
