Application
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.
