How does aspirin treat headaches
Aspirin (ASA) was commonly thought to enter the brain through the bloodstream. There, its chemical components affect the brain and stop pain in any part of the body.
But aspirin can not be considered as a painkiller. It has been found that when a part of the body is swollen or painful, aspirin works only there. It has no effect on any other part.
How aspirin finds the site of pain has long been a mystery. In the 1970s, research revealed that the main function of aspirin is to slow down the production of a type of fatty acid called prostaglandin in the body's cells.
This hormonal prostaglandin is a warning system of the body. If any problem occurs anywhere in the body, it causes pain and irritation there. Sometimes, it can even cause a fever within the body.
Aspirin simply targets the affected cells and inhibits the production of prostaglandins there. It relieves pain, reduces swelling, temporarily stops fever, but does not eliminate the cause of the disease.
