Aspirin is one of the world's oldest，least costly and most widely used drugs．It makes people feel better．[11] It is a common treatment for headaches，colds and flu．It also reduces other kinds of pain，such as pain in bone joints．
A drug like aspirin is said to have been used in ancient Greece．More than 2400years ago，Hippocrates told his patients to ease pain by chewing the outer covering of the willow tree．The coveting，called bark，contains the chemical salicylic acid．
In the 1700s，people used willow bark to reduce a sick person's high body temperature．[12] In 1860，researchers at the Bayer Company in Germany copied the salicylic acid found in willow bark．They created aspirin．Aspirin first was made into its present pill form about 100 years ago．
[13] In 1982，British scientist Sir John Vane shared the Nobel Prize in Medicine in part for discovering how aspirin works．He found that aspirin blocks the body from making natural substances，some of which cause pain and the expansion of damaged tissue．
