In 400 B.C. asprin was identified as a pain reliever.

Did You Know That:
In 400 BC, Hippocrates made a tea from the yellow leaves of the Willow Bark Tree for the relief of pain.
It wasn't until the 1800s that scientists discovered what was in the willow train that relived pain. A German Chemist produced a stable form of acetylsalyic acid, more commonly known as aspirin in 1897.
