"In the Seventeen-Hundreds, people used willow bark to reduce a sick person's high body temperature. In Eighteen-Sixty, researchers at the Bayer Company in Germany copied the salicylic acid found in willow bark. They created acetyl salicylic acid. They called it aspirin, for the spirea plant which also contains the natural chemical. Aspirin first was made into its present pill form about one-hundred years ago."
