Acetylsalicylic acid, better known as aspirin, is well known for its properties as a nonnarcotic analgesic and anti-inflammatory drug. A derivative of salicylic acid, the drug crystallizes in the form of a white, needle-like powder with only a faint odor. It was first synthesized in 1897 by chemist, Felix Hoffmann, an employee at the BayerŽ Company in Germany to relieve his father's rheumatism. The compound later became the active ingredient in aspirin named - "a" from acetyl, "spir" from the Meadowsweet plant Spiraea ulmaria (now called Filipendula ulmari) that yields salicin, and "in," a common suffix for medications.
