Word History: The English word aspirin comes from the German trademark Aspirin, which is made up of elements from an obsolete German term for acetylsalicylic acid, acetylierte Spirsäure, literally, "acetylated Spiraea-acid." Acetylsalicylic acid was first isolated in a species of meadowsweet, Filipendula ulmaria, which was formerly classified in the genus Spiraea, the genus that includes many of the garden plants called spirea.

Did You Know? The forest may not look like a drugstore. Nevertheless, plants have always provided humans with powerful medicine. For example, we no longer eat the bark of willow trees when we have headaches, but for thousands of years, people in pain did just that. About 100 years ago, scientists studying willow bark figured out how it could be used to make acetylsalicylic acid, better known as aspirin. Aspirin and willow bark get broken down in the stomach to supply us with the same powerful painkiller. Quinine, which people use to control the fevers of the disease malaria, originally came from the cinchona tree. Just recently, researchers developed a new cancer drug, taxol, from the needles of yew trees. In fact, about 45 percent of all cancer drugs are either natural products or slightly altered natural chemicals that scientists tinkered with to make more potent. Researchers still study traditional plant remedies in the hopes of finding even more medicines from nature.
