where does aspirin come from

Aspirin originally comes from the willow tree , and the modern drug is a lab‑made version of a natural willow chemical.

Quick Scoop

• Traditional source: Extracts from willow bark and leaves were used for thousands of years to ease pain and fever because they contain a compound called salicin.

• Key natural chemical: Salicin from willow is converted in the body to salicylic acid , which is the direct natural ancestor of aspirin.

• Modern twist: In 1897, chemist Felix Hoffmann at Bayer chemically modified salicylic acid to make acetylsalicylic acid (aspirin), which was gentler on the stomach and easier to use as a medicine.

• Today’s aspirin: The aspirin in your medicine cabinet is synthetic —made in factories from chemical starting materials—but its origin story traces back to willow bark remedies used in ancient Sumerian, Egyptian, Greek, and other traditional medicines.

In short: people first chewed or brewed willow bark for pain, scientists isolated and refined its active ingredient, and chemists then transformed it into the modern aspirin tablet used worldwide.
