An Ageless Remedy

With all the new drugs on the market to cure whatever ails you, it's strange to think that the No. 1 pain reliever is still aspirin, a natural drug that's been in use since 5 B.C.

According to the U.S. Food and Drug Administration, aspirin is so potent that researchers are still coming up with new uses for the substance extracted from willow bark.

So the next time you reach for that bottle of aspirin, pause to consider its staying power.
