This takes a look at the little wonder pill that has proved itself again and again as the world's most successful drug.

Starting who knows when as someone first chewed a willow leaf and found it eased pain until it became a much-maligned pharmaceutical, this is an interesting story to be told.

It involves long, hard and ignored research, rivalries and victories. Wrapped up in the story is industrialism, World War I, advertising and Nazis!

Also in the story is the growth of ibuprofen and acetomenophen, and the recovery of aspirin as a heart drug. As the story ends, the hope is held out of using aspirin for cancer and other uses.
