this is misleading. aspirin was created by a chemist, whose father consistently got an upset stomach from powdered medicinal salicyclic acid (the precursor and degradation metabolite of aspirin in the body, thus having the same effect), in order to alleviate the side effects of what was the best pain reliever of the day (salicylic acid, of course). all he did was add another functional group (acetyl–>acetylsalicylic acid) to make the drug commonly called aspirin. so, people didn’t just go from eating bark to popping aspirin pills. we were somewhat civilized and knowledgeable in the 1800s. however, salicylic acid does come from the bark of the white willow considering it is a plant hormone; but there was a full century between bark and aspirin where pure salicyclic acid was used.
