The Greek physician Hippocrates wrote about white willow's medicinal uses in 5th century B.C.

The German company Bayer eventually created a synthetic, less harsh derivative of salicylic acid, called acetylsalicylic acid (ASA), and mass-produced it under the name aspirin. Despite this, aspirin is still known for irritating the stomach
