Scientific Name: Salix petiolaris (sali- [L] willow; petiol- [L] stalk)
Common Name: Meadow willow
Origin: Native
Notes: Hippocrates (circa 300 B.C.) left records of effective pain treatment with a powder prepared from willow bark and leaves. The active ingredient was latter isolated and named salicylic acid after the willow genus Salix. The Bayer company made an altered version (acetlysalicylic acid) which they trademarked and named Aspirin. After World War I, the Treaty of Versailles removed the trademark protections (in certain countries) and asperin (with a small a) became a generic name.
