White willow

Salix alba

Medicinal herbsHarvest

Riverside tree whose bitter bark is the folk parent of aspirin, used for dull inflammatory pain.

Salicin and related phenolic glycosides convert in the body toward salicylic acid. Onset is slower and gentler than a tablet of aspirin, and the dose is harder to know. Same family cautions apply: bleeding, stomach lining, children with viral illness (Reye risk).

Flavor

Aspirin-bitter bark with a green willow astringency.

Parts used
