Frequently Asked Questions

Is willow bark just natural aspirin?

Not exactly. While salicin converts to salicylic acid (what aspirin is derived from), willow bark also contains flavonoids, polyphenols, and other compounds that contribute to its effects. It has a slower onset but may be gentler on the stomach than aspirin. However, it should be avoided by anyone with aspirin allergy.

Can I take willow bark instead of daily aspirin for heart protection?

No. Willow bark salicin is converted to salicylic acid, not acetylsalicylic acid (aspirin). Aspirin irreversibly inhibits platelet aggregation for cardiovascular protection; salicylic acid does not have this same effect. Willow bark is for pain and inflammation, not cardiac prevention.

Why does willow bark take longer to work than aspirin?

Salicin must first be absorbed, then converted to saligenin in the gut, then oxidized to salicylic acid in the liver. This multi-step metabolism takes 1-2 hours for a single dose and 1-2 weeks of daily use for full anti-inflammatory benefit, compared to aspirin's rapid direct action.
