Pregnancy, Breastfeeding & Children
Pregnancy
AvoidWhite willow bark contains salicin, which the body converts toward aspirin-like compounds — contraindicated in pregnancy for the same reasons aspirin is generally avoided (bleeding risk, potential effects late in pregnancy).
Breastfeeding
AvoidSalicin content means it's generally avoided during breastfeeding, mirroring aspirin precautions.
Children
AvoidSalicin-containing herbs are avoided in children and teenagers recovering from viral illness due to a theoretical Reye's syndrome risk, the same concern as with aspirin.

Quality tips
When buying Willow Bark (Iva), look for: certified organic labelling, clearly stated country of origin, third-party lab testing for heavy metals and pesticides, and a batch expiry date. Standardised extracts offer consistent dosing; bulk dried herbs are more economical for regular use. Avoid very cheap, unlabelled products — quality varies enormously.
