Interactions with Herbs
Willow (Salix alba)
Willow bark contains salicin, a substance similar to aspirin. Aspirin should not be given to children receiving live influenza virus due to the possible link to Reye's syndrome. The same adverse interaction result could theoretically happen if children were to take a willow-containing product following FluMist®.
