Interactions with Herbs
Sarsaparilla (Smilax spp.)
Sarsaparilla may increase the absorption of digitalis and bismuth, increasing the chance of
toxicity.1
Salicylate-containing herbs
Bismuth subsalicylate contains salicylates. Various herbs including meadowsweet (Filipendula ulmaria),
poplar (Populus tremuloides),
willow (Salix alba), and wintergreen (Gaultheria procumbens)
contain salicylates as well. Though similar to
aspirin, plant salicylates have been shown to have different actions in test tube
studies.2 Furthermore, salicylates are poorly absorbed and likely do not build up
to levels sufficient to cause negative interactions that aspirin might.3 No reports
have been published of negative interactions between salicylate-containing plants and aspirin
or aspirin-containing drugs.4 Therefore concerns about combining
salicylate-containing herbs remain theoretical, and the risk of causing problems appears to be
low.
