This herb may be contraindicated in individuals with active bleeding (eg, peptic ulcer
, intracranial bleeding). Use with caution in individuals with a history of bleeding, hemostatic disorders, or drug-related hemostatic problems. It should not be used if you are taking anticoagulant medications, including warfarin, aspirin, aspirin-containing products, NSAIDs, or antiplatelet agents (eg, ticlopidine, clopidogrel, dipyridamole). I am not sure of what other potential drug interactions.
