Interactions with Devil's Claw

Devil's claw and warfarin may interact, resulting in purpurea (Shaw et al. 1991). The mechanism for this interaction is unclear and there is no data available regarding effects from rechallenge. Patients taking devil's claw with anticoagulants should be monitored closely for clinical signs of over-coagulation or bleeding disorders.
