Which herb is listed as interacting with anticoagulant or antiplatelet medications?

• A. Bai Zhu
• B. Fu Ling
• C. Dang Gui
• D. Dan Shen

Answer: (C)

Moving blood to circulate more strongly can increase bleeding risk when combined with anticoagulant or antiplatelet therapies. Dang Gui is a classic blood-activating herb whose constituents can affect platelet function and, in practice, amplify the effects of blood thinners. That makes it the herb most likely to interact with anticoagulant or antiplatelet medications. Other options in the list don’t carry the same coagulation-altering risk—Bai Zhu and Fu Ling focus on tonifying or damp-dispelling actions without influencing coagulation, and while Dan Shen can also affect bleeding, Dang Gui is the standard example emphasized for this interaction.
