Angelica sinensis commonly interacts with which treatments?

• A. Vaccines
• B. Antacids
• C. Anticoagulants and antiplatelets
• D. Beta blockers

Answer: (C)

Angelica sinensis can affect blood clotting, which is why it interacts with treatments that affect coagulation. It contains compounds that can inhibit platelet aggregation and have mild anticoagulant effects, so taking it with anticoagulants (like warfarin or heparin) or with antiplatelet drugs (such as aspirin or clopidogrel) can heighten the risk of bleeding. This is a well-recognized interaction and often requires closer monitoring, dose adjustments, or avoiding the herb in combination with these therapies.

There isn’t a well-established, clinically meaningful interaction with vaccines, antacids, or beta blockers, so those do not represent the same level of concern with Angelica sinensis. Always check with a healthcare professional for individual risk and monitoring if combining herbal and pharmaceutical therapies.
