Which herb should be avoided with cholesterol-lowering agents and anticoagulants?

• A. Ginger
• B. Garlic
• C. Ginkgo
• D. Turmeric

Answer: (B)

Garlic is known for strong antiplatelet effects that can potentiate anticoagulants, increasing the risk of bleeding. It can also influence drug metabolism, potentially altering levels of cholesterol-lowering medications and anticoagulants. Because of this dual interaction risk, garlic should be avoided when a patient is taking both a cholesterol-lowering agent and an anticoagulant. While other herbs may have anticoagulant activity, garlic has the most consistently documented dual interaction, making it the most important caution in this context.
