Valerian

Probiotics

Ginkgo biloba

Coenzyme Q10

Answer and Explanation

The Correct Answer is C

A. Valerian is an herbal supplement commonly used for its sedative effects. It does not have a significant interaction with warfarin and is not contraindicated for concurrent use.
B. Probiotics are generally safe to use with warfarin and do not have a significant impact on its anticoagulant effects. They are not contraindicated for concurrent use.
C. Ginkgo biloba is known to increase the risk of bleeding when taken with warfarin. It has antiplatelet effects that can enhance the anticoagulant effects of warfarin, leading to an increased risk of bleeding complications. Therefore, it is contraindicated for concurrent use with warfarin.
D. Coenzyme Q10 is structurally similar to vitamin K and can potentially reduce the effectiveness of warfarin. However, it is not as strongly contraindicated as ginkgo biloba, which has a more pronounced effect on bleeding risk.
