Antagonists of Vitamin K-Popular…oumarin Derivatives.

This was a review of coumarin compounds (natural and synthetic) and how they work in the body—specifically their anticoagulant (blood-thinning) properties. The research focused on prescription drugs like warfarin that use coumarins to prevent clotting, but also explored other potential uses like antioxidant and anti-inflammatory effects. No new skincare findings or efficacy data were reported.
