Ginkgo Biloba
Ginkgo biloba is a herbal supplement that people take to treat memory dysfunction and blood disorders. Studies show that this supplement contains compounds that can block thrombin [4], an enzyme responsible for blood clotting. However, more research is needed to know how Ginkgo affects blood clotting in the human body. You can use the extract of Ginkgo biloba as capsules or tablets, but you must first contact your doctor.
