Ginkgo biloba is a natural herbal product advertised as a memory enhancer. It's used to improve mental alertness and give patients clear thinking. Many older adults use it to prevent dementia. Some patients use it for ringing in the ears and for dizziness.
Ginkgo biloba has an i>anticoagulant property. This means it acts like a blood thinner. It keeps platelets in the blood from clumping together to form a blood clot. That's good if you are at risk for blood clots. But it's not good after an operation when bleeding doesn't stop.
It's always best to follow the advice of your doctor and nurse. It's just for a short time until your body returns to normal. Be sure and ask when you can resume taking it again.
