Ginkgo Biloba Precautions

Special precautions & warnings:

Use caution and talk to a health care provider if you:

  • have bleeding disorders
  • have scheduled surgery or dental procedures
  • take anticoagulant medications

Fresh (raw) ginkgo seeds contain large amounts of a chemical called ginkgotoxin, which can cause serious adverse reactions and even seizures and death. Roasted seeds can also be dangerous. Products made from standardized ginkgo leaf extracts contain little ginkgotoxin and appear to be safe when used orally and appropriately.

National Toxicology Program (NTP) studies showed rats and mice developed tumors after being given a specific ginkgo extract for up to 2 years. Further studies are needed to find out what substances in ginkgo caused the tumors and whether taking ginkgo as a dietary supplement affects the risk of cancer in people.
