Ovarian cancer is the fifth most common form of cancer in women, according to the U.K. National Health Service's website, NHS Choices, and is most likely to affect women over 45. Although there are several different types of ovarian cancer, epithelial ovarian cancer is the most common type and affects the cells that cover the surface of the ovaries. It is usually treated with chemotherapy and surgery. The herb ginkgo biloba might also play a role in the prevention or treatment of cancer, although evidence to prove it is an effective ovarian cancer treatment is lacking. Don't use it in place of medical treatments and talk to your doctor before adding it your treatment plan.
Properties and Potential Benefits
Ginkgo biloba is one of the world's longest-surviving trees. Its leaves are used in traditional medicine for a variety of conditions including asthma, hearing loss, stress, dementia and circulatory disorders. The Memorial Sloan-Kettering Cancer Center states that it might help to reduce the risk of ovarian cancer but adds that evidence to prove this is limited. Ginkgo contains a host of bioactive compounds including flavonols and terpenoids, though which of these helps to prevent cancer is unclear.
Administration
Ginkgo may be taken as a tea or liquid tincture, or in capsules or tablets. Guidance regarding the dose required to help prevent ovarian cancer is lacking, but your doctor or herbalist might be able to suggest an appropriate dose. MedlinePlus suggests starting at a low dose and slowly increasing to the required dose to help prevent side effects.
Evidence
Clinical trials evaluating the effects of ginkgo biloba on ovarian cancer are lacking, therefore it is difficult to know for certain whether taking a ginkgo supplement might help ovarian cancer patients. However, an analysis of data from studies evaluating the effect of herbs on ovarian cancer, published in the June 2007 issue of "Cancer Letters," concludes that ginkgo biloba compounds might inhibit ovarian cancer cell growth.
Safety Considerations
MedlinePlus states that ginkgo is likely safe but adds that it might cause mild side effects such as stomach upset and constipation. It might also have anticoagulant effects and increase the risk of bruising and bleeding. Don't consume ginkgo seeds as they contain a toxic chemical that might cause seizures and even death. Keep in mind that ginkgo biloba might interact with other medicines you may be taking, including anticonvulsants and antidepressants.
