Ginkgo - What is it & How to use

What is it?

  • Ginkgo, one of the oldest living tree species in the world, has a long history in traditional Chinese medicine. Members of the royal court were given ginkgo nuts for senility. Other historical uses for ginkgo were for asthma, bronchitis, and kidney and bladder disorders.
  • Today, the extract from ginkgo leaves is used as a dietary supplement for many conditions, including dementia, eye problems, intermittent claudication (leg pain caused by narrowing arteries), tinnitus, and other health problems.
  • Ginkgo is made into tablets, capsules, extracts, tea, and cosmetics.
  • There’s no conclusive evidence that ginkgo is helpful for any health condition.
  • Ginkgo doesn’t help prevent or slow dementia or cognitive decline, according to studies, including the long-term Ginkgo Evaluation Memory Study, which enrolled more than 3,000 older adults and was funded in part by the National Center for Complementary and Integrative Health (NCCIH).
  • There’s no strong evidence that ginkgo helps with memory enhancement in healthy people, blood pressure, intermittent claudication, tinnitus, age-related macular degeneration, the risk of having a heart attack or stroke, or with other conditions.
  • Ongoing NCCIH-funded research is looking at whether a compound in ginkgo may help with diabetes.

Safety Concerns

  • For many healthy adults, ginkgo appears to be safe when taken by mouth in moderate amounts.
  • Side effects of ginkgo may include headache, stomach upset, and allergic skin reactions. If you’re older, have a known bleeding risk, or are pregnant you should be cautious about ginkgo possibly increasing your risk of bleeding.
  • In a 2013 research study, rodents given ginkgo had an increased risk of developing liver and thyroid cancer at the end of the 2-year tests.
  • Ginkgo may interact with some conventional medications, including anticoagulants (blood thinners), research reviews show.
  • Eating fresh (raw) or roasted ginkgo seeds can be poisonous and have serious side effects.
