Ginkgo biloba has many health benefits. It’s often used to treat mental health conditions, Alzheimer’s disease, and fatigue. It’s been used in traditional Chinese medicine for about 1,000 years. It came on the Western culture scene a few centuries ago but has enjoyed a surge of popularity over the last few decades.
Ginkgo is used as a herbal remedy to treat many conditions. It may be best known as a treatment for dementia, Alzheimer’s disease, and fatigue. Other conditions it’s used to treat are:
- anxiety and depression
- insufficient blood flow to the brain
- blood pressure problems
- altitude sickness
- erectile dysfunction
- premenstrual syndrome
- attention deficit hyperactivity disorder (ADHD)
- macular degeneration
Ginkgo’s health benefits are thought to come from its high antioxidant and anti-inflammatory properties. It may also increase blood flow and play a role in how neurotransmitters in the brain operate.
Some studies support the effectiveness of ginkgo. Other research is mixed or inconclusive. In 2008, results of the Ginkgo Evaluation of Memory (GEM) study trusted Source were released. The study sought to find out if ginkgo would reduce the occurrence of all types of dementia, including Alzheimer’s disease. It also looked at ginkgo’s impact on:
- overall cognitive decline
- blood pressure
- incidence of cardiovascular disease and stroke
- overall mortality
- functional disability
The GEM study, the largest of its kind to date, followed 3,069 people age 75 or older for 6 to 7 years. Researchers found no effect for preventing dementia and Alzheimer’s disease in study participants who either took ginkgo or a placebo. And a 2012 meta-analysisTrusted Source found ginkgo had no positive effects on cognitive function in healthy people.
The GEM study also found ginkgo didn’t reduce high blood pressureTrusted Source. There was also no evidence ginkgo decreases the risk of heart attack or stroke. It may, however, reduce the risk of peripheral artery disease trusted Source caused by poor blood circulation.
According to a 2013 systematic review, ginkgo can be considered an adjuvant therapy for schizophrenia. Researchers found ginkgo seemed “to exert a beneficial effect on positive psychotic symptoms” in people with chronic schizophrenia who take antipsychotic medication.
Researchers in that study also found positive study results for ADHD, autism, and generalized anxiety disorder, but indicated more research is needed.
According to an older review of evidence study, ginkgo may improve erectile dysfunction caused by antidepressant medications. Researchers believe ginkgo increases the availability of nitric oxide gas which plays a role in increasing blood flow to the penis.
Ginkgo may help relieve premenstrual syndrome (PMS) symptoms, according to a 2009 study. During the study, participants taking either ginkgo or placebo experienced a reduction in symptoms. Those taking ginkgo had significantly more relief.
Ginkgo is generally safe for healthy people to use in moderation for up to six months. Severe side effects are rare.

Potential athletic benefits are:
- A potent antioxidant.
- Supports muscle building.
- Improves oxygenation to the muscles.
