Ginkgo biloba extract has long been used in traditional medicine, but in recent years, it has gained global recognition as one of the most researched herbal supplements. Derived from the leaves of the ancient Ginkgo biloba tree, this extract is now widely consumed in tablets, teas, and capsules to support cognitive function, enhance memory, and promote overall wellness.
But how much of what you’ve heard is actually backed by science? In this article, we dive deep into the scientifically supported benefits of ginkgo biloba extract, how it works in the body, and what clinical studies say about its effectiveness.
What Is Ginkgo Biloba Extract?
Ginkgo biloba is a tree species native to China, often referred to as a “living fossil” because it has survived for over 200 million years. The extract is made from the dried green leaves of the tree and contains several active compounds, including:
- Flavonoids – known for their antioxidant properties
- Terpenoids – such as ginkgolides and bilobalide, which improve circulation and protect nerve cells
The standardised form of ginkgo biloba extract, often labeled as EGb 761, contains 24% flavone glycosides and 6% terpene lactones, making it the most studied version in clinical trials.
1. Ginkgo Biloba Extract for Cognitive Function and Memory
✅ What the Science Says:
One of the most popular reasons people take ginkgo biloba extract is to support brain health. Numerous studies have explored its effects on memory, attention span, and cognitive processing.
A 2012 meta-analysis published in the journal Psychopharmacology reviewed over 30 clinical trials and found that ginkgo biloba extract significantly improves memory and executive function, especially in older adults with mild cognitive impairment.
A 2016 review published in Journal of Evidence-Based Complementary & Alternative Medicine concluded that ginkgo biloba extract had moderate effects on cognitive performance in patients with dementia and Alzheimer’s disease, particularly when used consistently over several weeks.
Key takeaway: Ginkgo biloba extract can support memory and brain function, especially in ageing adults or those showing early signs of cognitive decline.
2. Enhances Blood Circulation and Heart Health
✅ What the Science Says:
The terpenoids in ginkgo biloba extract help dilate blood vessels and reduce blood viscosity, allowing better circulation to the brain, heart, and extremities.
A 2008 study published in Cell and Molecular Biology showed that ginkgo biloba supplementation improved peripheral blood circulation and reduced symptoms of intermittent claudication (pain caused by poor circulation, typically in the legs).
Another clinical trial in Clinical Interventions in Aging (2013) demonstrated that patients who took ginkgo biloba extract experienced improvements in blood flow and oxygen supply, particularly in elderly populations.
Key takeaway: Ginkgo biloba extract enhances cardiovascular health by improving blood circulation and supporting healthy blood vessels.
3. Powerful Antioxidant Properties
✅ What the Science Says:
Free radicals are unstable molecules that cause oxidative stress and damage to cells, accelerating the ageing process and increasing disease risk. The flavonoids in ginkgo biloba extract have potent antioxidant properties that neutralise free radicals.
A 2017 study in the International Journal of Molecular Sciences highlighted the protective role of ginkgo biloba in preventing oxidative damage in the brain, liver, and retina.
Furthermore, the antioxidant action of ginkgo extract has been shown to protect nerve cells, which is particularly beneficial in neurodegenerative conditions like Parkinson’s and Alzheimer’s disease.
Key takeaway: Ginkgo biloba extract helps combat oxidative stress, protecting the body from premature ageing and cellular damage.
4. Reduces Symptoms of Anxiety and Stress
✅ What the Science Says:
Anxiety is a growing concern in modern society, particularly in high-pressure environments like Malaysia’s urban workforce. Ginkgo biloba extract may help reduce anxiety symptoms by balancing stress hormones and enhancing brain function.
A randomised controlled trial published in Journal of Psychiatric Research (2007) found that patients with generalised anxiety disorder experienced greater improvement in symptoms when taking ginkgo biloba extract compared to a placebo group.
Researchers believe the effect is linked to the extract’s ability to modulate cortisol levels, reduce inflammation, and improve blood flow to the brain.
Key takeaway: Ginkgo biloba extract may offer natural relief for mild anxiety and stress, particularly when used alongside lifestyle changes.
5. May Help with Depression Symptoms
✅ What the Science Says:
While not a substitute for antidepressants, some studies have shown that ginkgo biloba extract may offer supportive benefits for people with depression—especially older adults.
According to a study published in Human Psychopharmacology: Clinical and Experimental (2000), elderly patients with depression showed marked improvement in symptoms when ginkgo extract was added to their standard treatment regimen.
The mechanism is believed to involve increased serotonin and dopamine activity, along with improved neurovascular function.
Key takeaway: Ginkgo biloba extract may play a supportive role in improving mood and emotional balance, especially in older adults.
6. Supports Eye Health and Vision
✅ What the Science Says:
As we age, eye health often deteriorates due to oxidative stress and poor circulation. The antioxidant and vasodilating effects of ginkgo biloba extract make it a promising supplement for eye health.
In a study published in Ophthalmology (1999), ginkgo biloba extract improved vision in patients with normal-tension glaucoma, likely due to enhanced retinal blood flow.
Additional research in the Journal of Ocular Pharmacology and Therapeutics (2003) showed protective effects against age-related macular degeneration, one of the leading causes of blindness in elderly populations.
Key takeaway: Ginkgo biloba extract supports eye health by improving circulation and protecting against age-related vision loss.
7. Reduces PMS Symptoms
✅ What the Science Says:
Ginkgo biloba extract may offer relief for women suffering from premenstrual syndrome (PMS), including mood swings, bloating, and breast tenderness.
A double-blind clinical study published in Journal of Alternative and Complementary Medicine (2009) found that women who took 40 mg of ginkgo biloba extract three times daily experienced significantly less severe PMS symptoms compared to those taking a placebo.
The relief may come from ginkgo’s anti-inflammatory and mood-regulating effects.
Key takeaway: Ginkgo biloba extract could be a natural option to ease PMS discomfort and hormonal mood swings.
8. Potentially Improves Sexual Function
✅ What the Science Says:
Some preliminary studies suggest that ginkgo biloba extract might help with sexual dysfunction, especially when caused by antidepressant medications like SSRIs.
A study in the Journal of Sex & Marital Therapy (1998) reported that 84% of patients experienced improvement in sexual function, including libido and arousal, when taking ginkgo biloba extract.
This effect is believed to stem from enhanced blood flow and improved nitric oxide availability in the blood vessels.
Key takeaway: Ginkgo biloba extract may support sexual wellness, particularly in cases related to medication side effects.
Are There Side Effects to Ginkgo Biloba Extract?
While ginkgo biloba extract is generally safe when used in standard doses, it can cause side effects in some people, especially when taken in high amounts or combined with certain medications. Possible side effects include:
- Headaches
- Dizziness
- Nausea
- Allergic skin reactions
- Bleeding (especially if combined with blood thinners)
Important: People on anticoagulants, pregnant women, or those scheduled for surgery should consult a healthcare provider before using ginkgo biloba extract.
