Ginkgo biloba is one of the world’s oldest trees: its ancestors are estimated to have populated Earth more than 200 million years ago. This long-lived species, native to China, attracts attention not only for its impressive evolutionary history but also for the benefits attributed to it in traditional and modern medicine. In this article, we will explore in depth what science says about ginkgo biloba, its properties, uses, precautions, and the latest research supporting (or questioning) its effectiveness.
Origins and history of ginkgo biloba
Ginkgo biloba, also known as the “tree of forty crowns” because of its golden autumn leaves, is considered a living fossil. Its origins date back more than 200 million years, when it coexisted with dinosaurs.
- Evolutionary resilience: Throughout history, this tree has survived extreme conditions, including ice ages and atomic bombings (such as Hiroshima).
- Reverence in Asia: In Chinese and Japanese cultures, ginkgo biloba holds deep symbolism of longevity and strength. It has also been used in traditional medicine for centuries to treat various ailments.
Active ingredients and composition
Ginkgo biloba leaves are the most studied part and the most widely used therapeutically. They contain bioactive compounds classified mainly into two major groups:
- Flavonoids: Notably quercetin and kaempferol, with antioxidant properties that help combat cellular damage caused by free radicals.
- Terpenoids (ginkgolides and bilobalides): These compounds are associated with possible vasodilatory and neuroprotective effects.
According to several studies, the synergy between flavonoids and terpenoids in ginkgo biloba extract could improve cerebral circulation and cognitive health.

Potential benefits of ginkgo biloba: what does science say?
- Improved cognitive function
Various studies have suggested that ginkgo biloba could help improve memory and concentration, especially in older people with mild cognitive impairment. However, a meta-analysis published in JAMA (Journal of the American Medical Association) reported mixed findings on ginkgo’s effectiveness in preventing cognitive decline. Even so, many people report a subjective improvement in mental clarity. - Increased blood flow
Ginkgo biloba’s components have been observed to promote vasodilation and reduce platelet aggregation, thereby supporting better circulation. This property has led to its potential use in peripheral circulatory disorders, such as intermittent claudication. - Antioxidant power
Because of its high flavonoid concentration, ginkgo biloba could protect cells against oxidative damage. Oxidative stress is associated with aging and chronic diseases such as arteriosclerosis. - Possible impact on mood
Although more research is required, some preliminary studies indicate that ginkgo could improve mild anxiety and depression symptoms through its action on cerebral circulation and neurotransmitter modulation.
Traditional use and modern applications
In traditional Chinese medicine, ginkgo biloba has been used to treat respiratory problems, reduce asthma, and relieve headaches. Today, the pharmaceutical and supplement industries promote standardized ginkgo extract to:
- Improve memory and concentration
- Reduce symptoms of mental fatigue
- Support microcirculation in the extremities
- Relieve tinnitus (ringing in the ears)
However, results and effectiveness may vary between individuals, and scientific evidence remains inconclusive in many of these areas.
No products found.
Dosage and precautions
The ginkgo biloba dose recommended in most studies ranges from 120 mg to 240 mg daily of standardized extract (usually containing 24% flavonoids and 6% terpenoids). Dividing the dose into two daily servings is generally suggested, preferably with meals to facilitate absorption.
Precautions
- Drug interactions: Ginkgo biloba may have an anticoagulant effect, so extra caution is needed when taking medicines such as warfarin or aspirin.
- Side effects: Although usually well tolerated, headaches, dizziness, nausea, and gastrointestinal discomfort have been reported.
- Pregnancy and breastfeeding: Given the lack of conclusive studies, use during pregnancy or breastfeeding is not recommended without medical supervision.
- Allergies: Some people may be sensitive to ginkgo’s components.
Side effects and contraindications
Although ginkgo biloba is considered safe at moderate doses, certain contraindications should be considered:
- People with blood-clotting problems should consult a healthcare professional before taking it.
- Avoid concurrent use with medicines or supplements having similar effects (anticoagulants, nonsteroidal anti-inflammatory drugs, etc.).
- Stopping ginkgo at least two weeks before surgery is recommended to minimize bleeding risks.
No products found.
New research directions
The scientific community continues to investigate ginkgo biloba’s therapeutic potential in various areas, such as dementia prevention, vascular health improvement, and anxiety disorder treatment. Notable trends include:
- Gut microbiota: Current studies explore how ginkgo’s components might interact with intestinal flora, a key factor in overall health.
- Long-term brain health: Clinical trials focus on determining whether prolonged ginkgo biloba intake could meaningfully slow age-related cognitive decline.
Conclusions
Ginkgo biloba has gained popularity as a natural supplement for memory improvement and circulatory health. Although evidence supports some of its effects, maintaining a critical perspective is crucial: it is not a miracle remedy but a potential ally that could complement a healthy lifestyle and appropriate medical treatment.
If you are considering trying ginkgo biloba, consulting a healthcare professional to determine dosage and review potential interactions with other medicines is advisable. Always listen to your body’s needs and maintain realistic expectations about the results you hope to achieve.
