Ginkgo Biloba: Enhancing Circulation, Memory, and Concentration

Ginkgo Biloba: Enhancing Circulation, Memory, and Concentration

Published on | Written by | modified

Ginkgo Biloba, derived from one of the oldest living tree species, has been used in traditional Chinese medicine for millennia and is now one of the most widely used herbal supplements globally. Its popularity stems from its potential to improve blood circulation and cognitive functions, such as memory and concentration. This article delves into the scientific evidence supporting these benefits.

1. Ginkgo Biloba and Blood Circulation

Ginkgo Biloba is well-regarded for its ability to enhance blood circulation.

  • Vascular Health: A study in the "Journal of Cardiovascular Pharmacology" reports that Ginkgo Biloba extract can improve blood flow by dilating blood vessels and reducing the stickiness of blood platelets【1】.
  • Peripheral Artery Disease: This improved circulation is particularly beneficial in conditions like peripheral artery disease, as indicated in research published in "Clinical Research in Cardiology"【2】.

2. Cognitive Enhancement and Neuroprotective Effects

One of the most compelling uses of Ginkgo Biloba is its potential to enhance cognitive function.

  • Memory and Concentration: Research in "Phytomedicine" suggests that Ginkgo extract can improve memory, attention, and processing speed in healthy adults【3】.
  • Neuroprotection: Ginkgo's antioxidant properties contribute to its neuroprotective effects, helping to prevent cognitive decline and supporting brain health, as noted in the "Journal of Alzheimer's Disease"【4】.

3. Ginkgo Biloba in Treating Dementia and Alzheimer’s Disease

Ginkgo Biloba has been studied for its potential benefits in slowing the progression of dementia and Alzheimer’s disease.

  • Alzheimer’s Disease: A review in "The Cochrane Database of Systematic Reviews" concluded that Ginkgo Biloba might stabilize or slightly improve cognitive function and the performance of daily activities in patients with cognitive impairment and Alzheimer’s disease【5】.

4. Antioxidant Properties

The leaves of the Ginkgo Biloba tree are rich in antioxidants, such as flavonoids and terpenoids.

  • Fighting Oxidative Stress: These compounds help combat oxidative stress, a factor in chronic diseases and aging, as discussed in "Biochemical Pharmacology"【6】.

5. Safety and Dosage

While Ginkgo Biloba is generally safe, it's important to understand the correct dosage and potential interactions.

  • Recommended Dosage: Dosages in studies vary, but most effective doses range from 120 to 240 mg per day, divided into several doses.
  • Side Effects and Interactions: Ginkgo can cause mild side effects like headache and stomach upset. It may also interact with blood thinners and other medications.

6. Forms of Ginkgo Biloba

Ginkgo Biloba is available in various forms, including standardized extracts, capsules, and tablets, allowing for flexible ways to incorporate it into your health regimen.


Ginkgo Biloba offers promising benefits for blood circulation and cognitive health, making it a valuable supplement for those looking to enhance mental performance and overall vascular health. However, as with any supplement, it is important to consult with a healthcare provider before starting Ginkgo, especially for individuals on medication or with existing health conditions.
