What are the health benefits of Ginkgo biloba? When should I use this medicinal plant?

Visit Ginkgo biloba is widely used in herbal medicine for a variety of indications, including its beneficial effects on blood circulation, cognitive function and general health.

Here is a list of the most notable benefits of Ginkgo biloba and some of the areas in which this plant can be used:

Improving blood circulation

Ginkgo Biloba blood circulation

The Ginkgo biloba is often used for its beneficial effects on the blood circulationparticularly in the extremities.

This property is largely attributed to the presence of specific compounds such as Ginkgolides and Bilobalideswhich can have vasodilatory effects and antiplatelet effects.

To put it more simply, Ginkgo biloba leaves contain in their composition active ingredients that dilate blood vessels (especially capillaries) that make blood more fluid. As a result, blood circulates better throughout the body, particularly in the extremities, providing cells with the elements they need to function optimally (oxygen and nutrients).

This property can be exploited, for example, in diabetic patients who often develop blood circulation problems (diabetic angiopathy, particularly marked in the extremities of the body, such as the tips of the toes and fingers).

A Chinese study published in 2003 in the Clinical Hemorheology and Microcirculation also revealed that a therapeutic protocol based onGinkgo biloba extract was able to improve brain circulation in mice in which a sub-arachnoid haematoma (cerebral haemorrhage) had been deliberately induced. In this way, it may be possible to help patients who have suffered a cerebral haemorrhage to regain a normal circulation. microcirculation in the brain after surgical treatment, for faster, more effective recovery [1]!

Thanks to its beneficial properties on blood circulationcirculation Ginkgo biloba can be an interesting treatment for situations such as :

  • Intermittent claudication : Intermittent claudication is characterized by pain and cramps in the legs during physical activity due to poor blood circulation. Ginkgo biloba can be used as a supplement to help improve blood flow to the lower limbs and potentially reduce symptoms [2]!
  • Poor peripheral circulation: Conditions such as Raynaud's disease, cold hands and feet, numbness and tingling in the extremities can be linked to poor peripheral blood circulation. Ginkgo biloba could help stimulate blood flow to these areas in people with this problem [3].
  • Cerebrovascular disorders: Since Ginkgo biloba is able to improve blood circulation, it may be considered as a supplement for people concerned with cerebrovascular disorders such as strokes or transient ischemic attacks (TIAs).
  • Age-related disorders : the elderly can benefit from Ginkgo biloba's effects on blood circulation to improve vascular function and potentially reduce the risk of circulation-related problems [4].
  • Glaucoma: Some research suggests that Ginkgo biloba may have a beneficial effect on blood circulation in the eyes, potentially helping to reduce symptoms of glaucoma, a condition linked to high intraocular pressure [5].
  • Circulatory tinnitus: Some small-scale work suggests that Ginkgo biloba may be able to treat tinnitus (hearing whistling, buzzing, popping, etc.) caused by circulatory disorders, but further evaluation is needed to confirm these findings [6].
Ginkgo Biloba blood circulation

It should be pointed out that scientific evidence concerning the use of Ginkgo biloba in these conditions may vary. Therefore, before using Ginkgo biloba for circulation problems, consult your doctor to discuss your symptoms, treatment needs and the possibility of incorporating Ginkgo biloba into your care plan.

Memory and brain function support

Extracts of Ginkgo biloba extracts are also well-known in traditional medicine for support memory and brain function (virtues recognized by the World Health Organization and proven by numerous studies).

Ginkgo Biloba brain function

Here are a few mechanisms through which the Ginkgo biloba may improve memory and brain function:

  • Improved cerebral circulation: Active compounds such as Ginkgolides and Bilobalides found in Ginkgo biloba leaves can help dilate blood vessels, improving blood flow to the brain. This can contribute to better oxygenation of nerve cells and supply of nutrients [1].
  • Antioxidant effect: Antioxidants in Ginkgo biloba help neutralize free radicals, which are unstable molecules linked to aging and cell damage. This can help protect nerve cells from oxidative stress, thus preserving brain function and cognitive performance [7], [8].
  • Supporting brain plasticity: Some research suggests that Ginkgo biloba may influence brain plasticity, i.e. the brain's ability to adapt and form new neuronal connections, which is crucial for learning and memory [9].
  • Reduced inflammation: Ginkgo biloba's compounds may also have anti-inflammatory properties, which could help preserve brain health by reducing chronic inflammation [10].
  • Prevention of cognitive decline: Some studies suggest that regular intake of Ginkgo biloba may be associated with a slowing of age-related cognitive decline and memory loss, although results vary [11].

Although its effects are not always conclusive, and further research is needed, here are some conditions and situations in which Ginkgo biloba may be useful. Ginkgo biloba can be considered to support memory and cognitive functions:

  • Age-related cognitive decline.
  • Prevention of senile dementia and Alzheimer's disease.
  • Mild memory impairment.
  • Improved concentration and mental clarity.
  • Support after stroke.
  • Support for cognitive function in young adults.
  • Attention and concentration disorders in children.

Of course, if you plan to use Ginkgo biloba to support memory and cognitive functions, consult a healthcare professional first for personalized advice.

Antioxidant power

The antioxidant power of Ginkgo biloba is one of the plant's most widely studied and praised properties [7], [8].

It should be noted that antioxidants antioxidants are compounds that help protect the body's cells against damage caused by free radicalsfree radicals unstable molecules produced during the normal body metabolism as well as by external factors such as the pollutionpollution stress and ultraviolet radiation.

Damage caused by free radicals can actively contribute to premature agingand chronic diseases and health problems.

Visit Ginkgo biloba contains various antioxidant compoundsincluding flavonoidsflavonoids terpenoidsterpenoids Ginkgolides and Bilobalidescompounds that have been widely shown to neutralize free radicals and protect cells against oxidative damage.

The antioxidant power of Ginkgo biloba can be very beneficial to health by :

  • Cell protection : the antioxidants present in Ginkgo biloba help protect the body's cells, including nerve cells (neurons), from damage caused by free radicals.
  • Support for heart health: Ginkgo biloba's antioxidant properties can help maintain healthy blood vessels and reduce the risk of cardiovascular disease.
  • Better neuroprotection: Ginkgo biloba's antioxidant properties may also play a role in protecting nerve cells, helping to prevent cognitive decline and neurological disorders.
  • Anti-inflammatory role: Some of Ginkgo biloba's antioxidant effects can help reduce inflammation in the body, which is important for the prevention of many chronic diseases.
