ALL ABOUT GINKGO BILOBA: HISTORY, EFFECTS AND USES
Ginkgo Biloba is one of the oldest tree species in the world, with a history dating back millions of years. The leaves of this tree contain bioactive compounds that have been used in traditional Chinese medicine for centuries. Today, Ginkgo Biloba is often sold as a supplement because of its purported health benefits. In this article, we discuss the history, proven effects and proper use of this special plant.
What is Ginkgo Biloba?
Ginkgo Biloba, also known as the Japanese walnut tree, is native to China and can grow up to 40 metres tall. This tree is considered a living fossil, as it has been around for more than 200 million years. In East Asia, Ginkgo Biloba symbolises strength and longevity, and it is often associated with spiritual and magical properties.
Although the seeds and leaves of the tree have been used in traditional medicine for thousands of years, it is important to note that traditional use does not always provide scientific evidence. Therefore, let's look at the most researched uses of Ginkgo Biloba.
Proven effects of Ginkgo Biloba
Heart and blood circulation
Ginkgo Biloba contains flavonoids and terpenoids, substances that can dilate blood vessels and potentially promote blood flow. Some studies suggest that this may help improve blood flow, which may be useful for conditions such as high blood pressure or peripheral vascular disease. Note that the scientific evidence for this is inconclusive, and further studies are needed to draw definitive conclusions.

Memory and dementia
Ginkgo Biloba is often promoted as a remedy to improve memory and cognitive function. Although some animal studies (e.g. in rats) show improvements in short-term memory, results in humans are mixed. In patients with dementia, Ginkgo can potentially slow mental decline and reduce behavioural problems. Important: This effect is not generally proven and should always be discussed with a doctor.
Source: A review published in JAMA concludes that Ginkgo Biloba supplement may have minor benefits for people with dementia, but the evidence is limited.
Mood and fatigue
Traditional medicine has used Ginkgo Biloba for centuries against depressive symptoms and fatigue. Recent studies suggest that the supplement may affect neurotransmitters such as serotonin and dopamine, which play a role in regulating mood. In addition, it may help improve sleep quality and concentration in people with chronic fatigue. Note: Effectiveness varies widely, and use should always be in consultation with a doctor.

Antioxidants and overall health
The leaves of Ginkgo Biloba are rich in antioxidants, which can neutralise harmful free radicals in the body. This can potentially help protect against oxidative stress, a process associated with diseases such as diabetes and neurological disorders. Note: Antioxidants from food often have a limited effect on their own power, depending on a person's health condition and lifestyle.
Dosage and use of Ginkgo Biloba
The recommended dosage varies depending on the product. Usually an amount of 80-160 mg, divided into two doses per day, is considered safe. Important: Always consult a doctor before using a supplement such as Ginkgo Biloba, especially if you are taking medication or have health problems.
Warning: Ginkgo Biloba may increase the risk of bleeding, especially when combined with blood thinners such as aspirin or warfarin.
What should I pay attention to when using Gingko Biloba?
Ginkgo Biloba is a fascinating supplement with potential for improving blood flow, cognitive function and mood. Although some effects have been supported by research, it is important to be careful with health claims. Always use this supplement under the guidance of a doctor and base your choices on reliable sources of information.
