Ginkgo biloba is a herb that supports mental function by promoting cerebral and peripheral circulation.

What is Ginkgo biloba?

Gingko biloba is a tree whose leaves are used in traditional Chinese medicine for many purposes in particular to support cognitive functions by promoting cerebral and peripheral circulation.

The history of Ginkgo biloba use

Ginkgo biloba trees have lived on earth for approximately 300 million years. Ginkgo biloba trees can reach heights of 40 m and individual trees aged more than 1000 years have a circumference of 10 - 20 m.1

Although Ginkgo biloba is one of the oldest trees on earth, the medicinal properties of the leaf of this herb were only discovered about 40 years ago. There has been extensive research of Ginkgo biloba over the past 40 years identifying benefits derived from its vascular effects.2

The specific standardised extracts used by Flordis

A specific standardised extract of Ginkgo biloba known as GK501 is combined with a specific standardised extract of Panax ginseng known as G115 in the product Gincosan® by Flordis.

GK501 is extracted and formulated using a standardised process. This individual and highly technical process helps to ensure a consistent form and amount of Ginkgo biloba leaf is used in every formulation of Gincosan - meaning each final product will contain the same high quality extracts.

Natural products can vary considerably depending on how they are produced. Flordis believes it’s the science behind growing, harvesting and processing that delivers the true health benefits of natural product. That’s why in the making of a Flordis product, careful attention is applied to plant species and growing methods through to cultivation and harvest, using precise processes to help produce consistent crops. This is continued with extracting and manufacturing of specific ingredients following a series of strict controls to help deliver a consistent product from one batch to the next.

It is this specific product that is tested in clinical trials. And it’s the same product that you receive, which is one of the reasons you can feel good about its effectiveness. Flordis products follow processes where all of the steps involved in the growth and manufacture of the natural product are tightly controlled to reduce variability and to help ensure consistency.

How it works

Researchers are still investigating exactly how the combination of Ginkgo biloba and Panax ginseng supports physical and mental endurance and performance. Various research has demonstrated that Ginkgo biloba has antioxidant and neuroprotective activities. It can positively regulate both BDNF (Brain Derived Neurotropic Factor) levels as well as have an impact on synaptic plasticity, which is believed to be the main mechanism supporting memory and learning processes.3-6
