What is Ginkgo Biloba for?

Ginkgo Biloba is a herb traditionally used as a supplement. Only the extract from the leaf of Ginkgo Biloba are considered to be clinically useful, while the seed extracts are considered poisonous. 

The main components that enable Ginkgo Biloba to have clinical values are terpene lactones and ginkgo flavone glycosides. These two groups of substances possess antioxidant properties and can dilate your blood vessels. Some studies also found that Ginkgo Biloba might help inhibit acetylcholinesterase in the central nervous system, which is an important substance involved in the progression of different neurological disorders. Ginkgo Biloba is commonly taken as a supplement to improve cognitive function and blood vessels problems. However, there is still limited scientific evidence to make definite conclusions about the effectiveness of Ginkgo Biloba.

How to use it?

Ginkgo Biloba is usually taken by mouth as tablets, capsules, extracts and herbal tea. The usual adult dose is 120-240 mg daily in two to three doses. For specific dosages, refer to the product label.

What are the side effects of Ginkgo Biloba?

The side effects of taking Ginkgo Biloba are nausea and vomiting, diarrhoea, headaches and allergic skin reactions.
