Touted as the "brain herb", Ginkgo Biloba extract (GBE) has received attention for its antioxidant and anti-inflammatory properties, particularly to support cardiovascular and neurological and brain health. Over the past 10-15 years, numerous studies have tested Ginkgo for various actions in treating dementia and Alzheimer's disease, as well as preventing cognitive decline in healthy people.
Ginkgo contains a number of biologically active compounds that work in different ways to support brain health. How these compounds act is not fully known - and is still being researched in animal and human studies - but there are some excellent theories. Ginkgo may work by increasing blood flow in the brain, helping to remove free radicals that can damage cells, and reducing inflammation. It may even protect nerve cells already damaged by Alzheimer's disease or vascular dementia.
Hundreds of published studies have evaluated the effectiveness of Ginkgo in people with dementia and other types of cognitive decline. Several studies show that GBE has a positive effect on memory, learning, and thinking in people with Alzheimer disease or vascular dementia.
Gingko extracts are standardized to specific dosages when used in studies and medical treatment. GBE can interact with blood clotting medications. Be sure to consult with your holistic practitioner before taking Ginkgo.
