Synopsis

Source of validity: Scientific
Rating (out of 5): 2

Ginkgo biloba is one of the most widely used herbal supplements for cognitive health, including the support and treatment of Alzheimer's disease. Its use for memory and mental clarity is rooted in traditional Chinese medicine; however, there has also been scientific investigation into its potential benefits for dementia and Alzheimer's disease. Ginkgo biloba contains several active compounds, including flavonoids and terpenoids, which are thought to have antioxidant and anti-inflammatory properties. These properties could theoretically protect nerve cells from damage associated with Alzheimer’s disease.

Clinical studies and systematic reviews have produced mixed results. Some randomized controlled trials have found that standardized ginkgo extracts (such as EGb 761) may have a small, beneficial effect on cognitive function and activities of daily living in people with mild to moderate dementia, including Alzheimer's disease. However, other well-designed studies, such as the large Ginkgo Evaluation of Memory (GEM) study, found no significant benefit for prevention or treatment of dementia compared to placebo. Meta-analyses suggest that if there is a benefit, it is modest at best.

Overall, while there is scientific interest and some supportive evidence, the effects are not consistently strong or clinically significant. Ginkgo is generally considered safe for most people, but it can interact with medications and may increase bleeding risk. Thus, while it is used with some scientific basis, the quality of the supporting evidence is moderate to low, justifying a rating of 2 out of 5.
