What is Ginkgo biloba used for?

Ginkgo biloba is used mainly for cognitive and circulatory health. Standardized extract (often EGb 761) has evidence for modest symptom support in mild-to-moderate dementia and may help intermittent claudication.

Does Ginkgo biloba improve memory in healthy people?

Evidence for improving cognition or memory in otherwise healthy adults is inconsistent. Benefits are more established for symptom support in certain clinical conditions than for general cognitive enhancement.

What is a typical Ginkgo biloba dose?

Common studied doses of standardized extract are 120–240 mg per day, often split into 1–2 doses. Product standardization and consistency matter because extracts can vary.

What are the main safety concerns with Ginkgo biloba?

Ginkgo can increase bleeding risk, especially when combined with anticoagulants, antiplatelet drugs, or NSAIDs. It can also cause side effects such as headache, dizziness, or gastrointestinal upset in some people.

Who should avoid Ginkgo biloba or use it only with medical advice?

People with bleeding disorders, those taking blood-thinning or antiplatelet medications, and anyone preparing for surgery should consult a clinician before use. Pregnant or breastfeeding individuals should also seek medical guidance due to limited safety data.

Description

Ginkgo Biloba is an herbal extract used primarily for cognitive and circulatory health. Its standardized form, EGb 761, is studied for dementia, anxiety, and circulatory issues. Benefits for healthy cognitive function remain unproven.

Moderate

Note on evidence

Evidence is strongest for cognitive function improvement in dementia and peripheral vascular disease. Support for use in healthy individuals or anxiety is weaker.

Supports cognition and daily living in dementia

Moderate

Serious risk: increased bleeding, particularly with anticoagulants or antiplatelet drugs or prior to surgery.
Rare cases of allergic reactions and seizures reported.
Avoid use with blood thinners (e.g., warfarin, aspirin, clopidogrel) due to increased risk of bleeding.
Discontinue at least 2 weeks before elective surgery to reduce bleeding risk.
Not recommended during pregnancy or breastfeeding.
Monitor for signs of bleeding in people with bleeding disorders or peptic ulcer disease.
Use with caution in people with epilepsy due to potential risk of seizures.
