Organic Ginkgo Leaf Extract

Also known as: Maidenhair Tree, Ginkgo, Ginkgo Biloba, Ginkgo biloba

Overview

Ginkgo biloba is a prehistoric tree species known for its fan-shaped leaves and is renowned for its medicinal properties. Extracts from the leaves are rich in flavonoids, particularly glycosides, and terpene lactones, which contribute to various health benefits. Commonly used in alternative medicine, Ginkgo biloba is primarily indicated for cognitive enhancement, improvement of circulatory disorders, and management of diseases like Alzheimer's and diabetic kidney disease. Standardized extracts, such as EGb761, provide a consistent formulation that contains 24% flavonoid glycosides and 6% terpene lactones with regulated limits on ginkgolic acid content. Research has shown promising effects in improving cognitive function and kidney health, with substantial evidence derived from random controlled trials and systematic reviews.

Benefits

Ginkgo biloba exhibits several evidence-backed benefits: 1. **Cognitive Function**: Meta-analysis indicates significant cognitive improvement in dementia patients (SMD = -0.90) particularly in Alzheimer's and vascular dementia. 2. **Diabetic Kidney Disease**: Systematic review shows enhanced outcomes in kidney patients when combined with standard medications. 3. **Cardiovascular Health**: Exhibits antioxidant properties, reduces oxidative stress, and regulates blood lipids. 4. **Blood Metabolism in Type 2 Diabetes**: Helps improve metabolic parameters like glycemic control and lipid profiles. Evidence suggests that benefits, particularly in cognitive function, manifest over months of treatment.

How it works

Ginkgo biloba acts through multiple physiological mechanisms, particularly by reducing oxidative stress through its flavonoids and terpene lactones. These compounds inhibit inflammatory factors, enhance blood flow, and regulate blood lipids. They also inhibit platelet activating factors, which can improve circulation and protect against neurodegeneration. This multimodal action interacts notably with the cardiovascular, cerebrovascular, and neurological systems, promoting enhanced blood flow and reducing inflammation, which contribute to its therapeutic effects.

Side effects

Ginkgo biloba is generally considered safe; however, potential side effects exist: - **Common Side Effects (over 5%)**: Gastrointestinal discomfort, headache, and dizziness. - **Uncommon Side Effects (1-5%)**: Allergic reactions and bleeding disorders, which may occur due to its antiplatelet properties. - **Rare Side Effects (less than 1%)**: Severe allergic reactions and reports of seizures. Patients should be cautious if they have bleeding disorders or are taking anticoagulants or antiplatelet drugs, as these may have serious interactions. Pregnant, breastfeeding women, and children are advised to limit use due to a lack of safety data.

Dosage

The recommended dosage of Ginkgo biloba varies based on the condition being treated. For cognitive support, a minimum effective dose of 120 mg per day is commonly cited, with optimal ranges between 120 mg to 240 mg. The maximum safe dose occurs at 240 mg daily; however, higher amounts should only be taken with medical supervision. Consistent daily administration is advised, and while there are no specific timing recommendations, taking extracts like EGb761 with food may enhance absorption due to improved bioavailability.

FAQs

Is Ginkgo biloba safe?

Generally, Ginkgo biloba is safe for most users, but it should be used cautiously by individuals with bleeding disorders or those on anticoagulant medications.

When should Ginkgo biloba be taken?

It's recommended to take Ginkgo biloba consistently each day, with or without food, to maximize its efficacy.

How long does it take for Ginkgo biloba to work?

Cognitive and metabolic improvements may begin to manifest after several weeks to months of consistent use.

Can Ginkgo biloba cure dementia?

Ginkgo biloba is not a cure for dementia; rather, it may serve as a beneficial adjunctive therapy in managing symptoms.
