Ginkgo Biloba, also known as the maidenhair tree, is one of the oldest living tree species on Earth and has a rich history of medicinal use. It's native to China and has been cultivated for thousands of years for its therapeutic properties. Today, Ginkgo Biloba is widely used as a dietary supplement and herbal remedy for various health conditions, particularly those related to cognitive function and circulation.
History and Traditional Use
The use of Gingko Biloba can be traced back to ancient Chinese medicine, where its leaves were brewed into teas or extracts for their medicinal properties. Traditional Chinese medicine practitioners used Gingko Biloba to treat asthma, bronchitis, and various neurological disorders. Its use spread to Europe in the 18th century, where it gained popularity as a remedy for memory enhancement and circulation problems.
Active Ingredients and Mechanisms of Action
- Active Ingredients
- Flavonoids: Gingko Biloba contains various flavonoids, including quercetin, kaempferol, and isorhamnetin. These compounds are potent antioxidants that help neutralize free radicals and reduce oxidative stress in the body. Flavonoids also have anti-inflammatory properties, which contribute to Gingko Biloba's therapeutic effects.
- Terpenoids (Ginkgolides and Bilobalide): Ginkgolides and bilobalide are unique terpenoid compounds found in Gingko Biloba. Ginkgolides, specifically ginkgolides A, B, and C, have been shown to inhibit platelet-activating factor (PAF), a molecule involved in inflammation, blood clotting, and allergic reactions. By blocking PAF, ginkgolides help improve blood flow, reduce platelet aggregation, and protect against cardiovascular diseases. Bilobalide, on the other hand, has neuroprotective properties and may enhance cognitive function by promoting neuronal survival and inhibiting apoptosis (cell death) in the brain.
- Mechanisms of Actions
- Improvement of Blood Flow: One of the primary mechanisms of action of Gingko Biloba is its ability to improve blood circulation throughout the body, including to the brain. Flavonoids and terpenoids in Gingko Biloba help dilate blood vessels (vasodilation), which increases blood flow and oxygen delivery to tissues. This enhanced circulation is beneficial for cognitive function, cardiovascular health, and conditions such as peripheral artery disease and erectile dysfunction.
- Neuroprotection: Gingko Biloba exerts neuroprotective effects through multiple mechanisms. Flavonoids and terpenoids in Gingko Biloba act as antioxidants, scavenging free radicals and reducing oxidative stress in the brain. By protecting neurons from oxidative damage, Gingko Biloba may help prevent neurodegenerative diseases such as Alzheimer's and Parkinson's. Additionally, ginkgolides and bilobalide have been shown to modulate neurotransmitter activity, particularly acetylcholine, serotonin, and dopamine, which are crucial for memory, mood, and cognitive function.
- Anti-inflammatory Activity: Chronic inflammation plays a significant role in the pathogenesis of various diseases, including cardiovascular disorders and neurodegenerative conditions. Gingko Biloba contains bioactive compounds with anti-inflammatory properties that help suppress inflammatory pathways and cytokine production. By reducing inflammation, Gingko Biloba may mitigate tissue damage, improve vascular health, and support overall well-being.
- Antioxidant Defense: The antioxidant properties of Gingko Biloba contribute to its therapeutic effects on multiple organ systems. Flavonoids and terpenoids in Gingko Biloba scavenge reactive oxygen species (ROS) and inhibit lipid peroxidation, thereby protecting cell membranes and DNA from oxidative damage. This antioxidant defence system helps maintain cellular integrity, reduce the risk of chronic diseases, and slow the aging process.
- Platelet Function Inhibition: Ginkgolides found in Gingko Biloba inhibit platelet-activating factor (PAF), a pro-inflammatory and pro-thrombotic mediator involved in platelet aggregation and blood clot formation. By blocking PAF receptors on platelets and endothelial cells, ginkgolides reduce platelet aggregation, prevent thrombosis, and improve blood fluidity. This antiplatelet effect is beneficial for cardiovascular health and may help prevent stroke, myocardial infarction, and other thrombotic events.

Health Benefits of Gingko Biloba
- Eye Health: Gingko Biloba may offer benefits for eye health, particularly in conditions such as age-related macular degeneration (AMD) and glaucoma. The antioxidant properties of Gingko Biloba help protect retinal cells from oxidative stress, potentially slowing the progression of AMD. Furthermore, by improving blood flow to the eyes, Gingko Biloba may help reduce intraocular pressure, which is a risk factor for glaucoma.
- Tinnitus Relief: Tinnitus, or ringing in the ears, can be distressing and affect the quality of life. Some research suggests that Gingko Biloba may help alleviate tinnitus symptoms by improving blood circulation to the auditory system and reducing nerve damage. While results are mixed, some studies have shown that Gingko Biloba supplementation can lead to a reduction in tinnitus severity and improve overall subjective well-being in individuals with this condition.
- Neurological Disorders: Beyond cognitive enhancement, Gingko Biloba shows promise in the management of various neurological disorders. Research suggests that Gingko Biloba may have neuroprotective effects against conditions such as Parkinson's disease and Alzheimer's disease. It may help mitigate neurodegeneration by reducing oxidative stress, inflammation, and the accumulation of toxic proteins in the brain, which are hallmark features of these diseases.
- Exercise Performance: Some studies suggest that Gingko Biloba supplementation may enhance exercise performance and recovery. By improving blood circulation and oxygen delivery to muscles, Gingko Biloba may increase endurance, reduce fatigue, and accelerate recovery following intense physical activity. Additionally, its antioxidant properties may help protect muscles from oxidative damage induced by exercise.
- Skin Health: The antioxidant and anti-inflammatory properties of Gingko Biloba make it beneficial for skin health. Topical formulations containing Gingko Biloba extract have been shown to protect the skin from UV-induced damage, reduce inflammation, and promote wound healing. Gingko Biloba may also help improve skin hydration, elasticity, and overall appearance, making it a valuable ingredient in skincare products.
- Menopausal Symptoms: Gingko Biloba may offer relief from certain menopausal symptoms, such as hot flashes and mood swings. Some studies suggest that Gingko Biloba supplementation can help regulate hormone levels, particularly estrogen, and alleviate vasomotor symptoms associated with menopause. However, more research is needed to fully understand the efficacy of Gingko Biloba in managing menopausal symptoms.
Potential Side Effects and Precautions
While Gingko Biloba is generally considered safe for most people when taken in recommended doses, it may cause side effects such as headaches, dizziness, gastrointestinal upset, and allergic reactions in some individuals. It may also interact with certain medications, including blood thinners, antidepressants, and anticonvulsants, so it's essential to consult with a healthcare professional before starting Gingko Biloba supplementation, especially if you have underlying health conditions or are taking medications.
Dosage Recommendations
The appropriate dosage of Gingko Biloba depends on various factors, including age, health status, and the specific health condition being treated. Generally, typical doses range from 120 mg to 240 mg per day, divided into two or three doses. It's crucial to start with a low dose and gradually increase it to assess tolerance and minimize the risk of side effects.
Conclusion
Gingko Biloba is a fascinating herbal remedy with a long history of traditional use and emerging scientific evidence supporting its health benefits. From cognitive enhancement and improved circulation to antioxidant protection and potential mood benefits, Gingko Biloba offers a range of therapeutic effects. However, it's essential to use it cautiously, adhere to recommended dosages, and consult with a healthcare professional to ensure its safety and efficacy, particularly when used in conjunction with other medications or supplements.
