Ginkgo biloba Extract—Improve blood circulation and protect the nervous system
2025-11-27
Q: What is Ginkgo biloba Extract?
Ginkgo biloba Extract is a light yellowish-brown powder produced by reflux extraction with dilute ethanol and resin purification of dried leaves from the Ginkgo biloba plant. It possesses effects such as improving blood circulation, antioxidant activity, and neuroprotection. Its active components, flavonoid glycosides and terpenoids, dilate cerebral blood vessels and inhibit platelet aggregation. It is used as an adjunctive treatment for conditions like cerebral hypoperfusion and diabetic retinopathy, and serves as a food additive in industries such as dairy products and fruit juices.
Q: What are the core components of Ginkgo biloba Extract?
The efficacy of Ginkgo biloba Extract stems from the synergistic action of its multiple constituents. The two most crucial categories are:Flavonoid glycosides, which possess potent antioxidant properties, helping combat free radicals and protect cells (especially nerve cells and vascular cells) from oxidative damage; Terpenoids (including ginkgolides and bilobalides), unique to ginkgo, primarily inhibit platelet-activating factor. This means they can reduce excessive platelet aggregation, thereby improving blood circulation, particularly microcirculation.
Q: What are the primary benefits of Ginkgo biloba Extract?
1. Enhances brain function and cognitive health. By increasing cerebral blood flow and oxygen supply, it may improve memory, attention, and mental clarity. Commonly used to support treatment for age-related cognitive decline, Alzheimer's disease, and vascular dementia. Some studies indicate it can stabilize or mildly improve patients' cognitive function and social behavior.
2. Enhances peripheral blood circulation. It may be used to treat conditions caused by poor circulation, such as intermittent claudication (leg pain during walking). Studies indicate it can extend the pain-free walking distance for patients.
3. Relieves tinnitus and vertigo. In some countries, it is approved for treating unexplained tinnitus and vertigo.
4. Antioxidant and anti-inflammatory effects. Flavonoids help reduce oxidative stress and inflammation, potentially benefiting various chronic conditions.
Q: What are the primary application areas of Ginkgo biloba Extract?
1. Pharmaceutical field. This is its core application area, with related formulations used across multiple departments to treat various diseases. In neurology, it addresses acute and chronic cerebral dysfunction (including stroke, attention deficits, memory decline, dementia) and their sequelae, while also aiding cognitive impairment. In cardiology, it alleviates symptoms like coronary heart disease and angina caused by cardiac blood stasis, and treats peripheral circulatory disorders such as arterial occlusive disease. In ophthalmology, it addresses ocular blood flow and neural disorders like diabetic retinopathy, age-related macular degeneration, and chronic glaucoma. Additionally, it can be formulated as an aerosol for asthma management or as a mouthwash for periodontal disease treatment.
2. Health Supplement Sector. Leveraging its natural regulatory properties, it is commonly formulated into oral health supplements. For middle-aged and elderly individuals, products enhance memory and prevent cognitive decline. For those requiring metabolic regulation, supplements assist in balancing blood sugar and lipids with bidirectional effects, minimizing hypoglycemia risks. For endurance athletes or frequent exercisers, supplements containing this extract help reduce post-exercise blood lactate levels and alleviate muscle fatigue. Functional health products also address anxiety relief and respiratory system protection, catering to diverse health needs.
3. Cosmetics Sector. Flavonoids inhibit matrix metalloproteinase activity, reducing collagen degradation, making them a common active ingredient in skincare products. Currently available creams and lotions containing this extract can enhance skin elasticity and reduce wrinkles with long-term use, delivering anti-aging benefits. Furthermore, leveraging novel liposome encapsulation technology, transdermal patches incorporating this ingredient have been developed to improve skin penetration of active compounds, thereby enhancing skincare efficacy.
