1, remove vascular garbage and prevent cerebral thrombosis and stroke. Risk factors for stroke include hypertension, arteriosclerosis, heart disease and diabetes. Ginkgo biloba leaves can inhibit the production of a substance called platelet activating factor (RSF) in human body. RSF affects the blood flow in arteries, reduces the blood flow to the brain, and leads to hypoxia of brain cells. Many studies have shown that Ginkgo biloba leaves can greatly increase the blood flow of the brain and accelerate the recovery after stroke.

2. Improve blood supply to the brain. Carotid artery is the main channel for blood transfusion to the brain. Injecting Ginkgo biloba extract into animals can increase carotid blood flow and get more blood in the brain.

3. Anti-myocardial ischemia. Scientists ligate the coronary artery of dogs to imitate human myocardial infarction. When Ginkgo biloba extract is injected into animals with myocardial injury, the ECG abnormality will be improved.

4. Adjust blood lipid and reduce blood viscosity. Ginkgo biloba leaves can help dilute blood, inhibit thrombosis and improve blood circulation without side effects. Therefore, Dr. Mander in the United States called Ginkgo biloba a "very creative" medicine.
