Health Benefits of Ginkgo Biloba Leaf Extract
Ginkgo Biloba’s natural health benefits have been recognized by practitioners of traditional medicine. They use health benefits to treat circulatory disorders and enhance memory. The health benefits of ginkgo Biloba are:
- Anxiety. Research shows that taking a specific ginkgo extract (EGb 761, Dr. Willmar Schwabe Pharmaceuticals) for 4 weeks can reduce symptoms of anxiety.
- Mental function. Although some conflicting evidence exists, most research suggests that ginkgo can slightly improve memory, speed of thinking, and attention in healthy adults. Doses of 120-240 mg per day seem to be as effective as or more effective than higher doses up to 600 mg per day. Some research has investigated the effects of ginkgo when used with other supplements. Some evidence suggests that taking ginkgo in combination with Panax ginseng or codonopsis can improve memory better than the individual ingredients alone. However, a specific combination of ginkgo and Panax ginseng (Gincosan, Pharmaton Natural Health Products) does not seem to improve mood or thinking in postmenopausal women. Also, taking a specific product containing ginkgo and brahmi (Blackmores Ginkgo Brahmi) does not seem to improve memory or problem solving in healthy adults.
- Dementia. Some evidence shows that taking ginkgo leaf extract by mouth modestly improves symptoms of Alzheimer’s, vascular, or mixed dementias. However, there are concerns that findings from many of the early ginkgo studies may not be reliable. Although most clinical trials show ginkgo helps for symptoms of Alzheimer’s disease and other dementias, there are some conflicting findings, suggesting it may be hard to determine which people might benefit.
Early research shows that taking a specific ginkgo leaf extract called EGb 761 (Dr. Willmar Schwabe Pharmaceuticals) daily for 22-24 weeks seems to be as effective as the drug donepezil (Aricept) for treating mild to moderate Alzheimer’s disease. But, other research suggests that ginkgo leaf extract might be less effective than the conventional drugs donepezil (Aricept) and tacrine (Cognex).
While ginkgo may help treat various types of dementia, ginkgo does not appear to help prevent dementia from developing. - Vision problems in people with diabetes. There is some evidence that taking ginkgo leaf extract by mouth can improve color vision in people with retinal damage caused by diabetes.
- Vision loss (glaucoma). Taking ginkgo leaf extract by mouth for up to 12.3 years seems to improve pre-existing damage to the visual field in some people with normal tension glaucoma. However, conflicting research shows that ginkgo does not prevent glaucoma progression when taken for only 4 weeks.
- Leg pain when walking due to poor blood flow (peripheral vascular disease). Some evidence shows that taking ginkgo leaf extract increases the distance people with poor blood circulation in their legs can walk without pain. Taking ginkgo might also reduce the chance of requiring surgery. However, people with this condition may need to take ginkgo for at least 24 weeks before they see improvement.
- Premenstrual syndrome (PMS). Taking ginkgo leaf extract by mouth seems to relieve breast tenderness and other symptoms associated with PMS when started during the 16th day of the menstrual cycle and continued until the 5th day of the following cycle.
- Schizophrenia. Research shows that taking ginkgo daily in addition to conventional antipsychotic medications can reduce symptoms of schizophrenia. It may also reduce adverse effects associated with the antipsychotic medication, haloperidol.
- A movement disorder called tardive dyskinesia. Tardive dyskinesia is a movement disorder that is caused by certain antipsychotic drugs. Research shows that taking a specific ginkgo extract (EGb 761, Yi Kang Ning, Yang Zi Jiang Pharmaceuticals Ltd., Jiangsu, China) can reduce the severity of tardive dyskinesia symptoms in people with schizophrenia who are taking antipsychotic drugs.
- Vertigo and dizziness. Taking ginkgo leaf extract by mouth seems to improve symptoms of dizziness and balance disorders.
