In one study, people with generalized anxiety were treated with either mg or mg of ginkgo or a placebo. Some research shows that ginkgo may help treat anxiety, though this is likely due to its antioxidant content. A review of animal studies suggests that supplementing with ginkgo may help treat symptoms of depression Mice who received ginkgo before an unavoidable stressful situation were less emotionally affected by the stress than the group that did not receive the supplement.
More research is needed to better understand the relationship between ginkgo and how it may affect depression in humans. More research is needed. Very little research has investigated how ginkgo relates to vision and eye health.
However, early results are promising. Another review of two studies evaluated the effect of ginkgo extract on the progression of age-related macular degeneration. More research is needed to determine whether ginkgo can increase vision capacity or slow the progression of degenerative eye disease. Some early research shows that supplementing with ginkgo may increase blood flow to the eyes but not necessarily improve vision. In traditional Chinese medicine, ginkgo is a very popular treatment for headaches and migraines However, depending on the root cause of the headache, it may help.
If a headache or migraine is caused by excessive stress, ginkgo may be useful. On the contrary, some migraines are caused by the excessive dilation of blood vessels. In this situation, ginkgo may have little to no effect. Just be aware that it may not necessarily help. Because of its ability to increase blood flow and reduce inflammation, ginkgo may be an effective treatment for some types of headaches. Some research indicates that ginkgo may improve symptoms of asthma and other inflammatory respiratory diseases like COPD.
This is attributed to the anti-inflammatory compounds in ginkgo, which may allow for reduced inflammation of the airways and increased lung capacity One study in 75 people evaluated the use of ginkgo extract alongside glucocorticosteroid medication therapy for managing asthma symptoms The levels of inflammatory compounds in the saliva of those who received ginkgo were significantly lower than those who received traditional medication alone.
Another study in people evaluated the use of a mixture of Chinese herbs, which included ginkgo, for treating COPD symptoms. Those who used the herbal formula reported a considerable reduction in cough and bronchitis at a three-month follow-up, compared to the control group At this point, it cannot be determined if this improvement can be attributed to ginkgo alone, or if it was a synergistic effect of the other herbs used in the treatment group formula.
While these results are encouraging, more research on this specific application of ginkgo is needed. Ginkgo may treat symptoms associated with respiratory diseases because of its anti-inflammatory effects. Preliminary research indicates that ginkgo may help treat both the physical and psychological symptoms of premenstrual syndrome PMS. Interestingly, the placebo group in this study also experienced a slight reduction in PMS symptoms, though it was much lower at 8.
The therapeutic properties of the ginkgo plant are said to include treatment for blood disorders and memory problems, enhancement of cardiovascular function and to improve eye health. Gingko contains high levels of flavonoids and terpenoids, antioxidants that provide protection against oxidative cell damage from harmful free radicals.
In this way, antioxidants are believed to help reduce the risk of cancer. Also known as the maidenhair tree, ginkgo is one of the oldest species of tree in the world. The trees can grow more than feet tall and can live for over 1, years.
Some trees in China are said to be over 2, years old. The extract can be taken as a supplement, and the dried leaves of the plant can be used to make tea. Ginkgo biloba may offer a range of health benefits, including improving cognitive function. Traditional uses are wide-ranging, but not all of them have been confirmed by research. There is some evidence indicating that ginkgo can help people with dementia, although more studies are required to confirm this. Other research, published in JAMA , similarly concluded that EGb was safe to use and possibly effective in stabilizing and possibly improving cognitive and the social functioning patients with dementia for between 6 and 12 months.
Researchers believe that ginkgo improves cognitive function because it promotes good blood circulation in the brain and protects the brain and other parts from neuronal damage.
However, other research suggests that ginkgo may not improve memory among people who are healthy. Ginkgo may help alleviate the symptoms of anxiety. A study published in the Journal of Psychiatric Research , found that people with generalized anxiety disorder who took ginkgo experienced better anxiety relief than those who took a placebo. The purpose of this review is to provide a synthesis of the mechanisms of action, clinical indications, and safety of Ginkgo biloba extract.
