Ginkgo leaf extract has been used to treat a variety of conditions such as asthma, bronchitis, fatigue, and tinnitus. It is also used to improve memory and to prevent dementia and other brain disorders. Some studies have supported its slight effectiveness. But exactly how gingko works isn’t understood. Only extract from leaves should be used. Seeds contain ginkgo toxin. This toxin can cause seizures and, in large amounts, death. Because some information suggests that ginkgo can increase the risk of bleeding, it should not be used with nonsteroidal anti-inflammatory medicines, anticoagulants, anticonvulsant medicines, or tricyclic antidepressants.
As one of the oldest tree species, gingko is also one of the oldest homeopathic plants and a key herb in Chinese medicine. The leaves are used to create capsules, tablets, and extracts, and when dried, can be consumed as a tea.
It’s perhaps best-known for its ability to boost brain health. Studies say that gingko can treat patients with mild to moderate dementiaTrusted Source, and can slow cognition decline in dementia and Alzheimer’s disease.
Recent research is looking into a component that can help diabetes, and there continue to be more studies, including an animal study that says it might influence bone healing.
