Native to China, the Ginkgo Biloba tree is widely cultivated and was introduced early to human history. It has various uses in traditional medicine and as a source of food.
Ginkgo improves blood flow to the brain and acts as an antioxidant. Ginkgo seems to improve blood circulation, which might help the brain, eyes, ears, and legs function better. Several ginkgo studies have shown that it can help with memory problems. It is also used for conditions that seem to be due to reduced blood flow in the brain, especially in older people. These conditions include memory loss, headache, ringing in the ears, vertigo, difficulty concentrating, mood disturbances, and hearing disorders. Ginkgo seeds contain substances that might kill the bacteria and fungi that cause infections in the body.
