Medicinal properties: Ginkgo has a long history of use in treating blood disorders and memory issues. It is best known today as way to potentially keep your memory sharp. Laboratory studies have shown that ginkgo improves blood circulation by opening up blood vessels and making blood less sticky. It is also an antioxidant.
For those reasons, ginkgo may improve vein and eye health. Although not all studies agree, ginkgo may help treat dementia (including Alzheimer disease) and intermittent claudication, or poor circulation in the legs. It may also protect memory in older adults.
Ginkgo leaves contain flavonoids and terpenoids, which are both antioxidants. In your body, harmful particles called free radicals build up as you age, and may contribute to heart disease, cancer, and Alzheimer disease. Antioxidants like those found in ginkgo fight off free radicals, and stop them from damaging DNA and other cells.
