Ginko Dosing

Ginkgo is an herb. The leaves are generally used to make “extracts” that are used as medicine. However, a few medicines are made from the seed, but these are not well studied.

Ginkgo is often used for memory disorders including Alzheimer’s disease. 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. Some people use it for other problems related to poor blood flow in the body, including leg pain when walking (claudication), and Raynaud’s syndrome (a painful response to cold, especially in the fingers and toes).

How does it work?

Ginkgo seems to improve blood circulation, which might help the brain, eyes, ears, and legs function better. It may slow down Alzheimer’s disease by interfering with changes in the brain that interfere with thinking.

Alzheimer’s disease and other forms of 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.
