Ginkgo is effective for increasing cognitive ability, helping memory, increasing concentration capacity, reducing mental fog, helping depression, and increasing energy and vitality. Ginkgo is for cerebral vascular insufficiency and works by increasing blood flow into the head, brain and body, and getting the blood across the blood brain barrier. As one gets older, blood flow to the brain and to peripheral tissue decreases with these resulting symptoms. Ginkgo can be a wake call for those with this system dysfunction. Diminished cerebral circulation can also result in vertigo, ringing in the ear, Alzheimer's symptoms, forgetfulness and depression. Ginkgo can help all of this. Depression in the elderly may not e a neurotransmitter problem, but a cerebral vascular issue in which Ginkgo is indicated. Ginkgo is famous in assisting memory, focus and cognition. while it may help one to study, help memory and cognitive thinking, it works best when this vascular problem is present, especially with the elderly.

Ginkgo stimulates circulation throughout the body and can help those who run cold (Raynaud's syndrome), help cold hands and feet and warm one up. Peripheral circulatory deficiency such as that found with diabetes may also be helped with Ginkgo. ginkgo also thinks blood by diminishing platelet-aggregating factor.
