Indications and Usage

Ginkgo (Ginkgo biloba) is one of the oldest living tree species and its leaves are among the most extensively studied botanicals in use today. Unlike many other medicinal herbs, ginkgo leaves are not frequently used in their crude state, but rather, in the form of a concentrated, standardized ginkgo biloba extract (GBE). In Europe, GBE is among the best-selling herbal medications and it ranks within the top five of all prescriptions written in France and Germany.

Ginkgo has been used in traditional medicine to treat circulatory disorders and enhance memory. Scientific studies throughout the years lend support to these traditional uses. Emerging evidence suggests that GBE may be particularly effective in treating ailments associated with decreased blood flow to the brain, particularly in elderly individuals. Laboratory studies have shown that GBE improves blood circulation by dilating blood vessels and reducing the stickiness of blood platelets.

Ginkgo leaves also contain two types of chemicals (flavonoids and terpenoids) believed to have potent antioxidant properties. Antioxidants are substances that scavenge free radicals -- damaging compounds in the body that alter cell membranes, tamper with DNA, and even cause cell death. Free radicals occur naturally in the body, but environmental toxins (including ultraviolet light, radiation, cigarette smoking, and air pollution) can also increase the number of these damaging particles. Free radicals are believed to contribute to a number of health problems including heart disease and cancer as well as Alzheimer's disease and other forms of dementia. Antioxidants such as those found in ginkgo can neutralize free radicals and may reduce or even help prevent some of the damage they cause.

Ginkgo is widely used in Europe for treating dementia. It was used originally because it improves blood flow to the brain. Now further study suggests it may work directly to protect nerve cells that are damaged in Alzheimer's disease. A number of studies have found that gingko has a positive effect on memory and thinking in people with Alzheimer's or vascular dementia.


Ginkgo is not generally used in children. Initial results often take 4 - 6 weeks, but should grow stronger beyond that period. Memory impairment and cardiovascular function: Generally, 120 mg daily in divided doses, standardized to contain 24 - 32% flavone glycosides (flavonoids or heterosides) and 6 - 12% triterpene lactones (terpenoids). If more serious dementia or Alzheimer's disease is present, up to 240 mg daily, in 2 or 3 divided doses, may be necessary.


GBE is generally considered to be safe, and side effects are rare. In a few cases, gastrointestinal upset, headaches, skin reactions, and dizziness were reported.


If you take gingko, you should stop taking it at least 36 hours prior to surgery or dental procedures due to the risk of bleeding complications. Tell your doctor or dentist that you take gingko.


People who have epilepsy should not take gingko, because there is concern that it might cause seizures.


Pregnant and breastfeeding women should not take gingko.
