What is Gingo Biloba? What is it used for?

Answer 1

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.

Based on studies conducted in laboratories, animals, and humans, professional herbalists may recommend ginkgo for the following health problems:

Dementia and Alzheimer's Disease
Ginkgo is widely used in Europe for treating dementia. The reason that ginkgo is thought to be helpful for preventing or treating these brain disorders is because it improves blood flow in the brain and because of its antioxidant properties. Although many of the clinical trials have been scientifically flawed, the evidence that ginkgo may improve thinking, learning, and memory in people with Alzheimer's disease (AD) has been highly promising.

Clinical studies suggest that ginkgo provides the following benefits for people with AD:

Improvement in thinking, learning, and memory
Improvement in activities of daily living
Improvement in social behavior
Fewer feelings of depression
One recent study also found that ginkgo may be as effective as leading AD medications in delaying the symptoms of dementia in people with this debilitating condition. In addition, ginkgo is sometimes used preventively because it may delay the onset of AD in someone who is at risk for this type of dementia (for example, family history).

Eye problems
The flavonoids found in ginkgo may help halt or lessen some retinal problems (that is, problems to the back part of the eye). Retinal damage has a number of potential causes, including diabetes and macular degeneration. Macular degeneration (often called age-related macular degeneration or ARMD) is a progressive, degenerative eye disease that tends to affect older adults and is the number one cause of blindness in the United States. Studies suggest that gingko may help preserve vision in those with ARMD.

Intermittent Claudication
Because ginkgo is reputed to improve blood flow, this herb has been studied in people with intermittent claudication (pain caused by inadequate blood flow [atherosclerosis] to the legs). People with intermittent claudication have difficulty walking without suffering extreme pain. An analysis of eight published studies revealed that people taking ginkgo tend to walk roughly 34 meters farther than those taking placebo. In fact, ginkgo has been shown to be as effective as a leading medication in improving pain-free walking distance. However, regular walking exercises are more beneficial than ginkgo in improving walking distance.

Memory Impairment
Ginkgo is widely touted as a "brain herb" and is commonly added to nutrition bars and fruit smoothies to boost memory and enhance cognitive performance. Researchers recently reviewed all of the high-quality published studies on ginkgo and mild memory impairment (in other words, people without Alzheimer's or other form of dementia), and concluded that ginkgo was significantly more effective than placebo in enhancing memory and cognitive function. Despite the encouraging findings, some researchers speculate that more high-quality research, involving larger numbers of people, is needed before ginkgo can be recommended as a memory enhancer to otherwise healthy adults.

Tinnitus
Given that nerve damage and certain blood vessel disorders can lead to tinnitus (the perception of ringing, hissing, or other sound in the ears or head when no external sound is present), some researchers have investigated whether ginkgo relieves symptoms of this hearing disorder. Although the quality of most studies was poor, the reviewers concluded that ginkgo moderately relieves the loudness of the tinnitus sound. However, a recent well-designed study including 1,121 people with tinnitus found that ginkgo (given 3 times daily for 3 months) was no more effective than placebo in relieving symptoms of tinnitus. Given these conflicting findings, the therapeutic value of ginkgo for tinnitus remains uncertain. In general, tinnitus is a very difficult problem to treat. Talk to your doctor about whether a trial of ginkgo to alleviate this frustrating symptom may be safe and worthwhile for you.

Other
In addition to these health problems, professional herbalists may also recommend ginkgo for a variety of other ailments including altitude sickness, asthma, depression, disorientation, headaches, high blood pressure, erectile dysfunction, and vertigo.

Plant Description

Ginkgo biloba is the oldest living tree species. A single tree can live as long as 1,000 years and grow to a height of 120 feet. It has short branches with fan-shaped leaves and inedible fruits that produce a strong odor. The fruit contains an edible inner seed.

Although Chinese herbal medicine has used both the ginkgo leaf and seed for centuries, modern research has focused on the standardized Ginkgo biloba extract (GBE), which is prepared from the dried green leaves. This extract is highly concentrated and much more effective in treating health problems (particularly circulatory ailments) than the leaf alone.


--------------------------------------------------------------------------------


What's It Made Of?

More than 40 components of ginkgo have been identified but only two are believed to be responsible for the herb's beneficial effects -- flavonoids and terpenoids. As described earlier, flavonoids (such as quercetin) have potent antioxidant effects. Laboratory and animal studies have shown that flavonoids protect the nerves, heart muscle, and retina from damage. Terpenoids (such as ginkgolides) improve blood flow by dilating blood vessels and reducing the stickiness of platelets.

How to Take It

Pediatric

There are no known scientific reports on the pediatric use of ginkgo. Therefore, it is not currently recommended for children.

Adult

Initial results often take 4 to 6 weeks, but should continue to accumulate beyond that period. You may not see any dramatic changes for six months.
GBE: 120 mg daily in two or three divided doses of 50:1 extract standardized to 24% flavone glycosides (flavonoids). If more serious dementia or Alzheimer's disease is present, up to 240 mg daily in two or three divided doses may be necessary.
Tincture (1:5): 2 to 4 mL three times a day


--------------------------------------------------------------------------------


Precautions

The use of herbs is a time-honored approach to strengthening the body and treating disease. Herbs, however, contain active substances that can trigger side effects and interact with other herbs, supplements, or medications. For these reasons, herbs should be taken with care, under the supervision of a practitioner knowledgeable in the field of botanical medicine.

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

Because gingko decreases platelet aggregation (stickiness), there is some concern that it may increase risk of intracranial (brain) hemorrhage. In fact, there have been several reports of bleeding complications associated with ginkgo use. However, it is not clear whether ginkgo or another factor (such as the combination of ginkgo and blood-thinning medications including aspirin) caused the bleeding complications.

Pregnant and breastfeeding women should avoid using ginkgo preparations. In addition, ginkgo use should be discontinued at least 36 hours prior to surgery due to the risk of bleeding complications.

Do not ingest Ginkgo biloba fruit.

Possible Interactions

If you are currently being treated with any of the following medications, you should not use ginkgo without first talking to your healthcare provider:

Anticonvulsant medications
High doses of Ginkgo biloba could decrease the effectiveness of anticonvulsant therapy in patients taking carbamazepine or valproic acid to control seizures.

Blood-thinning medications
Ginkgo has blood-thinning properties and therefore should not be used if you are taking anticoagulant (blood-thinning) medications, such as aspirin, clopidogrel, dipyridamole, heparin, ticlopidine, or warfarin.

Cylosporine
Ginkgo biloba may be beneficial during treatment with cyclosporine because of its ability to protect cell membranes from damage.

Monoamine oxidase inhibitors (MAOIs)
Ginkgo may enhance the effects (both good and bad) of antidepressant medications known as MAOIs, such as phenelzine and tranylcypromine.

Papaverine
The combination of papaverine and ginkgo may be effective for the treatment of erectile dysfunction in patients who do not respond to papaverine alone.

Thiazide diuretics
Although there has been one literature report of increased blood pressure associated with the use of ginkgo during treatment with thiazide diuretics, this interaction has not been verified by clinical trials. Nevertheless, you should consult with your healthcare provider before using ginkgo if you are taking thiazide diuretics.

Trazodone
Additionally, there has been a report of an adverse interaction between ginkgo and trazodone, an antidepressant medication, that resulted in an elderly patient going into a coma.

Answer 2

Gingo Biloba may be the oldest seed plant in the world, midway between a fern and a conifer. It traces its ancestry almost unchanged via Gingo Adiantoides, which flourished in the Tertiary Period (56 million years ago) all the way back to the Permian period, 270 million years ago.

Now recent trials among mountaineers have indicated that extract of Gingo Biloba seems to help alleviate symptoms of altitude sickness. I tried it on a recent climbing trip to Bolivia. And yes, I think it did help. I will be using it again next time I go climbing.
