"Ginkgo Biloba - Does It Really
Improve Memory?"

By Kearney Adams


The Ginkgo biloba tree has been used for thousands of years as part of traditional Chinese medicine. But does it really help improve memory? You may be surprised at the answers given below.

It is thought to be one of the oldest living trees on earth. They are very large trees with some Chinese specimens exceeding 164 feet in height.

The ginkgo trees were once commonly found in North America and Europe, but, with the exception of Ginkgo biloba, the remaining species have since become extinct.

Herbalists think its medicinal qualities are as a result of two compounds found in it, the Flavonoids and the Proanthocyanidins. Flavonoids are thought to be anti-inflammatory while Proanthocyanidins function as an antioxidant.

Ginkgo biloba also contains a compound known as Ginkgolide which may counteract the effects of a chemical known as Platelet Activating Factor (PAF). PAF is thought to promote the growth of Cancerous tumors.



Research Concerning Memory Improvement

Today, ginkgo biloba is primarily known for the effect it has on improving memory.

While early studies demonstrated hopeful results, more recent research has shown it is ineffective when it is used for memory improvement.

In one study done by the National Institute on Aging, 200 healthy adults over the age of 60 were given Gingko biloba for six weeks. At the trial's end, the researchers found no evidence it was effective in improving memory.

In a randomized, double-blind, placebo-controlled study, 230 individuals over the age of 60 in good health were recruited with the objective of determining if it improved memory in elderly individuals.

For a period of six weeks, these individuals were given either 40 milligrams of Gingko biloba, three times daily, or placebo. At the conclusion of this trial, standard memory and learning tests indicated there was no difference in memory capability between the two groups.



The Stroke Connection to the Elderly

Additionally, in another 3-year study, 118 healthy men and women over the age of 85 were recruited to see what effect this compound had in preventing memory loss in octogenarians.

These individuals were given either 240 milligrams of Gingko daily or placebo. At the end of this study, the researchers noted a small but disturbing pattern.

7 of the 118 individuals experienced TIAs (Transient Ischemic Attacks, or mini-strokes) or Strokes. The researchers were puzzled why this happened and indicated that more research in this area needs to be done.



Other Research

There ever been multiple clinical trials evaluating the effect of ginkgo biloba on a condition known as Cerebral Insufficiency. Symptoms of this condition may include confusion, absent-mindedness, difficulty concentrating, headaches, fatigue, and Depression.

It is believed Cerebral Insufficiency is caused by a lack of blood to the brain as a result of clogged blood vessels.

Although preliminary studies demonstrated its effectiveness as a treatment for this condition, further research needs to be done before any conclusions can be drawn.

There have been numerous studies indicating its usefulness as a treatment for Intermittent Claudication. With this condition, an individual experiences pain in the legs when exercising or at rest due to clogged arteries.

A clinical trial comparing the effects of taking either 120 or 240 milligrams of this supplement for this condition saw a significant improvement in those individuals taking the higher dosage.



Treatment For Dementia

In a review of 8 randomized, double-blind studies, Ginkgo biloba was found to have modest effects on the symptoms of Dementia. It was found to be equally effective as the prescription medicine Hydergine, a medicine commonly used as a treatment for Dementia.

In a subsequent analysis of 4 articles measuring its effects on cognitive function in individuals with Alzheimer's disease, it was found to be as effective as the prescription medicine Aricept, a medicine used to treat early stage and Alzheimer's.



Dosage

Dosages for this home remedy vary, and are based on the symptoms and the severity of the condition treated.

For most people, 120 to 240 milligrams split up into 2 to three doses a day is adequate.

For individuals with Alzheimer's disease, 60 to 80 milligrams 3 times daily for at least 8 weeks is beneficial.

For those with Intermittent Claudication, 60 to 80 milligrams 3 times daily for no less than 6 weeks should help.



Side Effects and Contraindications

When taken correctly, side effects from Ginkgo biloba are rare.

As it may affect blood sugar levels, Diabetics should only take it under a doctor's supervision.

Pregnant women should not take is as there is some evidence it may cause a miscarriage.

If you experience any of the following side effects, you should stop taking it immediately:

  • Fever
  • Edema
  • Joint or muscle pain
  • Swelling of blood vessels
  • Bleeding in the eye
  • Bleeding under the skin
It may increase the effects of blood thinners such as of Aspirin, Coumadin, and Ticlid resulting in uncontrolled bleeding.

Taking it with any of the thiazide diuretics is dangerous as it may cause major increases in blood pressure.

Certain herbs when taken in conjunction with this remedy may increase the risk of uncontrolled bleeding. Herbs such as: Devil's Claw, Danshen, Ginger, Garlic, Papain, Red Clover, Horse Chestnut, and Saw Palmetto for example.
