Ginkgo Biloba

The ginkgo tree is one of the rare trees that has no close relations on earth (considered a living fossile), and grows wild only in two areas of China, although there are cultivated groves worldwide. It’s a deep rooted, deciduous tree that grows from 60 to over 100 feet tall. Some are thought to be over 2,500 to 3,000 years old, and their longevity can be partially attributed to disease and insect resistance as well as their ability for form aerial roots on the undersides of branches that grow down towards the ground.

Medicinal Claims

Traditionally, the seeds are used as a food and are an ingredient in some Chinese dishes that are favorites in other countries as well. Also called white nuts, they are thought by some to have aphrodisiac qualities. However, some people are highly allergic to the outer coating on the seeds and break out in rashes and blisters when their skin comes into contact with it. Also, children can be poisoned by these seeds and could experience convulsions.

As with many other supplements and herbal remedies, ginkgo biloba has been in use for thousands of years and is still one of the favorite supplements today. It is used for many different conditions, and among the most promising is its affect on various vascular diseases, disorders, and dementias. It is often used to boost mental functions and ease vascular damage due to chemotherapy. It is also often used to treat altitude sickness.

There is strong evidence in favor of ginkgo biloba for treatment of claudication symptoms. Although it may not be as effective as exercise, ginkgo could be a good solution for those unable to exercise. Again, some studies with better control and planning are warranted and needed. There are many other medicinal claims for ginkgo, but other than the ones currently said to show some promise, none of the others has panned out so far.

Warnings and Interactions

Patients with certain circulation disorders may have bad side effects from ginkgo biloba, as well as people who take aspirin and anticoagulants. Those who take MAOI (monoamine oxidase inhibitors) should not take ginkgo, nor should pregnant or nursing mothers. Besides an increase in bleeding, side effects include nausea, diarrhea, vomiting, dizziness, and headaches. Others have reported restlessness and other gastrointestinal discomfort, increases in blood pressure, and even the possible loss of fertility.

The seeds themselves are poisonous, and should not be eaten. There is a risk of convulsive seizures, loss of consciousness, and even death.

Diabetics and those suffering from hypoglycemia should avoid ginkgo except under the advice and monitoring of a physician.
