I was just reading a book about studying and the writer advises drinking "Ginkgo" to boost alertness and blood circulation. However on looking it up Wikipedia says it may cause;
increased risk of bleeding, gastrointestinal discomfort, nausea, vomiting, diarrhea, headaches, and restlessness
Has anyone tried Ginkgo? Are it's
memory enhancer and anti-vertigo agent
worth the side-effects?

For more information, I've posted teh following article. I'm still interested to know what others think and if anyone has tried it.

More and more Americans are turning to supplements like Ginkgo Biloba that claim to boost brain power! Experts say there are key terms to look for on the label to make sure you’re getting the biggest books for you bucks! Medical Reporter Stephanie Stahl has the details.

Madeline Arruda has a mind-boggling schedule and relies on a daily dose of Ginkgo Biloba to keep her memory in check.

“It’s a ‘thumbs-up’ for me in my life!” said Arruda.

The pills claim to boost memory, mental clarity, concentration, alertness and focus, but studies on Ginkgo are conflicting.

Ginkgo expert Steven DeKosky told us, “Some suggest that it does have an effect on memory and others have not found that effect.”

Dr. Tod Cooperman withConsumerLab looked at dozens of supplements and put 13 of the most popular to the test, only six passed.

Dr. Cooperman explained, “Either the right amount of Ginkgo wasn’t there or they were using a very poor quality.”

He also said while most supplements have trace levels of lead, he was concerned about what he found in three of the brands tested.

“It’s actually more lead than we’ve ever seen in supplements,” said Dr. Cooperman. “We don’t know if the levels in these products is enough to cause injury or symptoms in adults. It’s just something you want to avoid!”

In fact, Olympia Labs, one of the companies flagged for lead by ConsumerLab, is now recalling a line of their Ginkgo Biloba supplements.

Another manufacturer, Canadian Sun, said, it is in “total compliance with all the Canadian regulations and that its products are highly tested in accordance with very strict guidelines.”

Dr. Cooperman said the studies showed Ginkgo had a positive effect on memory when combined with specific amounts of certain antioxidants.

Look for products that are standardized to contain 24% flavonol-glycosides and 6% terpene lactones. At least you know those companies know what they’re shooting for.

Madeline Arruda said from now on she’ll remember to check the label, but is going to continue taking the supplement.

“I do believe it has helped me,” said Arruda.

The F.D.A. does not regulate supplements or set lead levels for them. Experts say you should read the label carefully and look specifically for Ginkgo extract.

I used to take a ginko/guarana tablet to get through exams/life/all night parties. I found it exceptionally beneficial to my memory retention.

In the book I was reading it said 120mg daily was recommended. How expensive is it?

It depends how much terpene lactone it is standardized to, I imagine those 360x120mg have a low standardization?

"Ginkgo Biloba Extract 120mg Equivalent to: 6000mg
Providing:
Ginkgo Flavonglycosides 28.8mg*
Terpene Lactones 7.2mg*"

That is the statistics for the pills I mentioned. Not sure if this is considered low or not.

I got about 4months worth of ginkgo pills off ebay and they did squat all.

But my mum got some from malaysia, it was quite expensive, something like £50 for 4 small cylinders of ginkgo in the form of powder. And after having it in the evening, (without intending to realise i.e. continuing as normal), I did quite a bit of biology work, when I layed down on my bed I could actually recall almost everything I read that evening, I could actually visualise the question it self!

So yeah, if you are going to buy ginkgo, buy the expensive ones. The cheaps ones on ebay which you drink have less than 10% gingko. Gingko is very hard to grow, something like 6 years I've heard (is this true?)

edit: Oh sorry, the stuff my mum bought was gingseng, which is very similar to gingko (I think)

I bought some Gingko pills from Holland and Barrats before my exams and they gave me severe headaches.

I think it depends on each person.
