New Study: Taking Ginkgo Biloba Does Not Improve Memory

A new study has found that Ginkgo biloba, known as a natural way to enhance memory, was shown to be unable to improve memory, attention, or problem solving in healthy individuals. Researchers from the University of Hertfordshire in the UK say they found “zero impact” on cognitive function, regardness of the age of the people, the dose taken, or the length of time taking the supplements.

In Europe and the US, ginkgo supplements are among the top-selling herbal medicines. Extracted from leaves of the ginkgo biloba tree, Americans spent more than $300 million dollars on the supplement in 1998.

The study involved 230 volunteers over age 60 who were physically and mentally healthy. Half took the recommended dosage of 40 milligrams of ginkgo three times a day for at least four weeks, while the rest took a placebo. No significant differences between those taking ginkgo and those taking placebo were found, the study says. The study appears in this week’s Journal of the American Medical Association.

“Our findings show that taking Gingko biloba supplements at any age to boost memory have no impact at all — and may be a waste of time and money.”

The paper, published September 24 in the journal Human Psychopharmacology: Clinical and Experimental, involved a meta-analysis of 13 randomized control trials of more than 1,000 healthy individuals across all ages.
