Ginkgo biloba does not slow cognitive decline: study

The herbal supplement ginkgo biloba does not slow cognitive decline, a study published Tuesday in the Journal of the American Medical Association (JAMA) said.

Researchers from the University of Pittsburgh analyzed data in an eight-year randomized, double-blind placebo-controlled trial called the Ginkgo Evaluation of Memory (GEM) study, for which half of the 3,069 participants were given daily doses of ginkgo biloba and the other half were given a placebo.

"In the United States and particularly in Europe, ginkgo biloba is perhaps the most widely used herbal treatment consumed specifically to prevent age-related cognitive decline," the report of their findings in JAMA said.

"We found no evidence for an effect of G biloba on global cognitive change and no evidence of effect on specific cognitive domains of memory, visual-spatial construction, language, attention and psychomotor speed, and executive functions," the study said.
