Ginkgo Not a Help for Brains
A study in the Journal of the American Medical Association reports that the herbal supplement Ginkgo biloba does not slow the rate of mental decline. Ginkgo is one of the most recommended and widely used supplements for people showing mild cognitive impairment. But researchers at the University of Pittsburgh found no evidence that it had any effect on changes in thinking. The study followed more than 3,000 people over the age of 72 who had normal thinking or only mild impairment at the start of the experiment. The researchers found no evidence to show a prevention of decline or an improvement of cognitive performance. If you are using this supplement, be sure to talk with your doctor about its benefits and effects on your health.
