This popular supplement as the Chinese plant extract of ginkgo biloba, are now widely used as an aid to improve the functioning of the brain.But, as the results of research conducted with the support of the US National Center for auxiliary and alternative medicine, this drug virtually prevents loss of memory, but can increase the risk of strokes.According MedPortal.ru, report on the results of this study published in the journal Neurology.

According to the authors said the research work, the results need to be confirmed by new, larger studies.At the same time, some independent observers believe that it is necessary to focus not on the therapeutic properties of Ginkgo biloba, and on the dangerous side effects caused by this drug.
