Vinpocetine is a man-made chemical similar to a substance found in the periwinkle plant (Vinca minor). In Europe, it's sold as a drug called Cavinton. Vinpocetine might increase blood flow to the brain and protect brain cells (neurons) against injury. People use vinpocetine for memory, dementia, stroke, hearing loss, and many other conditions, but there is no good scientific evidence to support most of these uses.We hereby confirm that, to the best of our knowledge, this product is free of BSE/TSE.
