Ginkgo biloba, the ancient oriental remedy already known to improve blood circulation, has also been shown to improve memory and overall brain function in those with dementia. Scientists at Oxford University in the UK assessed 33 clinical trials of Ginkgo dating back to the 70s and found patients who took up to 200 mg of the supplement every day for up to a year did better on cognitive and memory tests. Scientists believe that the supplement slows down the degenerative process of the brain. Ginkgo causes blood vessels to dilate, improving blood flow to the brain, and also thins the blood, making it less likely to clot. It may also contain antioxidant effects, protecting nerve cells against biological ‘rusting’. But you are advised to consult a doctor before beginning a course of the supplement as it is not suitable for everyone, especially if you have an underlying blood condition.
