Dementia is a tragic condition where the brain begins to degrade and people lose their ability to remember things properly. Much of this is caused by oxidative stress and the lack of blood flow to unused parts of the brain where memory is stored. Salvia can be a highly effective remedy to stave off dementia, because it has certain vasodilatory properties that increase blood flow in small capillaries and larger blood vessels. This can significantly slow the onset of dementia, and boost your cognitive abilities as you age. Salvia is also widely available across the world.
