Herbal Drugs in Mirror of Alzheimer’s Disease

Abstract

Commercially available Ginkgo biloba leaf extracts may lack specificity as to the binding of copper and zinc ions in human cells. This might be the reason why Ginkgo extracts have no predictable and clinically significant benefit for people with dementia or cognitive impairment. A novel generation of herbal drugs is proposed as antioxidant and metal chelator in the treatment of Alzheimer's disease.
