Researchers evaluated the roots of Berberis aetnensis C. Presl. and Berberis libanotica Ehrenb. ex C.K. Schneid. for their potential use in treating Alzheimer's disease. They tested the roots for anticholinesterase and antioxidant properties. This is the first study to evaluate these plants for these properties. The results indicated that both plants could be useful in the treatment of AD. This study highlights the potential of natural compounds in the treatment of Alzheimer's disease.
