abstract: Ninjin-yoei-to (NYT), a Kampo medicine, has ameliorative effects on cognitive dysfunction via enhancing cholinergic neuron activity. To explore an efficacy of NYT administration for prevention and cure of Alzheimer's disease, here we examined the effect of NYT on amyloid β<sub>1-42</sub> (Aβ<sub>1-42</sub>)-induced neurodegeneration in the dentate gyrus. A diet containing 3% NYT was administered to mice for 2 weeks and human Aβ<sub>1-42</sub> was intracerebroventricularly injected. Neurodegenera
