Ginsenoside Rh2 (Rh2) is a ginseng derivative used in Chinese traditional medicine. We investigated whether Rh2 can help prevent Alzheimer’s disease symptoms and examined underlying mechanisms. We injected Rh2 into tg2576 Alzheimer’s disease model mice and looked for behavioral improvement and senile plaque reduction in brain slices. We measured amyloid precursor protein (APP) metabolism species changes, amyloid beta40 and 42 levels and β, γ secretase activity in primary hippocampal neurons. By living cell staining, we detected surface and endocytosed APP.
