Studies have shown that ginsenosides can protect nerve cells from the harm of neurodegenerative diseases by reducing the deposition of Aβ, inhibiting the phosphorylation of tau protein, alleviating neuroinflammation, combating oxidative stress, promoting neurite outgrowth, and regulating the levels of neurotransmitters (Huang, Li, et al. 2019; Huang, Liu, et al. 2019; Radad et al. 2011). This evidence concerns the gene MAPT and neurodegenerative disease.
