    Neurogenesis is decreased in the absence of nerve growth factor (NGF). It would be beneficial to discover substances that stimulate neurogenesis without NGF, given the high molecular weight and brief half-life of NGF. This work aims to assess the neurogenesis of ginger extract (GE) combined with superparamagnetic iron oxide nanoparticles (SPIONs) without NGF. Based on our research, GE and SPIONs start neurogenesis before NGF. In comparison to the control group, GE and SPIONs dramatically reduced the length and quantity of neurites, according to statistical analysis. Our findings also indicated that SPIONs and ginger extract together had an additive impact on one another. The total number significantly increased with the addition of GE and nanoparticles. In comparison to NGF, the mixture of GE and nanoparticles significantly enhanced the total number of cells with neurites (by about 1.2-fold), the number of branching points (by about 1.8-fold), and the length of neurites. The difference between ginger extract and nanoparticles with NGF was significant (about 3.5-fold), particularly in the case of cells with one neurite. The results of this study point to the possibility of treating neurodegenerative disorders via the combination of GE and SPIONs without NGF.
