Background:: Spinal cord injury (SCI) leads to severe sensory, motor, and autonomic dysfunction with limited treatment options. Ginsenosides, the primary bioactive compounds derived from Panax ginseng, have demonstrated neuroprotective potential in SCI. This systematic review aims to evaluate the preclinical evidence regarding the multi-target mechanisms of ginsenosides in SCI. Methods:: A comprehensive literature search was conducted following PRISMA guidelines across PubMed, Web of Science, and Google Scholar up to January 2025. Of the 385 identified articles, 22 studies met the inclusion criteria, which focused on the pharmacological effects of ginsenosides in SCI using both in vivo and in vitro models. Data on mechanisms, models, and outcomes were systematically synthesized. Results:: Ginsenosides exerted multi-target neuroprotective effects in SCI models, including antiinflammatory actions via suppression of TLR4/NF-κB and MAPK signaling, leading to reduced TNF-α, IL-1β, and IL-6, antioxidant activity through Nrf2/HO-1 pathway activation, enhancing SOD, CAT, and GSH, anti-apoptotic effects via ASK1/JNK inhibition, lowering caspase-9/3 and Bax while elevating the Bcl-2/Bax ratio, regulation of autophagy by activating PI3K/Akt to prevent excessive self-digestion, promotion of neural repair through upregulation of neurotrophic factors (NGF, bFGF, BDNF, and GDNF) and extracellular matrix components (laminin, fibronectin), inhibition of spinal cord edema via increased AQP4 expression, and facilitation of nerve regeneration by promoting astrocyte-to-neuron conversion and olfactory ensheathing cell migration. Discussion:: The findings highlight the synergistic mechanisms of ginsenosides in addressing key pathological processes in SCI, including inflammation, oxidative stress, apoptosis, and impaired neural regeneration. While preclinical evidence underscores their therapeutic promise, the translational potential requires validation through rigorous clinical trials to confirm efficacy, safety, and applicability in humans. Conclusion:: Ginsenosides exhibit multi-target neuroprotective effects in SCI models, positioning them as promising candidates for therapeutic development. Further clinical studies are essential to advance their application in SCI treatment.
