Abstract

Over the years, the safety of traditional Chinese medicine (TCM) has received widespread attention, especially the central nervous system-related adverse reactions. Indeed, the complexity of TCM has limited the widespread application of TCM. The article summarizes the main components associated with neurotoxicity, including alkaloids, terpenes, flavonoids, saponins, proteins, and heavy metals, by reviewing the literature on the neurotoxicity of TCM. It has been established that the neurotoxicity mechanisms mainly include mitochondrial damage, oxidative damage, inhibition of cell proliferation (including transcriptional and DNA damage), changes in cell membrane permeability, and apoptosis. By reviewing the latest literature, this paper provides the foothold for follow-up studies and can assist clinicians in preventing neurotoxicity via rational and safe TCM drug use.

Keywords: material basis; neurotoxicity; toxic mechanism; traditional Chinese medicine.
