Nervous system diseases in the central nervous system, peripheral nervous system and autonomic nervous system lead to sensory, motor, consciousness, and autonomic dysfunctions, which are the main manifestations of these diseases. They have a marked impact on a patient’s life and work. In traditional medicine, cinnamon has the function of “ nourishing the primary yang, warming the spleen and stomach, removing internal cold, and promoting blood circulation.” Modern research suggests that cinnamon has anti-oxidation, free radical scavenging, anti-inflammation, antiintermittency,and anti-ulcer effects. Recent studies have shown that cinnamon has a medicinal effect on nervous system diseases, such as Alzheimer’s disease, Parkinson’s disease and multiple sclerosis. Therefore, this paper summarizes the research progress and potential medicinal value of cinnamon for the treatment of nervous system diseases.
