Abstract
In recent years, insomnia has gradually become a common disease in society, which seriously affects people's quality of life. At present, with the deepening of research on intestinal microbiota-gut-brain axis in Western medicine, many studies suggest that regulating the gastrointestinal tract can treat brain-related diseases. It is found that brain-gut-bacteria axis plays an important role in the prevention and treatment of primary insomnia. At present, although the clinical treatment of insomnia with Western medicine can improve the insomnia symptoms of patients to a certain extent, there are still obvious adverse reactions, such as anxiety and depression, drug addiction, etc., so long-term oral drug therapy cannot be carried out. Traditional Chinese medicine (TCM) and acupuncture techniques have certain therapeutic effects on insomnia. TCM believes that the brain and gastrointestinal system are connected through the meridian, and the pathophysiology is closely related. This paper will discuss the theory and feasibility of TCM for the treatment of insomnia from the pathological relationship between brain-gut axis, intestinal flora and insomnia.
