[Objective]To systematically sort out the theoretical basis of the concept of"cooked chewing"eating health preservation in traditional Chinese medicine(TCM)and Taoist literature,explain its specific practical methods,provide theoretical basis and operational guidelines for contemporary health preservation practice.[Methods]Based on the research method of philology,this paper systematically analyzed the bamboo and silk classics of Han Dynasty and the medical classics handed down from ancient times such as Huangdi Neijing,Yangxing Yanminglu,Qianjin Yaofang,combined with the Taoist health preservation literature contained in Daozang,and used the basic theory of TCM and Taoist health preservation theory to theoretically explain the health preservation method of"cooked chewing".[Results]It reveals that the health preservation method of"cooked chewing"is based on the theory of Taoist knocking teeth.The method of producing body fluid by knocking teeth up and down is related to the relationship between kidney saliva,spleen saliva and kidney teeth in the theory of TCM,and then sums up the specific operation specifications such as"cooked chewing should be closed to the genus of Zhongqing Tiangu"and"cooked chewing should be up to thirty-six times".[Conclusion]As a kind of health preservation method derived from knocking teeth,"cooked chewing"transforms the complex knocking teeth of Taoism into simple chewing behavior.The concept of health preservation contained in it is of great significance to the practice of contemporary health preservation.
