Analysis of the connotation of'the back is called Taichong'in Huangdi Neijing
The term'Taichong'appeared 12 times in Huangdi Neijing,but it has different meanings.'Taichong',which serves as the Taichong acupoint and Chong meridian,possesses the clear connotation.However,in'the front is called Guangming,and the back is called Taichong'from Su Wen·Yinyang Lihe Lun,the implication of Taichong is not explicit.Three main viewpoints exist,including'the kidney meridian and Chong meridian merging and flourishing''Ren meridian and Chong meridian forming a yin-yang relationship in the abdomen and back',and'locating the north and belonging to yin'.But these views were not self-consistent or comprehensive.By exploring the word,context and medical theories,this article holds that this'Taichong'is located in the back and lower part.In terms of its function,Taichong can not only store energy,but also ascend and nourish'Guangming'.The essence of the human body's material foundation and the kidney of the organs in traditional Chinese medicine are both concrete expressions of'Taichong'.Clarifying the connotation of'the back is called Taichong'also provides important theoretical support for clinical treatment principles,such as nourishing the essence to benefit the spirit,and communicating the heart and the kidney.
