Through collecting the relative records about "Nishun"(contradiction and consistency between pulse conditions and severity of illness) in pulse taking for acupuncture treatment in ancient literature of traditional Chinese medicine

and combining with the understanding about pulse taking in Lingshujing(Miraculous Pivot) and later generations' clinical application

the different meanings of "Nishun" are analyzed in the present article. It is concluded that pulse taking during acupuncture treatment is considered the fundamental principle in the age of Lingshujing

and if the pulse conditions are contradicted to the illness

acupuncture treatment is prohibited. The practitioners of the later generations also emphasized that only by ensuring no contradiction between the pulse conditions and illness

could we operate acupuncture treatment. These greatly expand the contents of "Nishun" when taking pulse conditions for acupuncture treatment. All of these have a positive significance to the further research on pulse taking for acupuncture treatment.
