Based on the record of Miu Ci theory from Huangdi Neijing (The Yellow Emperor's Internal Classic), and incorporating the relevant discussions of medical scholars from various dynasties, this article interprets and analyzes the Miu Ci technique, the points to be needled, and the diseases can be treated. The following innovative understandings are proposed： 1) The original meaning of "Miu" in Miu Ci is "to prick in a different way from the meridians (needle the major collaterals)", not "needle left and right interchangeably". Needle left and right interchangeably is not a necessary operation in Miu Ci. 2) The stimulation sites of Miu Ci are the "four extremities" of the human body, referred to as the "major collaterals of qi", and the nail bed of the four extremities is not equivalent to the commonly reco-gnized "Jing-well points". 3) Miu Ci can treat critical illnesses, not just limited to musculoskeletal pain or mild conditions at the early stage of a disease. 4) Miu Ci is not equivalent to Luo Ci needling (pricking bloodletting therapy).
本文以《黄帝内经》缪刺诸论为研究主体，参合历代医家相关论述，对缪刺刺法、刺处、治疗病证等进行诠释分析，提出如下创新性认识：①缪刺之“缪”的本义为“异于经脉而刺（刺大络）”，而非“左右互刺”，“左右互刺”非缪刺必要操作；②缪刺的作用部位是被称为“气之大络”的人体“四末”，且四末之爪甲处并不等同于一般所认知的“井穴”；③缪刺可治疗危重之疾，而非仅局限于肌体痛症或疾病初起之轻症；④缪刺不等同于络刺。.
