脐疗作为中医外治法之一,具有激发经气、疏通经络、调节元气及脏腑功能的功效。高树中教授发展四关理论，强调脐关的重要性，提出兼具诊断与治疗功能的脐心穴、脐肾穴、脐肝穴、脐肺穴及脐胃穴，并充分挖掘外治药物特点，构建脐疗用药框架，创立遣方精妙、以简驭繁的高氏脐灸方。高教授临床常用隔药灸脐法，其操作要点包括艾炷大小适宜、药末纳脐适量、施灸时间适度等，并灵活采用针刺脐部法、贴敷脐部法、按摩脐部法等其他脐疗方法。脐疗在防治诸多疾病方面显示出较好的临床疗效，值得推广应用。

As one of the external therapies in Traditional Chinese Medicine (TCM), umbilical therapy possesses the effects of stimulating meridian qi, dredging meridians, and regulating primordial qi (yuan qi) as well as the functions of zang-fu organs. Professor Gao Shuzhong has developed the “Four Passes Theory” (Si Guan Li Lun), emphasizing the importance of the “umbilical pass” (Qi Guan). He proposed specific acupoints with both diagnostic and therapeutic functions, including Umbilical Heart Point (Qi Xin Xue), Umbilical Kidney Point (Qi Shen Xue), Umbilical Liver Point (Qi Gan Xue), Umbilical Lung Point (Qi Fei Xue), and Umbilical Stomach Point (Qi Wei Xue). Professor Gao has fully explored the characteristics of externally applied TCM herbs, constructed a framework for medication in umbilical therapy, and created the “Gao-style Umbilical Moxibustion Prescriptions”—exquisitely formulated recipes that achieve complex therapeutic effects through simple approaches.​In clinical practice, Professor Gao mainly adopts the “herb-separated umbilical moxibustion” technique, with key operational points including appropriate size of moxa cones, proper dosage of herbal powder filled into the umbilicus, and moderate duration of moxibustion. Additionally, he flexibly applies other umbilical therapy methods such as umbilical acupuncture, umbilical application (tapping), and umbilical massage. Umbilical therapy has shown favorable clinical efficacy in preventing and treating various diseases, making it worthy of promotion.
