Analysis of the rules of acupoint selection along meridians in the treatment of insomnia by guasha therapy.

This article focuses on analyzing the patterns of meridian and acupoint selection in guasha therapy, a traditional Chinese medicine scraping technique, for treating insomnia. Using data mining on 119 studies, the research identifies Xinshu (BL15), Baihui (GV20), and Shenmen (HT7) as the most frequently used acupoints, primarily located on the Bladder meridian of foot-taiyang and the Governor vessel, which are core meridians in this therapy. The study highlights common acupoint combinations such as Xinshu-Pishu (BL20) and Xinshu-Pishu-Shenmen, reflecting traditional Chinese medicine principles of regulating viscera and balancing Yin and Yang to improve sleep quality. The findings provide a standardized reference for clinical practice and future research, emphasizing the importance of meridian compatibility and acupoint synergy in guasha therapy for insomnia.
