“面口合谷收”机制研究概况

Research Overview of the Mechanism of “Treatment of Orofacial Diseases by Using Hegu(L14)”

摘要: 合谷穴位于手背，第一二掌骨间靠近第二掌骨桡侧中点，为手阳明大肠经原穴，具有通经活络，清热解表，镇静止痛等作用。《四总穴歌》中记有“面口合谷收”，表示面部口角部等处疾患可通过针刺合谷穴治疗并可取得良好疗效，但目前对于针刺合谷穴治疗口面部疾患的作用机理尚未明确，因此本文从穴位特性、经脉循行、经络理论、神经中枢系统等传统医学和现代医学角度对“面口合谷收”的作用机理进行探讨，为“面口合谷收”的临床应用提供理论依据进一步指导。

Abstract: The Hegu(L14) is located on the back of the hand, between the first and second metacarpal bones, near the middle point of the radial side of the second metacarpal bone. It is the original acupoint of the Large Intestine Channel of Hand-Yangming and has the functions of unblocking the meridian, promoting circulation, clearing heat, and relieving surtace symptoms, as well as calming and relieving pain. The “Four Major Meridian Song” records “treatment of orofacial diseases by using Hegu(L14)” indicating that disorders in the facial and oral areas can be treated by acupuncture at the Hegu(L14) and achieve good therapeutic effects. However, the mechanism of action of acupuncture at the Hegu(L14) in treating disorders of the face and mouth is not yet clear. Therefore, this article explores the mechanism of action of “treatment of orofacial diseases by using Hegu(L14)” from traditional medical and modern medical perspectives such as acupoint characteristics, meridian circulation, meridian theory, and the nervous central system, in order to provide theoretical basis for the clinical application of “treatment of orofacial diseases by using Hegu(L14)” and further guidance.
