Efficacy & Actions

Jiache belongs to the Foot Yangming Stomach Meridian. It dispels wind and clears heat, opens the lock and unblocks the collaterals. It is a key point for treating facial deviation, facial spasm, facial pain, toothache, and trismus. The even reinforcing-reducing technique is commonly used. First documented in Lingshu · Xieqi Zangfu Bingxing. "Jia" refers to the cheek area; "Che" means chariot or vehicle. The subtle essence of grain from the Stomach Meridian is transported upward to the head through this point, like a vehicle carrying goods – hence the name Jiache (Jaw Chariot). It is also known as "Quya," "Jiguan," "Guichuang," and "Yache." If a condition causes mouth deviation and eye歪斜, making facial muscles appear uncoordinated or distorted, or if it occurs after a stroke, regular massage of Jiache combined with exercise therapy can produce special therapeutic effects. (1) Common Point for Facial Disorders: This point excels at dispelling facial wind pathogens and opening the orifices, and is commonly used for local facial conditions such as facial deviation, facial pain, facial spasm, trismus, and temporomandibular arthritis. It is particularly effective for facial deviation – the primary point for this condition. The Yulong Ge states: "Facial deviation is most distressing; Dicang is wonderfully combined with Jiache – reduce on the left if deviation is to the right, reduce on the right if deviation is to the left." The Qianjin Yifang records: "Jiache treats locked jaw and mutism with inability to speak." It is one of the most frequently used local points for facial paralysis. A classical case from the Yuan Dynasty physician Luo Tianyi: Minister Shi, aged 68, had wind-cold invade his left cheek – the right cheek became tense and the mouth deviated to the right. Moxibustion was applied to Dicang (7 cones) and Jiache (14 cones) on the left cheek, followed by warm hand application on the right cheek, combined with a modified Shengma decoction – he recovered after several doses (Weisheng Baojian). (2) Specific Point for Toothache: This point belongs to the Stomach Meridian, which enters the upper teeth. Located near the teeth, it is highly effective for toothache and is the most commonly used local point for dental pain, effective for both upper and lower toothache. The Great Compendium records: "It treats stroke with locked jaw, mutism, aphonia, jaw pain, cheek swelling, and inability to chew." The Lingguang Fu states: "Moxibustion on Jiache cures toothache." It is more commonly used for lower toothache, while Xiaguan is preferred for upper toothache.

Contraindications

This point is often needled using the penetrating method toward Dicang (ST-4). Needle angle should be carefully controlled to avoid piercing the oral mucosa.
