Location:
Sit upright or lie supinely with knee joints flexed; at the most obvious pressure point between ZusanliST36 (Zusanli (ST36) He-Sea Point) and ShangjuxuST37 (Shangjuxu (ST37) The Lower He-Sea Point of the Large Intestine), generally, 1.5-2 cun below ZusanliST36 (ST36).
Function:
Regulating qi and purging the internal heat.
Indications:
Acute and chronic appendicitis, indigestion, and paralysis of the lower extremities.
Prescription:
Combined use with Ashi points and ZusanliST36 (ST36) for treatment of appendicitis; and with ShangjuxuST37 (ST37), TianshuST25 (Tianshu (ST25) Front-Mu Point of the Large Intestine) and DijiSP8 (Diji (SP8) Xi-Cleft Point) for treatment of carbuncles of the intestine and appendicitis.
Methods:
Insert the needle perpendicularly to 0.5-1 cun deep; needling response: local soreness and distension, radiating toward the dorsum of the foot; moxibustion: using 5-7 moxa-cones, or mild moxibustion for 10-15 min.
