Zhu Danxi stated: All moxibustion methods for the neck region are good, but the "riding bamboo horse" moxibustion method is particularly crucial. This prevents illness before it manifests. First, instruct the patient to rest their elbows on a table with arms and wrists extended and back straight. Take a thin strip of bamboo (Bamboo Strip) and measure from the end of the wrist crease on the left side for men or the right side for women, placing it against the skin until the tip of the middle finger. Do not include the fingernail in the measurement. Then, take a bamboo pole and have the patient disrobe and straddle it securely, maintaining an upright posture. Two people should lift the pole so that the patient's feet do not touch the ground, while two others support the patient to prevent falling. Next, take the measured bamboo strip from the wrist and place it vertically against the bamboo pole starting from the end of the coccyx where the patient sits, extending up along the spine to the end of the strip as the standard. Mark this point with ink. This is merely to find the midpoint, not the actual acupoint. Take another thin bamboo strip and measure the length of the middle finger joint, using the width of two transverse knuckles as the standard. Cut a piece to this length. Based on the principle of left for men and right for women, measure this distance outward from both sides of the previously marked point. These two locations are the moxibustion points. Moxa cones (Moxa Cones) of five or seven moxa moxibustions (Moxibustion) should be applied to each point; do not over-moxa. Regardless of where the carbuncle (Carbuncle) occurs, including mastitis (Mastitis), this method can be used, and there will be no failure to heal. Another view states: if the ulcer (Ulcer) appears on the left, moxa the left; if on the right, moxa the right; if severe, moxa both sides. This is because these two points lie on the pathway of the Heart Meridian (Heart Meridian). The classics state: "All pain, itching, sores, and ulcers belong to Heart Fire." It also says: "The Heart governs blood vessels." If Heart Qi stagnates, blood cannot flow smoothly, leading to rebellion within the muscle tissue and causing sores. Moxing these points regulates Heart Fire and promotes blood circulation, thereby achieving efficacy, even rescuing patients from death.
Liu Wansu believed that for moxibustion and acupuncture treating sores and ulcers, one must distinguish the meridian regions, the abundance or scarcity of Qi and Blood, and the proximity or distance of acupoints. For sores emerging from the back, select from the five acupoints of the Foot-Taiyang Bladder Meridian (Foot-Taiyang Bladder Meridian): Tonggu (Tonggu, BL65) (located on the lateral side of the fifth toe, about the width of a leek leaf from the corner of the nail); Shugu (Shugu, BL65) (located in the depression anterior to the metatarsophalangeal joint on the lateral side of the fifth toe); Kunlun (Kunlun, BL60) (located in the depression between the lateral malleolus and the calcaneus); Weizhong (Weizhong, BL40) (located in the center of the popliteal fossa where the artery pulses). For sores emerging from the temples, select from the five acupoints of the Foot-Shaoyang Gallbladder Meridian (Foot-Shaoyang Gallbladder Meridian): Qiaoyin (Qiaoyin, GB44) (located at the tip of the fourth toe, about the width of a leek leaf from the corner of the nail); Xiaxi (Xiaxi, GB43) (located in the depression anterior to the metatarsophalangeal joint between the fourth and fifth toes); Linqi (Linqi, GB41) (located in the depression posterior to the metatarsophalangeal joint of the fourth toe); Yangfu (Yangfu, GB38) (located four cun above the lateral malleolus, anterior to the end of the fibula, three fen forward); Yanglingquan (Yanglingquan, GB34) (located one cun below the knee, in the depression on the lateral aspect). For sores emerging from the beard area, select from the five acupoints of the Foot-Yangming Stomach Meridian (Foot-Yangming Stomach Meridian): Lidui (Lidui, ST45) (located at the tip of the second toe, about the width of a leek leaf from the corner of the nail); Neiting (Neiting, ST44) (located in the depression between the second and third toes); Xangu (Xangu, ST43) (located in the depression posterior to the metatarsophalangeal joint between the first and second toes); Chongyang (Chongyang, ST42) (located on the dorsal foot, in the bone interval artery, three cun from Xangu); Jiexi (Jiexi, ST41) (located one cun and five fen posterior to Chongyang, in the depression above the ankle). For sores emerging from the head/brain, select only the Juegu point (Juegu, GB39) (located three cun above the lateral malleolus in the artery).
Another theory suggests: when a carbuncle or ulcer first appears, one must first apply moxibustion to the head of the lesion to open its "door." Then, observe which meridian the affected area belongs to. Internally, administer herbs corresponding to that meridian to guide the treatment to the exterior. Externally, use acupuncture and moxibustion on the Shu points of that meridian to drain the pathogenic factors. Treating both internally and externally leaves no room for the pathogen.
