Su Gong stated: Whenever Hongjiaojiao (a disease characterized by swelling and weakness of the lower legs and feet) occurs, it presents with Yin and Yang, Exterior and Interior patterns. Treatment must be tailored to the specific symptoms; one should not blindly follow ancient prescriptions. Treating a Yin pattern as if it were Yang, or addressing an Exterior condition by rescuing the Interior, will lead to misjudgment of deficiency and excess, resulting in grave danger.

If the disease originates from the Yin aspect, it begins at the medial side of the big toes of both feet, ascending along the medial aspect of the shins and into the knee interior. It manifests as stiff numbness and insensitivity, or swelling that first appears in the calf muscles (Shuan), then spreads toward the Juegu point. All such cases should be treated according to... [text missing, likely referring to acupoint moxibustion].

Acupoint Descriptions:
Yanglingquan (BL34): Two points located in the depression below the lateral condyle of the tibia.
Juegu (GB39): Two points located in the depression at the end of the bone above the lateral malleolus; alternatively described as one cun above Juegu.
Fengshi (GB31): Two points located between the two tendons on the lateral aspect of the thigh, where the tip of the middle finger touches when standing upright with arms hanging down. The *Huangdi Sanbu Zhenjiu Jing* does not list Fengshi; this may be an alias for Huantiao (GB30), though its origin is unclear.
Kunlun (BL60): Two points located in the depression behind the lateral malleolus and above the calcaneus.
Yangfu (GB38): Two points located half a cun anterior and slightly inferior to Juegu. Xu’s *Mingtang Jing* does not list Juegu but lists Yangfu: two points three cun below the knee, lateral to the fibula, between the tendons of the little toe. The *Huangdi Sanbu Zhenjiu Jing*, Volume Bing, describes Yangfu as four cun above the lateral malleolus, anterior to the fibular head, three fen anterior to the end of Juegu, which differs from the above description.
Shanglian (ST35 variant/extra point): Two points three cun below Zusanli (ST36).
Tiaokou (ST38): Two points two cun below Shanglian.
Xialian (ST37 variant/extra point): Two points one cun below Tiaokou.
Taichong (LR3): Two points two cun proximal to the metatarsophalangeal joint of the big toe. The *Huangdi Sanbu Zhenjiu Jing*, Volume Bing, refers to Dubi (ST35)... The *Mingtang Jing* does not list Ximu.
Ququan (LR8): Two points... The *Huangdi Sanbu Zhenjiu Jing*, Volume Bing, locates Ququan in the depression medial to the tibia below the knee. In the *Huangdi Sanbu Zhenjiu Jing*, it is also known as Zhongdu (SP7) and belongs to the Foot-Taiyin Spleen Meridian.
Fuliu (KI7): Two points above the medial malleolus...
Yangwei (Extra point): Two points one cun posterior to the medial malleolus, within the pulsating tendon, consistent with Xu’s description.
Taiyin (SP6 variant?): Two points eight cun above the medial malleolus, in the depression below the bone, consistent with Xu’s description.
Taiyin Qiao (Extra point): Two points in the depression anterior to the medial malleolus, consistent with Huang’s description.
Weizhong (BL40): Two points in the center of the popliteal crease, consistent with Xu and Su’s descriptions.
Chengjin (BL57): Two points in the depression between the muscle bellies of the gastrocnemius... consistent with Xu and Su’s descriptions.
Yongquan (KI1): Two points in the sole of the foot...

The aforementioned acupoints are essential and should not be moxaed arbitrarily. The most critical ones are Zusanli (ST36), Juegu (GB39), Chengjin (BL57), Taichong (LR3), Kunlun (BL60), and Yongquan (KI1). Patients may undergo moxibustion on these points.

Su Gong stated: For early-stage Hongjiaojiao presenting with muscle spasms (Zhuanjin), moxa Chengshan (BL57) and Chengjin (BL57). For hiccups (Yueni), moxa Yongquan (KI1). If pain radiates from the head to the back, accompanied by chills and fever resembling malaria, or if there is lumbar pain, moxa Weizhong (BL40). For headache, neck stiffness, and back pain accompanying general body pain, apply moxibustion; strict adherence to standard acupoint locations is not required.

Furthermore, during severe exacerbations of Hongjiaojiao, moxibustion and acupuncture are contraindicated on the upper body (waist and above), as drawing pathogenic wind upward can be fatal. After the acute qi disturbance subsides, if residual symptoms remain, moxibustion is permissible. Moxibustion is only suitable in winter; it is contraindicated in spring and summer. Acupoints below Fengshi (GB31) are appropriate for moxibustion.

Additionally, if rebellious qi strikes the heart and does not recede, urgently moxa the palm 21 moxa cones (3 x 7); the qi will subside. If the qi does not recede and suffocation occurs, drink hot fermented soybean wine to expel the pathogen, which will cure the condition. If the pathogen persists, administer one sheng (approx. 200ml) of warm cow urine until diarrhea ensues. Even three to five doses are beneficial.

If moxibustion has been applied to the feet but chest qi remains stagnant causing fullness and oppression, moxa Jianshi (PC5) 50 cones. This point is located two cun distal to the transverse wrist crease, between the two tendons.

If chest qi is scattered and a bounding, jumping pulse is felt below the heart, descending and branching into the medial thighs, causing anxiety and palpitations, use manual manipulation on... [text missing] Zusanli (ST36)...

If heart and abdominal qi stabilize but the lateral thighs and knees feel oppressed, moxa Xiyan (EX-LE5) 7 cones. This point is located in the depression lateral to the patellar ligament, below the knee cap. If recurrence occurs, moxa 3 additional cones.

Even individuals not suffering from Hongjiaojiao who experience thigh and knee pain and oppression will find immediate relief from moxibustion on this point. It is a highly effective point but should not needled or over-moxaed; limit to 7 cones or fewer.

If soreness and pain affect all ten toes and spread to the dorsum of the foot, moxa the midpoint of the nail bed margin of each toe 3 cones for immediate resolution.

If pain and oppression occur on the sides of the big or little toes, with a sensation of flowing pulse ascending into the thigh and abdomen, moxa 3 cones adjacent to the affected toe for immediate resolution. (All extracted from Volume Upper).

Tang Dynasty Commentary: If pain starts at the interphalangeal joints of the fingers and extends slightly into the arm, moxa the painful area between the fingers 7 cones to stop the pain.

If chest and heart qi are full, and despite moxibustion on body and leg acupoints and herbal decoction intake, the qi still fails to descend, causing extreme irritability and a sense of impending death, moxa the central depression below the soles of both feet 7 cones each. The qi will descend. This point is extremely critical; do not moxa frequently. Only apply 7 cones in extreme emergencies. The aforementioned moxibustion methods have been utilized...
