法三首 论一首
初灸风市，次伏兔，次犊鼻，次膝目，次三里，次上廉，次下廉，次绝骨。
凡八穴，风市穴∶令病患起，正身平立，垂两手直下，舒十指掩着两髀，便点手中指头
，髀大筋上灸百壮，逐轻重灸之，轻者不可减百壮，重者一穴五六百壮。伏兔穴∶令病患累
夫端坐，以病患手夫横掩膝上，夫下旁与曲膝头齐上旁侧，夫际当中央是，灸百壮，亦可五
十壮。犊鼻穴∶在膝头盖骨上际外角平处，以手按之，得节解是；一法云在膝头下近外三骨
箕踵中，动脚，以手按之，得窟解是；灸五十壮。膝目穴∶在膝头骨下两旁陷者宛宛中是，
灸百壮。三里穴∶在膝头骨节下一夫附胫骨外是；一法云在膝头骨节下三寸，人有长短大小，
当以病患手夫度取。灸百壮。上廉穴∶在三里下一夫，亦附胫骨外是，灸百壮。下廉穴∶在
上廉下一夫，亦附胫骨外是，灸百壮。绝骨穴∶在足外踝上一夫；一云四寸是，灸百壮。凡
此诸灸，不必一顿灸尽壮数，可日日报灸之，三日之中，令尽壮数为佳，凡病一脚灸一脚，
病两脚便灸两脚也。凡脚弱病多着两脚。一方云∶觉脚异便灸三里及绝骨各一处，两脚异者
合四穴灸之，多少逐病轻重，大要虽病轻，不可减百壮，不瘥，速令以次灸之，多则佳。
脚疼，三阴交三百壮，神良。一云灸绝骨最要。论曰∶有人得之不以为事，不觉忽然入
腹，腹肿心热，其气大上，遂至绝命。当知微觉有异，即须大灸之，乃得应手即瘥。亦依旧
支法存灸之梁丘、犊鼻、三里、上廉、下廉、解溪、太中、阳陵泉、绝骨、昆仑、阴陵泉、
三阴交、足太阳、复溜、然谷、涌泉、承山、束骨等凡一十八穴。旧法多灸百会、风府、五
脏六腑俞募，顷来灸者悉觉引气向上，慎不得灸，以上大忌之。
又∶灸足十指奇端去奇一分，两足凡八穴，名曰八冲极下气。足十指端名曰气端。日灸
三壮，其八冲可日灸七壮，气下即止，艾炷小作之。
三种取穴方法和一篇论述。
首先灸风市穴，其次灸伏兔穴，再次灸犊鼻穴，接着灸膝目穴，然后灸足三里穴，再灸上廉穴，随后灸下廉穴，最后灸绝骨穴。
以上共八个穴位。风市穴的定位方法：让患者站立，身体端正平直，双手自然下垂，十指张开覆盖在大腿两侧，此时手中指尖所指之处，即是大腿外侧大筋上的穴位，在此处施灸一百壮（艾炷），根据病情轻重调整灸量，轻症不少于百壮，重症每穴可灸五至六百壮。伏兔穴的定位方法：让患者端坐，屈膝，以患者的手横放按在膝盖上方，手腕下方边缘与弯曲膝盖的最高点齐平，手腕中间正对的位置即是该穴，在此处施灸一百壮，也可灸五十壮。犊鼻穴的定位方法：位于膝盖髌骨上缘外侧角的平坦处，用手按压此处，能感到关节缝隙即为准确位置；另一种说法认为在膝盖下方靠近外侧三块骨头之间、脚背肌腱隆起处的凹陷中，活动脚踝时用手按压，感到有窟窿感即为准确位置，在此处施灸五十壮。膝目穴的定位方法：位于膝盖骨下方两侧的凹陷深处，在此处施灸一百壮。足三里穴的定位方法：位于膝盖骨节下一横指宽处，紧贴胫骨外侧；另一种说法认为在膝盖骨节下三寸处，由于人体有高矮胖瘦之分，应当以患者的手宽作为度量标准来取穴。在此处施灸一百壮。上廉穴的定位方法：在足三里穴下方一横指宽处，同样紧贴胫骨外侧，在此处施灸一百壮。下廉穴的定位方法：在上廉穴下方一横指宽处，同样紧贴胫骨外侧，在此处施灸一百壮。绝骨穴的定位方法：在外踝尖上方一横指处；另一种说法认为是四寸处，在此处施灸一百壮。
上述各穴的艾灸，不必一次性灸完规定的壮数，可以每天分次进行艾灸，最好在三天内灸完规定的总壮数。通常左脚患病就灸左脚，双脚患病则灸双脚。一般来说，脚弱病多发生在双脚。有一种说法认为：感觉脚部异常时就应灸足三里和绝骨穴各一处，若双脚均有异常则合起来灸这四个穴位，灸量多少根据病情轻重而定，大体原则是即使病情较轻，也不得少于百壮；如果未痊愈，应迅速依次灸其他穴位，灸量多一些效果更佳。脚部疼痛，可灸三阴交穴三百壮，疗效极佳。另一种说法认为灸绝骨穴最为关键。
论述说：有人得了这种病不以为意，不知不觉病邪忽然侵入腹部，导致腹部肿胀、心中烦热，气机逆乱向上冲，甚至导致死亡。因此应当知道，只要微微感觉到异常，就必须大力施灸，才能应手而愈。也可以依照支法存的方法，灸梁丘、犊鼻、足三里、上廉、下廉、解溪、太冲（原文“太中”疑为“太冲”之误，但依原文保留或注疑，此处按原文翻译为太中）、阳陵泉、绝骨、昆仑、阴陵泉、三阴交、足太阳经相关穴位、复溜、然谷、涌泉、承山、束骨等共计十八个穴位。旧有的方法多灸百会、风府以及五脏六腑的俞穴和募穴，近来发现灸这些穴位会导致气机上逆，务必不要灸，这是上方的大禁忌。
另外：灸足十个脚趾尖端奇骨边缘一分处，双足共八个穴位，名为“八冲”，具有极降气的作用。足十趾尖端称为“气端”穴。每日灸三壮，“八冲”穴每日可灸七壮，待气下行后即可停止，艾炷要做得小一些。
Three methods of acupuncture/moxibustion point selection and one treatise.
First, moxa the Fengshi (GB31) acupoint; second, the Futu (ST32); third, the Dubi (ST35); fourth, the Ximu (an extra point); fifth, the Zusanli (ST36); sixth, the Shanglian (ST34); seventh, the Xiaolian (ST37); and eighth, the Jiegu (GB39).
There are eight acupoints in total.
Fengshi (GB31): Instruct the patient to stand upright with the body straight and hands hanging naturally by the sides. Spread the ten fingers to cover both thighs. The tip of the middle finger points to the location on the large tendon of the thigh. Moxa 100 cone-moxa units here, adjusting according to severity: mild cases should not receive less than 100 units, while severe cases may receive 500 to 600 units per acupoint.
Futu (ST32): Instruct the patient to sit upright with knees bent. Place the patient's hand horizontally over the knee. The lower edge of the wrist aligns with the upper side of the bent knee cap, and the center of the wrist corresponds to the acupoint. Moxa 100 units, or alternatively 50 units.
Dubi (ST35): Located at the outer corner level with the upper margin of the patella. Pressing with the hand reveals the joint gap, confirming the location. Another method states it is located near the outer three bones below the knee, in the depression between the tibial tuberosity and the fibular head; moving the foot while pressing reveals a hollow sensation. Moxa 50 units.
Ximu (Extra Point): Located in the deep depression on both sides below the knee bone. Moxa 100 units.
Zusanli (ST36): Located one *cun* (width of the patient's thumb) below the knee joint, attached to the outer side of the tibia. Another method states it is three *cun* below the knee joint; due to variations in height and size among individuals, measure using the patient's hand width. Moxa 100 units.
Shanglian (ST34): Located one *cun* below Zusanli (ST36), also attached to the outer side of the tibia. Moxa 100 units.
Xiaolian (ST37): Located one *cun* below Shanglian (ST34), also attached to the outer side of the tibia. Moxa 100 units.
Jiegu (GB39): Located one *cun* above the lateral malleolus; another source says four *cun*. Moxa 100 units.
For all the aforementioned moxibustions, it is not necessary to complete the prescribed number of cone-moxa units in one session. It is advisable to perform moxibustion daily, ideally completing the total number within three days. Generally, if one foot is diseased, moxa that foot; if both feet are diseased, moxa both. Foot weakness often affects both feet. One method suggests: upon feeling abnormalities in the feet, moxa one site each of Zusanli (ST36) and Jiegu (GB39); if both feet are abnormal, moxa these four sites in total. The quantity depends on severity, but as a general rule, even for mild disease, do not reduce below 100 units. If not cured, proceed rapidly to moxa the subsequent acupoints; more moxa is better. For foot pain, moxa Sanyinjiao (SP6) 300 units, which is highly effective. Another view holds that moxa Jiegu (GB39) as the most critical point.
Treatise: Some people neglect this condition until it suddenly ascends into the abdomen, causing abdominal swelling and heart heat, with qi rushing upward severely, potentially leading to death. Therefore, one must know that upon sensing any slight abnormality, vigorous moxibustion is required to achieve immediate cure. One may also follow the method of Zhi Facun, moxing the Liangqiu (ST34), Dubi (ST35), Zusanli (ST36), Shanglian (ST34 - note: text likely implies distinct points or repetition in context, translated as listed), Xiaolian (ST37), Jiexi (ST41), Taichong (LV3 - text says "Taizhong", likely typo for Taichong or referring to a specific local point, kept as Taizhong per text), Yanglingquan (GB34), Jiegu (GB39), Kunlun (BL60), Yinlingquan (SP9), Sanyinjiao (SP6), Taiyang Bladder Meridian points, Fuliou (KI7), Ran Gu (KI2), Yongquan (KI1), Chengshan (BL57), Shugu (BL65), totaling eighteen acupoints. Old methods frequently moxa Baihui (GV20), Fengfu (GV16), and the Shu and Mu points of the five zang and six fu organs. Recently, practitioners have observed that moxing these points draws qi upward; therefore, they must not be moxaed, as this is a major taboo for the upper body.
Additionally: Moxa the distal ends of the ten toes, one fen away from the odd bone end. There are eight such points on both feet, named "Ba Chong" (Eight Rushes), which powerfully descend qi. The tips of the ten toes are named Qiduan (EX-UE11). Moxa three units daily on Qiduan, and seven units daily on Ba Chong. Stop when the qi descends. Use small cone-moxa units.
