有人长期患有脚弱且身体消瘦。后来灸了足三里、绝骨穴，而脚部恢复如常。更加相信黄君针灸图所说的绝骨穴治疗脚疾神效是可信的。同僚因脚肿灸承山穴，一个穴位结痂干燥，另一个穴位数月不愈。不明白其中的原因。难道是调养失当吗？这里没有列出单方歌诀：风毒导致的脚弱痹证，取肩井及大椎穴。风市穴与足三里穴，百壮艾灸不必怀疑。
《千金方》灸治脚弱共有八个穴位。病在一只脚则灸一只脚，两只脚患病则灸两只脚。凡是脚弱病，都灸双脚。（见脚部病症部分）如果未能全部施灸，可以先灸风市、犊鼻、足三里、绝骨穴，也有效。或者无效时，应当按照上述方法施灸。（但肩井穴不可多灸）。
阳跷穴，治疗香港脚（脚气病）肾气不足。（明）上昆仑穴，治疗恶血风气引起的肿痛。脚肿。承山穴，治疗香港脚膝部肿胀。（见腰部脚部病症部分）。小肠俞穴，治疗脚肿。短气。食欲不振。（明云：不食，烦热疼痛）。然谷穴，治疗足背肿胀。不能着地行走。
我的母亲长期患病。夏季脚突然肿胀。旧传夏天不调理足部，不敢用艾灸。我随意将针放在火中烧红，在足三里穴刺入。微微见血。反复数次。其肿胀像失去一样消退。我素来患有脚肿，见此奇效，也用火针刺之。第二天，肿胀也消除了。何其迅速啊！后来也经常灸此穴。凡是治疗脚肿，应当先灸足三里，然后灸阳跷等穴位即可。另外我患香港脚指缝溃烂。每次用茶末撒敷即愈。后来再次溃烂并肿胀，用茶末无效。肿胀逐渐蔓延至脚背上。我认为是香港脚所致，私下担忧。拄着拐杖才敢行走。偶然卖药的人看见说，可以取床席下的灰尘撒敷。照他说的撒敷后痊愈。这东西不值一文，却能治愈令人担忧的疾病，怎么可以忽视呢。

A person who previously suffered from weak legs and emaciation later moxibusted Zusanli (ST36) and Jiexu (GB39), and his legs returned to normal. This further confirms that what Master Huang stated in his Acupuncture and Moxibustion Chart—that Jiexu (GB39) is miraculous for treating foot diseases—is indeed credible. An official colleague, suffering from swollen feet, moxibusted Chengshan (BL57). One acupoint's sore dried up quickly, while the other took months to heal. The reason is unknown. Was it perhaps due to improper care? The following single-prescription verse states: For wind-toxin causing weak and bi-affected legs, use Jianjing (GB21) and Dazhui (GV14). Fengshi (GB31) and Zusanli (ST36); hundred burns are sufficient without doubt.
Qianjin Fang lists eight acupoints for moxibustion to treat leg weakness. If the disease is in one leg, moxa only that leg; if both legs are diseased, moxa both legs. Generally, for all cases of leg weakness, both legs should be moxibusted. (See section on foot diseases.) If not all points can be treated, first moxa Fengshi (GB31), Dubi (ST35), Zusanli (ST36), and Jiexu (GB39), which is also effective. If ineffective, then follow the method described above. (However, do not over-moxa Jianjing (GB21).)
Yangqiao (BL59) treats Kidney Qi deficiency associated with Hongjiaojiao (Jamaica Foot/Grain Attack). Shang Kunlun (BL60) treats swelling and pain caused by bad blood and wind qi. Swollen feet. Chengshan (BL57) treats knee swelling in Hongjiaojiao. (See section on waist and foot diseases.) Xiaochangshu (BL28) treats swollen feet. Shortness of breath. Poor appetite. (Ming commentary: Anorexia, irritability, heat, and pain.) RanGu (KI2) treats swelling of the dorsum of the foot. Inability to walk on the ground.
My mother was chronically ill. In mid-summer, her feet suddenly swelled. Old tradition says not to treat the feet in summer, so I dared not use moxa. I casually placed a needle in the fire until hot and punctured the Zusanli (ST36) acupoint. A slight amount of blood appeared. I repeated this several times. The swelling disappeared as if lost. I have always suffered from swollen feet. Seeing this miraculous effect, I also used a red-hot needle. The next day, my swelling also subsided. How rapid! Later, I often moxibusted this point. For treating swollen feet, one should first moxa Zusanli (ST36), followed by Yangqiao (BL59) and other acupoints. Additionally, I suffered from interdigital erosion due to Hongjiaojiao (Jamaica Foot/Grain Attack). Each time, applying tea powder resolved it. Later, it eroded again and swelled. Tea powder was ineffective. The swelling gradually spread to the dorsum of the foot. I attributed it to Hongjiaojiao (Jamaica Foot/Grain Attack) and worried privately. I could only walk with a cane. A medicine seller saw me and said, "You can take dust from under the bed mat and apply it." Following his advice, I applied it and healed. This item is worthless, yet it can cure a distressing illness. How can it be ignored?
