《危氏方》记载：取乌头一两，去掉尖端；巴豆一两；硫黄、麻黄各半两；木鳖子十个。一同放入瓷器或石器中。
用水煮一天。取出洗净杂质。再用止痛药没药、乳香、当归、花蕊石各半两。像之前那样用水煮一天。取出后用皂角水清洗。再放入犬肉中煮一天。仍然用瓦片打磨干净，使其端正笔直。涂上松子油。经常靠近人体气息为妙。
凡是度量周身穴位远近分寸的方法，以病患男性取左手、女性取右手的中指第二节。内部测量两个横纹之间的距离，这段距离作为一寸。用薄竹片标记并量取分寸以便使用。或者有人手长身体短，或者身体长手短，或者人高但胸腹短，或者人矮但胸腹长。揣测穴位位置时尤其应当用心思考。凡穴位都不离开肌肉之间的缝隙，动脉之中，这是溪谷交汇之处，用来运行营卫之气，汇聚大气。其经脉粗细形状像细线，只要让针对准经脉刺入，根据方法施行补泻，就能治愈疾病了。《明堂定尺寸法》说：以八寸为一尺，以八分为一寸。因为人有高矮胖瘦不同，取穴不准。秦代扁鹊《明堂经》说：取男性左手、女性右手中指第一节为一寸。因为有人身长手短，有人身短手长，取穴不准。唐代孙思邈《明堂经》说：取患病者男性左手、女性右手的大拇指直节横纹为一寸。需要仔细斟酌，巧妙与拙劣在于人。也有一种方法，令取男性左手、女性右手中指节第二节内测量两个横纹之间的距离，这段距离作为一寸。自从依据此寸法给人针灸治病以来，多数疾病都获得了痊愈。此法有标准，现在将其定为准则。
凡是点穴时，必须使身体平直，四肢不要蜷缩。坐位点穴不要前俯后仰。站立点穴不要倾斜偏侧。坐位点穴就坐着针灸，站立点穴就站着针灸。与此相反，就不能准确找到穴位了。
又说：灸治时如果孔穴位置不正，对事情没有益处，只是白白烧坏好肉，让人徒受痛苦之苦。如果有病，先灸上部，后灸下部；先灸少处，后灸多处，都应该审慎考虑。
The *Wei Shi Fang* (Formulas of Master Wei) records: Take one liang of Aconiti Lateralis Radix Preparata (Chuanwu, 川乌), remove the tip; one liang of Crotonis Fructus (Baddou, 巴豆); half a liang each of Realgar (Xionghuang, 雄黄) and Ephedrae Herba (Mahuang, 麻黄); ten seeds of Momordicae Semen (Miezi, 木鳖子). Place them together into a porcelain or stoneware vessel.
Boil in water for one day. Remove and wash away impurities. Then add half a liang each of Myrrha (Moyao, 没药), Boswelliae Carterii Resina (Ruxiang, 乳香), Angelicae Sinensis Radix (Danggui, 当归), and Poria Cocos (Huashirui, 花蕊石) [Note: Huashirui is typically Pseudoginseng Flower Bud or similar mineral/herb mix in this context, often translated as Rhizoma Polygonati or specific stone herb, here kept as generic flower/stone herb based on text 'Hua Rui Shi']. Boil in water for one day again as before. Remove and wash with Gleditsiae Sinensis Fructus (Zaocao, 皂角) water. Then boil in dog meat for one day. Still polish clean with tile fragments until straight and neat. Coat with Pinus Massoniana Seed Oil (Songzi You, 松子油). It is best to keep it close to human body heat/qi frequently.
Whenever measuring the distance and cun (units) between acupoints on the whole body, use the second phalanx of the middle finger of the patient's left hand if male, or right hand if female. Measure internally the distance between the two transverse creases within this segment; this distance constitutes one cun. Use a thin bamboo strip to mark and measure these cun for application. Or, if someone has long hands but a short body, or a long body but short hands, or a tall person with a short chest and abdomen, or a short person with a long chest and abdomen, special attention must be paid when palpating for acupoints. All acupoints are located between the muscles, within the arteries, which are the convergence points of the xi-gu (valleys), serving to circulate Ying-Wei (Nutritive and Defensive) Qi and gather the Great Qi. The meridians are as fine as threads; simply insert the needle directly into the meridian, applying tonification or sedation according to the method, and the disease can be cured. The *Mingtang Ding Chicun Fa* (Method for Determining Cun in Mingtang) states: Eight cun make one chi; eight fen make one cun. Because people vary in height and weight, inaccurate point location may occur. Bian Que’s *Mingtang Jing* from the Qin Dynasty stated: Take the first phalanx of the middle finger of the male left hand or female right hand as one cun. However, because some have long bodies and short hands, or short bodies and long hands, point location may be inaccurate. Sun Simiao’s *Mingtang Jing* from the Tang Dynasty stated: Take the transverse crease of the proximal interphalangeal joint of the thumb of the male left hand or female right hand of the patient as one cun. This requires careful deliberation; skill or clumsiness depends on the practitioner. There is also another method: take the distance between the two transverse creases within the second phalanx of the middle finger of the male left hand or female right hand as one cun. Since using this cun method for acupuncture and moxibustion treatment, most illnesses have been successfully cured. This method is accurate and is now established as the standard.
When marking acupoints, the body must be kept straight, and the limbs should not be curled up. When marking while sitting, avoid leaning forward or backward. When marking while standing, avoid tilting to either side. If marking while sitting, perform acupuncture while sitting; if marking while standing, perform acupuncture while standing. Doing otherwise will result in missing the correct acupoint.
It is also said: If the acupoint is incorrect during moxibustion, it is of no benefit, merely burning good flesh and causing the patient unnecessary suffering. If treating an illness, moxa should be applied to the upper part first, then the lower part; applied to fewer points first, then more points. These matters should all be considered carefully.
