针法有二，用针直入肉中曰刺。将针尖斜入皮肤向上一拨，随以手摄出恶血曰挑。刮法有四，
有用蛤壳者，有用瓷盅者，有用麻KT 者，（惟刮臂用。）有用铜钱者。凡刮，或蘸清水，或盐水，或香
油。余见刮瘟疫者，则用小枣蘸烧酒刮之，刮出紫疙瘩如熟椹，随用针斜挑破，摄出血，再另刮
出疙瘩挑之，刮毕挑止。原其用枣
蘸酒之意，取其以火攻火固已，不如易以蓖麻油蘸刮，如无，用麻汁（捣蓖麻仁稍加水，取浓汁。）
更捷。余见刮挑者，往往待瘟邪入里，现谵狂等症方用之，初感即用此方当更善也。至于瘟疫，
或有咽喉诸症则刺少商穴。（刺法穴道并见下虾蟆瘟。）或体厥脉厥等症则刺少商穴，并十指上薄肉
（靠指甲边一韭叶宽处。）当中刺之血出，如血不出，可摄出之皆效。
刮针穴道 颈项后当中，刮一道；
两旁左右大筋上，各刮一道；左右两肩软肉处，（靠肩井。）各刮一道；两肩下脊背上软肉处，各刮
一道；脊骨两旁，竖刮（自脖下至腰。）各两道；脊后胁间肋缝中软肉处，左右各刮数道；前侠旁软
肉处，斜刮各一道；前胁间肋缝中软肉处，左右各刮数道。每处如刮出紫疙瘩，随用针挑破，摄
血。
吐法近今多不讲，而抑知实有奇效也。吴又可止言邪在胸膈，欲吐不吐者方用此方，而抑知
瘟疫不论日数，忽得大吐，甚是吉兆，将欲汗解也。吴太史德 宿病胃痛，痛极则吐，偶感瘟症，
十余日，正危急间，又犯宿疾，胃口大痛，移时继以
呕吐，困顿不止。从皆惶遽莫措，求余诊视，余曰∶无妨，可勿药，有喜，不久当汗解矣。众以
余言始定。至夜，果大汗而愈。盖吐中即有发散之意，彼触动沉 而吐者，尚能发瘟疫之汗，则
涌吐之功又安可没也耶！
仙传吐法 治一切瘟疫、伤寒、伤风、伤酒、伤食，饮百沸汤半碗，以手
揉肚，再饮再揉，直至腹无所容，用鸡翎探吐，吐后煎葱汤饮之，覆衣取汗，甚捷。初得病用之
更宜。
萝卜子汤吐法 凡邪实上焦，或痰食气逆不通等症，皆可吐。可代瓜蒂、三圣散。萝卜子捣
碎，温汤和搅，徐饮之，少顷即吐，或吐不尽，必从下行。
又法 食盐少许，炒红，入滚水，宁稍
淡勿过咸，取半碗，渐次加增饮，自然发吐，以祛病为度。治食伤痞闷、膈痛、手足逆冷、尺脉
全无，兼治冷气、鬼气、蛊毒。又法∶烧盐对热童便，三饮而三吐之，治干霍乱。
又法 治积食胸闷，不宜汗下者，淡豉、食盐，水煎服，取吐。
针法有两种，将针垂直刺入肌肉中称为“刺”。将针尖斜着插入皮肤并向上一拨，随即用手捏取排出恶血称为“挑”。刮法有四种，有用蛤壳的，有用瓷盅的，有用麻布条的（仅用于刮手臂），有用铜钱的。凡是刮痧，可以蘸清水、盐水或香油。我见过刮治瘟疫的人，用小枣蘸烧酒来刮，刮出像熟桑葚一样的紫红色疙瘩，随即用针斜挑破，挤出血液，再另处刮出疙瘩并挑破，直到刮完、挑止为止。推究用小枣蘸酒的意思，是取其以火攻火（用火性药物对抗火热病邪）的道理，这不如改用蓖麻油蘸着刮，如果没有蓖麻油，可以用麻汁（将蓖麻仁捣碎稍加水分，提取浓汁。）更快捷。我见过进行刮法和挑法治疗的人，往往等到瘟邪进入体内，出现谵语狂乱等症状时才使用，如果在初感病邪时就使用这种方法，应当效果更好。至于瘟疫，如果有咽喉方面的症状，则针刺少商穴。（刺法的穴位详见下文虾蟆瘟章节。）或者出现四肢厥冷、脉象伏匿等症候，则针刺少商穴，以及十指上靠近指甲边缘约一韭菜叶宽处的薄肉当中刺之，使血液流出，如果血不出，可用手捏挤出来，这些方法都有效。
刮针穴位位置：颈项后正中，刮一道；两旁左右大筋上，各刮一道；左右两肩软肉处（靠近肩井穴），各刮一道；两肩下脊背上的软肉处，各刮一道；脊柱两旁，竖向刮（自脖子下方至腰部），各两道；脊背后胁间肋缝中的软肉处，左右各刮数道；前胸侠旁软肉处，斜刮各一道；前胁间肋缝中的软肉处，左右各刮数道。每处如果刮出紫红色疙瘩，随即用针挑破，挤出血液。
吐法近来大多不被重视，但殊不知它确实有奇效。吴又可只说邪气在胸膈，想吐却吐不出来的情况才使用此法，但殊不知瘟疫不论患病天数，突然发生剧烈呕吐，是非常吉利的征兆，这是将要通过发汗而解表的意思。太史吴德宿患有胃痛病，疼痛剧烈时会呕吐，偶然感染瘟疫，十多天后，正值危急时刻，又犯了旧疾，胃口处剧痛，过了一会儿接着呕吐，困顿不止。大家都惊慌失措，请求我诊治，我说：“不要紧，可以不用药，会有喜事，不久将会通过发汗而痊愈。”众人因为我的话才安定下来。到了晚上，果然大汗出而痊愈。大概呕吐之中就含有发散的意思，那些触动沉寒积滞而引发呕吐的，尚且能发出瘟疫之汗，那么涌吐的功效又怎么可以埋没呢！
仙传吐法：治疗一切瘟疫、伤寒、伤风、伤酒、伤食，喝半碗百沸汤（滚开水），用手揉肚子，再喝再揉，直到腹部无法容纳，用鸡毛探喉催吐，吐完后煎葱汤饮用，盖好衣服取汗，非常快捷。刚得病时使用更为适宜。
萝卜子汤吐法：凡是邪气实于上焦，或者痰食气逆不通等症候，都可以使用吐法。可以代替瓜蒂散、三圣散。将萝卜子捣碎，用温水调和搅拌，慢慢饮下，一会儿就会呕吐，如果吐不干净，病邪必然从大便下行排出。
又一种方法：食盐少许，炒至发红，放入滚水中，宁可淡一点也不要过咸，取半碗，逐渐增加剂量饮用，自然引发呕吐，以祛除病邪为度。治疗饮食损伤导致的痞闷、膈痛、手足逆冷、尺脉全无，兼治冷气、鬼气、蛊毒。又一种方法：烧红的盐配合热童子尿，喝三次吐三次，治疗干霍乱。
There are two types of needle techniques: inserting the needle vertically into the flesh is called "Ci" (Piercing). Slanting the needle tip into the skin and flicking it upward, then immediately using the hand to pinch out evil blood is called "Tiao" (Lancing). There are four types of scraping methods: some use clam shells, some use porcelain bowls, some use hemp cloth strips (only for scraping arms), and some use copper coins. For all scraping, one may dip in clear water, salt water, or sesame oil. I have seen those treating plague by scraping with small dates dipped in distilled liquor; purple nodules resembling ripe mulberries appear, which are then slantedly lanced with a needle to extract blood, followed by scraping other nodules and lancing them until scraping stops and lancing ceases. The rationale behind using dates dipped in liquor is to employ fire to attack fire (using fire-natured agents against heat pathogens), but this is inferior to using castor oil for dipping and scraping. If unavailable, hemp juice (thick juice extracted from crushed castor beans with a little added water) is even more expedient. I have observed that practitioners of scraping and lancing often wait until the plague pathogen has entered the interior and symptoms such as delirium and mania appear before using these methods. Using these methods at the initial stage of infection would be more effective. As for plague, if there are throat-related symptoms, the Shaoshang point (LU-11) should be needled. (See the section on Toad Plague below for details on needling points.) Or, if symptoms such as cold extremities and faint pulse appear, needle the Shaoshang point (LU-11) and the thin flesh on the ten fingers (about the width of a leek leaf near the nail edge), pricking until blood flows. If blood does not flow, it can be expressed by pinching; all these methods are effective.
Scraping and Needling Points: One strip along the midline of the posterior neck; one strip on each of the large tendons on both sides of the neck; one strip on the soft flesh of both shoulders (near Jianjing GB-21); one strip on the soft flesh below both shoulders on the back; two vertical strips on each side of the spine (from below the neck to the waist); several strips on the soft flesh in the intercostal spaces between the spine and ribs on both sides; one diagonal strip on the soft flesh on both sides of the anterior chest; several strips on the soft flesh in the intercostal spaces of the anterior ribs on both sides. Wherever purple nodules appear after scraping, lance them with a needle and express the blood.
The vomiting method is rarely discussed nowadays, yet it possesses remarkable efficacy. Wu Keyou only stated that this method should be used when the pathogen is in the chest and diaphragm, causing the urge to vomit without success. However, he did not realize that regardless of the number of days since onset in plague, sudden severe vomiting is a very auspicious sign, indicating that resolution through sweating is imminent. Tai Shi Wu Desu suffered from chronic stomach pain, which induced vomiting when severe. He accidentally contracted plague. After more than ten days, while in a critical state, his old ailment recurred. His epigastrium hurt severely, followed by vomiting shortly after, leaving him exhausted and prostrate. Everyone was panicked and helpless, seeking my diagnosis. I said, "No harm, no medicine is needed; there is good news, and he will recover through sweating soon." Only then did everyone calm down based on my words. That night, he indeed sweated profusely and recovered. Vomiting inherently contains the meaning of dispersion. Those who induce vomiting by disturbing deep-seated stagnation can still induce sweat to resolve plague; thus, how can the merit of inducing vomiting be ignored?
Immortal Transmission Vomiting Method: Treats all plagues, Cold Damage (Shanghan), Wind Invasion, alcohol injury, and food stagnation. Drink half a bowl of boiling water, rub the abdomen with hands, drink again and rub again, until the abdomen cannot hold any more, then use a chicken feather to stimulate the throat to induce vomiting. After vomiting, drink scallion decoction, cover with clothes to induce sweating; this is very rapid. It is even more suitable for use at the very beginning of the disease.
Radish Seed Vomiting Method: Whenever excess pathogen is in the Upper Jiao (Upper Burner), or symptoms such as phlegm-food stagnation and rebellious Qi obstruction occur, vomiting can be used. It can replace Geng Ti San (Melon Peduncle Powder) or San Sheng San (Three Heroes Powder). Crush radish seeds, mix with warm water, stir, and drink slowly. Vomiting will occur shortly thereafter. If vomiting is incomplete, the pathogen will likely exit via defecation.
Another Method: Take a small amount of salt, fry until red-hot, add to boiling water. It should be slightly dilute rather than too salty. Take half a bowl and gradually increase the dosage while drinking. Vomiting will naturally occur. Use this to expel the pathogen. Treats bloating and oppression due to food injury, chest/diaphragm pain, cold extremities, and absent Chi pulse. Also treats Cold Qi, Ghost Qi, and Gu Poison. Another Method: Mix burnt salt with hot child's urine. Drink three times and vomit three times. Treats Dry Huoluan (Dry Cholera).
Another Method: Treats chest oppression due to food accumulation where sweating and purging are contraindicated. Decoct Dan Chi (Light Fermented Soybeans) and salt in water, drink to induce vomiting.
